Effect of the Different Soil Types on Chrysanthemum Cut Flower Quality

Cultivating annual crops in the high upland has the potential to increase avalanche and land erosion. Therefore, chrysanthemum extensification from high upland to medium upland can create sustainable agriculture. The differences between high upland and medium upland are microclimate and soil type. Meanwhile, the effect of soil type between the high upland and the medium upland on the chrysanthemum spray type quality is unknown. The study aimed to determine the effect of different soil types on the quality of chrysanthemums when planted in high upland. The study used a split plot design with two factors. The first factor was the type of soil, such as Andosol from the high upland and Latosol from the medium upland. The second factor was the chrysanthemum varieties, such as Yastayuki (white flower), Arosuka Pelangi (yellow flower) and Socakawani (red flower). The results showed that both Andosol and Latosol soil types could produce the same quality of chrysanthemum in all varieties when planted in high upland. The quality aspects of chrysanthemum were the plant height, the stem diameter, the number of flowers and flower color. Consequently, we could extend the cultivation of chrysanthemum in medium upland by using Latosol type soil.

Pre- and/or Postharvest Silicon Application Prolongs the Vase Life and Enhances the Quality of Cut Peony (Paeonia lactiflora Pall.) Flowers.

Peony is an important ornamental plant and has become increasingly popular for cut flower cultivation. However, a short vase life and frequent poor vase quality severely restrict its market value. The study described herein was conducted to investigate the effects of silicon application on the vase life and quality of two cut peony (Paeonia lactiflora Pall.) cultivars, ‘Taebaek’ and ‘Euiseong’. For pre- and/or postharvest silicon application, four experimental groups based on treatments were designed. With silicon treatment, the relevant growth attributes, including the shoot and leaf lengths, stem and bud diameters as well as the leaf width were all remarkably increased. In the postharvest storage, the addition of silicon to the holding solution in the vase was able to significantly extend vase life, delay fresh weight decrease, and improve vase quality, as characterized by the antioxidant enzyme activities and mechanical stem strength. Taken together, silicon application, regardless of the approach, was able to effectively prolong the vase life and enhance the quality of cut peony flowers.

Pre-harvest spray of GABA and spermine delays postharvest senescence and alleviates chilling injury of gerbera cut flowers during cold storage

Short vase life, capitulum wilting, neck bending, and postharvest chilling injury (CI) are major disorders have negative impact on quality and marketing of gerbera cut flowers. Low storage temperatures prolonging the vase life, but on the other hand leads serious CI which decreases the quality and consumer preferences. Spermine (SPER) and γ-aminobutyric acid (GABA) were identified as anti-aging factors delay the senescence and elevate the chilling tolerance in many species. Greenhouse-grown gerbera cv. ‘Stanza’ sprayed with 2 mM SPER and 1 mM GABA twice (2 T) or thrice (3 T). Cut flowers were stored at 1.5 °C and 8 °C postharvest to study the effects of GABA and SPER on senescence and CI. Vase life, CI and quality of cut flowers were improved by GABA and SPER treatments. No CI was observed in GABA-treated flowers at 1.5 °C; while, flowers sprayed with water showed severe CI. GABA treatments efficiently prolonged the vase life for 6–7 days more than the control (15 days). GABA and SPER increased the fresh weight, solution uptake, protein and proline contents, catalase, peroxidase, and superoxide dismutase activities, while decreased the electrolyte leakage, H2O2, and malondialdehyde contents, polyphenol oxidase, lipoxygenase, and phospholipase D activities. GABA and SPER significantly prolonged the vase life and prevented degradation of proteins and chilling damage and increased capacity of detoxifying and scavenging of H2O2 and reactive oxygen species (ROS), led to alleviate the negative consequences of the senescence and CI.

Antagonism between abscisic acid and gibberellin regulates starch synthesis and corm development in Gladiolus hybridus

Understanding corm development in flower bulbs is of importance for securing the quality of cut flowers and propagation of commercial stocks. Gladiolus is one of the most popular bulb plants worldwide. Its corm development is characterized by starch accumulation. Previous research has shown that phytohormones (especially gibberellin (GA)) are involved in tuber development. However, the relationship between abscisic acid (ABA)/GA and starch during corm development remains unclear. To gain deeper insights into the biological process of corm development, we performed a detailed anatomical characterization of different stages of corm development and analyzed phytohormone levels. Our study showed that corm development is linked to hormones (ABA and GA) and carbohydrates (sucrose and starch). Exogenous hormone treatment and silencing of endogenous hormone biosynthesis genes indicated that ABA positively regulates corm development, while GA acts as an antagonist of ABA function. A sucrose synthase gene (GhSUS2) was shown to be involved in the antagonism between ABA and GA. GhSUS2 was upregulated by ABA and downregulated by GA. The increase in the transcript level of GhSUS2 coincided with the development of corm/cormels. Silencing of GhSUS2 repressed corm development and starch accumulation. In conclusion, we propose that GhSUS2, an essential enzyme in sucrose degradation, is differentially regulated by ABA and GA and controls corm development in Gladiolus.

Effect of oxalic acid on vase life and antioxidative activities of ‘Mero Star’ cut lily flowers

Lily (Lilium L. hybrids) is sub-tropical cut flower that can be grown in open place or in green house and has consumer demand in local as well as in offshore markets. Short vase life, postharvest decay of flowering petals, activities of oxidative enzymes, malondialdehyde contents, electrolyte leakage and low water ratio are the main problems in marketing of cut lilies. This study was carried out to investigate the effect of oxalic acid (OA) treatments on vase life (12 days) and postharvest quality of ‘Mero Star’ cut lily flowers. The flowering stems were placed in 2, 4 and 6% aqueous solution of OA for 12 days at 20±2 °C with 70±5% relative humidity. Flowers placed in 6% OA solution exhibited longest vase life and flower diameter with higher relative water content and increased fresh weight and reduced flower decay. Reduced malondialdehyde contents and electrolyte leakage with higher activities of catalase, superoxide dismutase and peroxidase enzymes were also noted in 6% OA-treated flowers. In conclusion, exogenous postharvest application of 6% OA extended vase life and maintained postharvest quality of cut flowers by reducing electrolyte leakage and malondialdehyde contents with higher antioxidative enzymes activities.

Chemical preservation for increasing shelf life of Chrysanthemum indicum L. cut flower

Chrysanthemum indicum L. is the second most important ornamental and marketable flower from Asteraceae family in the world. Vase life is a main factor for evaluating the post-harvest quality of cut flowers that determine their marketability. Chrysanthemum is one of the top most cut flowers sold in international flower markets. The post-harvest study was carried out on chrysanthemum cut flower to observe the effect of different chemical preservatives solution for vase life. Here, the different chemical preservative treatments consisting of sucrose, salicylic acid, citric acid, aluminum sulphate and their combination were used to increase the vase life and the petal discoloration of chrysanthemum cut flowers. It was observed that all the preservatives treatments (expect T3) extend the vase life and reduced petal discoloration over the control. The result showed in containing T2 [sugar (4%) + salicylic acid (100ppm)] and T6 [citric acid (150ppm) + aluminum sulphate (500ppm) +7% sucrose] resulted in maximum vase life 18 days and 16 days in room temperature and reduced leaf browning more than control.

Impact of inorganic salts on vase life and postharvest qualities of the cut flower of Perpetual Carnation.

This study was carried out in the laboratory of Shangqiu Institute of Technology, Henan to investigate the effect of a different combination of inorganic salt on the quality and physiological characteristics of cut flowers (CFs) of Perpetual Carnation. Furthermore, to find out the best preservation solution of inorganic salt that can enhance the ornamental value of CFs of Carnation and prolong its vase life. Sucrose, 8-hydroxyquinoline, paclobutrazol, salicylic acid and different kinds of inorganic salts were added as a preservation solution. And the same amount of distilled water was used as control. The effects of these various inorganic salts on the morphological characteristics including vase life, changes in flower stems, fresh weight (FW) and water balance and the physiological characteristics including contents of malondialdehyde (MDA), cell membrane permeability and the contents of proline of carnation were investigated. The CFs placed in vase solution with inorganic salts showed significant changes in its morphology and physiological characteristics as compared to control. The changes in flower diameter (FD), FW, malondialdehyde and cell membrane permeability showed an increasing trend first and then decreasing. The value of water balance was observed with a downward trend. However, the vase life, FD, the contents of malondialdehyde, contents of proline and FW of CFs held in the preservative solution containing inorganic salts were increased than that of control. The fresh preservative solution contained sucrose 3% + 8-hydroxyquinoline (8-HQ) (200 mg·L‾1) + paclobutrazol (100 mg·L‾1) + salicylic acid (SA) (25 mg·L‾1) + CaCl2 (100 mg·L‾1) has the best effect on longevity (34 days), FW and FD of carnation CFs. This solution has improved the ornamental and physiological characteristics of fresh carnation CFs.

Effects of high CO2 and low O2 on biochemical changes in cut Dendrobium orchids

Exportation of cut flowers entails long distance transportation, and the quality of cut flowers deteriorates as the distance and transportation time increase. Low storage temperatures and modified atmosphere are commonly used to extend the life of cut flowers. As a result, this research explored the potential use of high CO2 and low O2 to prolong the shelf life of cut flowers. Specifically, this study examined the effects of high CO2 and low O2 storage on the biochemical changes in cut Dendrobium pink stripe orchid flowers. The experiments were conducted under normal and high CO2 and low O2 conditions, and results were compared. Under the normal condition, carbon dioxide (CO2) and oxygen (O2) concentrations were 0.03 % and 21 %. In the high CO2 and low O2 environment, CO2 was varied between 5 and 10 %; and O2 between 2, 4, 6, and 8 %. The storage temperature and relative humidity were 13 °C and 95 %. The originality of this work is the use of high CO2 and low O2 storage environments to investigate the biochemical changes in cut Dendrobium orchid flowers. The experimental results showed that high CO2 and low O2 significantly enhanced the storage life of Dendrobium orchid flowers (p < 0.05). The longest storage life of 28.33 days was achieved under 5 % CO2 and 2 % O2 atmosphere condition, compared with 11.67 days under the normal atmosphere condition. High CO2 and low O2 storage also helped to retain total anthocyanin content while lowering fresh weight loss, respiration rate, ethylene production, protein degradation, and protease activity.

Comparison of Growth Conditions of Cut Spray &lt;i&gt;Chrysanthemum&lt;/i&gt; in Smart Farm and Greenhouse

The yield and quality of cut flowers (Chrysanthemum) in a conventional greenhouse and a smart farm were assessed. The two sites were compared in terms of facilities, soils, and growth conditions. The three cultivars of cut spray chrysanthemums used in this study were ‘Abishag’, ‘Ford’, and ‘Henna’. The smart farm was equipped with 16 automatic sensor channels for monitoring temperature, humidity, CO2, nutri-culture solution, air flow, and light. Fog spray devices were used in the smart farm but not in the greenhouse, where temperature was lowered by opening side windows for ventilation. We found that cut chrysanthemums of excellent quality are produced in the smart farm, due to the uniform environment year-round. The chrysanthemum crop was harvested at the smart farm 3.5 times per year and produced an average of 129 plants/m2 annually, in one year, which is an improvement over the conventional greenhouse, in which the crop was harvested 3 times per year, yielding 91 crops/m2 annuallyin 1 year. The smart farm has an appropriate amount of organic matter and pH; however, the greenhouse has high organic matter. The electrical conductivity in the smart farm was 3.8 times higher than the corresponding value in the greenhouse. The three varieties grown on the smart farm were all superior to the greenhouse plants in terms of plant height, number of leaves, and stem diameter. On the other hand, chlorophyll content tended to be higher in the greenhouse plants. Through these results, we found that cut chrysanthemums of commercially excellent quality are produced in the smart farm, due to the uniform environment year-round using smart-farming system.

Tools for Cut Flower for Export: Is It a Genuine Challenge from Growers to Customers?

Currently, the cut flower market seems to be an export revenue in the world trade of the flower industry. The amount of exported cut flowers is impressive with increased production in various countries, especially in Korea. In the Fourth Industrial Revolution, automatic technologies are continuing to develop agricultural effective tools in the challenge of digital innovation. Thus, the low production costs set up in the field, greenhouse, or smart farm set up, and the short time of harvest must be considered within a few months. The postharvest quality of cut flowers presents freshness and long vase life, and the tools for postharvest handling are expected to optimize these. This review highlights the most important factors improving postharvest quality of cut flowers, the potential standard applicable techniques for commercial handling outlines of cut flower vase life, and recommendations for improving postharvest handling in the flower industry.

Use of Light Stimuli as a Postharvest Technology for Cut Flowers

Cut flowers are a unique aspect of the flora industry, and they are globally recognized as one of the most commercially produced ornamentals. Thus, it is necessary to increase their quality for consumers' satisfaction over a long period. The quality of a cut flower depends on its external characteristics such as color, length, volume, freshness, and fragrance as well as its perishability, which is determined by the duration of these external characteristics. Recent researches have shown that external light emission significantly affects several aspects of cut flower traits, such as; the vase life, petal color, and volatile compounds emission. Clarifying the relationship between these flower traits and light stimuli, which can increase the understanding of the mechanisms of these traits, can help to improve the quality of cut flower through light environmental control. This study proposes that the external light stimuli is an effective tool for improving the quality of cut flowers, and also highlights the several issues related to this proposal.

Effects of air-exposure time on water relations, longevity, and aquaporin-related gene expression of cut roses

In this study, we aimed to assess the effects of air-exposure treatment on water relations, longevity, and aquaporin-related gene expression of cut ‘Wild Look’ roses (Rosa hybrida L.). After harvest, cut rose flowers were placed directly in the tap water (exposed to air for 0 h) or exposed to air for 1, 2, or 3 h and then placed in tap water to recover. We determined the effects of air-exposure time on vase life, water relations, morphological and physiological characteristics, bacterial contamination, and on the expression of aquaporin-related gene of cut flowers. Our results revealed that cut flowers exposed to air for 0 h exhibited a highest postharvest quality. Exposure to air for 3 h significantly decreased the postharvest quality of cut flowers cultivated year-round owing to the early failure of water relations, such as maintaining a positive water balance for a short duration, high transpiration under dark conditions, and bacterial proliferation. Notably, in autumn or winter, exposure to air for 1 and 2 h also decreased vase life of cut roses. Exposure to air for 0 h reduced bacterial population at the basal of cut stem ends, decreased water stress, and maintained leaf chlorophyll fluorescence of cut roses cultivated year-round. Exposure to air for 0 h prevented water stress in cut flowers and increased the transcript levels of Rh-PIP2;1 and Rh-TIP in petals, resulting in maintained cell turgor of petals and improved flower diameter of cut roses. Understanding the relationship between air-exposed time and water relations, longevity, and aquaporin-related gene expression of cut roses may help to develop techniques and distribution systems to improve the vase life of cut roses.

Using Arachis pintoi leaf extracts in biosynthesis of silver nanoparticles for improving the vase life of cut carnation (Dianthus caryophyllus L.)

A biological method for synthesizing silver nanoparticles (SNPs) using the leaf extracts of Arachis pintoi Krapov. &amp; W.C. Greg. was developed. The optimum conditions of input materials were found with leaf autoclaving in 15 min, 20 g fresh leave, and 4 mM of silver nitrate (AgNO3). To study the role of time, temperature, and solution pH of the reaction, varying time reaction (5, 30, 60, 90, 120, 150, and 180 min), temperature reaction (10, 20, 30, 40, and 50oC) and pH of the solution (1, 3, 5, 7, 9, and 11) were investigated. The optimal biosynthesis conditions were achieved in 180 min of reaction time at 50oC and pH 11. The obtained nanoparticles have spherical and oblong in shape with average size of 26.4 nm. The SNPs in 4 concentrationss (5, 15, 25, and 35 ppm) combined with and without 2% sucrose extended vase life, enlarged flower diameter, and maintained increase the relative fresh weight with vase solution uptake rate. SNPs inhibited significantly the bacterial growth in the stem end and vase solution, reduced the blockage in stems and therefore promoted the postharvest quality of carnation cut flowers. Out of the treatments, administration of 5 ppm SNPs with 2% sucrose of vase solution gave the best results for all parameters. The biosynthesis SNPs could be applied as a promising preservative solution for carnation cut flowers.

Impact of environmental factors and mulching on growth, quality and yield of carnation (Dianthus caryophyllus L.) cv. ‘Loris’

Research was conducted at Hi-tech farm of Department of Floriculture and Landscape Architecture, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan to evaluate the effects of different mulches and environmental conditions on growth, quality and yield of carnation cut flowers under naturally ventilated polyhouse conditions. Different types of mulch were replicated six times in a plot of 1.0 × 1.0 m size. Mulching with spent mushroom compost (M1), grass (M2), pine needles (M3) along with control (M0) was done 15 days after transplanting of rooted cuttings. The results revealed that plants mulched with spent mushroom compost (M1) recorded maximum duration of flowering (28.77 & 28.97 days), minimum days taken to reach harvesting stage (141 & 132.33 days), highest number of cut flowers per plant (6.50 & 9.47) and vase life (18.30 & 23.37 days) during first and second flush, respectively as compared to control. The maximum temperature and relative humidity inside greenhouse were 39.8oC and 85 %, respectively. However, maximum soil temperature was recorded in the plots mulched with pine needles.

EFFECT OF POTASSIUM NITRATE AND ADENOSINE TRIPHOSPHATE ON PRE- AND POST-HARVEST GERBERA (GERBERA JAMESONII L.) PLANTS

The pot experiment was conducted during the two consecutive seasons of 2016 and 2017 in plastic house at Horticulture Research Station, Mansoura, Dakahlia Governorate, Egypt as pre-harvest treatments. The main objective of the first experiment was to study the effect of two rates of adenosine triphosphate(0.0 and 7.0 g/l) alone or combined with potassium nitrate at the dose of 2.5, 5.0, 7.5 and 10.0 g/pot, on vegetative growth, flowering and chemical constituents of gerbera (Gerbera jamesonii). The highest values of plant height, number of leaves per plant, leaf area, number of flowers per plant, flower diameter, stalk length as well as the contents of total chlorophyll, carbohydrates, N, P, and K in plants were achieved with adenosine triphosphate(ATP) at 7 g/l as weekly foliar spray with significant difference compared to control. Also, increasing potassium nitrate from 2.5 up to 10.0 g/pot gradually increased the above mentioned parameters during both seasons. Furthermore, using the highest doses of potassium (7.5 and 10.0 g/pot) in interaction with ATP at 7 g/l significantly increased gerbera growth, flowering and chemical constituents compared to untreated plants and the other interaction treatments. From the first experiment the best interaction treatments were 7.5 and 10.0 g potassium nitrate/pot plus1 7 g ATP/l, these treatments were in the second experiment to study the effect of different pulsing solutions on flower vase life, solution uptake and flower fresh weight of gerbera. The obtained results revealed that, the longest vase life of gerbera and the highest quality cut flowers were obtained by using the combination treatments between (7.5 g potassium nitrate/pot + 7 g ATP/l) combined with 3% sucrose + 8-HQS at 200 ppm as holding solution. By studying simple correlation coefficients, gerbera cut flowers vase life exhibited strong positive relationship with each of water uptake and flower fresh weight which, indicated that the increase in these parameters was accompanied by increasing vase life of gerbera cut flowers under the effect of interaction treatments of pre and postharvest.

Acid influences postharvest quality and oxidative activity of gerbera cut flowers

Gerbera is a very popular ornamental plant and used in ornamental gardens or as a cut flower. However, as a cut flower, postharvest quality is minimal, which requires solutions to ensure its longevity, especially with acidic solutions. The study was conducted understand if the action of maintenance solutions with acids influence the postharvest physiology of gerbera cv. ‘Piang’. The experimental design was factorial completely randomized consisting of two factors: four postharvest treatments and seven evaluation times. The flowers were kept in 200 mg L^-1 of citric acid solution (ACS reagent, ? 99.5 % - Sigma-Aldrich), 200 mg L^-1 of boric acid solution (ACS reagent, ? 99.5 %) and 200 mg L^-1 of salicylic acid solution (ACS reagent, ? 99.0 %) and potable water as a control. During the postharvest period, fresh mass loss, water absorption, petal luminosity, total longevity, peroxidase (POD) enzyme activity, superoxide dismutase (SOD) activity, total protein and total carbohydrate content were studied. Treatments with boric and salicylic acids recorded higher percentage of fresh weight loss. Citric acid showed higher water absorption rate and better appearance in the luminosity of the petals. The total protein and carbohydrate content decreased during the evaluation period but in the citric acid treatment, the reduction was not so significant. On the other hand, citric acid induced higher peroxidase and superoxide dismutase activity in the second day of evaluation and lower activity until the tenth day.

Implementation of Chrysanthemum Post-Harvest Technology in Tomohon City to Extend Storage Time

Chrysanthemum (Dendranthema grandiflora) is an ornamental plant that has high economic value, including flowers that are in great demand at domestic or abroad. As cut flowers, chrysanthemums are used for decoration and flower arrangements at weddings, and for opening new offices. The quality of cut flowers depends on the appearance and durability of freshness. Flowers with prime quality have a higher sale value compared to low-quality cut flowers. To maintain the quality of prime cut flowers still need to be implemented several treatments, especially when the flowers are ready to harvest to the consumers. The handling of post-harvest chrysanthemums is an important factor that is inseparable from the stages of cultivation and greatly influences the selling value and added value that will be obtained by farmers and traders. The use of pulsing and holding liquid during display will extend the chrysanthemum vase life. By implementing post-harvest chrysanthemums in accordance with handling procedures (SOP), chrysanthemums will be obtained that can meet quality standards and can provide added value for farmers and flower traders

Root-zone cooling by cold energy from LNG regasification process for quality improvement of flower and bulb of Hippeastrum

In an attempt to improve growth and flowering of Hippeastrum ‘Apple Blossom’ grown in areas of tropical climate, the effect of root-zone cooling on root growth and flowering was investigated. Hippeastrum bulbs were harvested and transplanted to grow in planting-beds using expanded clay as the growing medium. The root-zone cooling methods were conducted using three treatments, namely T1) no cooling (NC) as the control treatment, the average root-zone temperature was 23 ± 2 °C; T2) short-term root-zone cooling (SC) at 11 ± 2 °C by circulating cool water through pipes installed on the beds for 13 weeks; and T3) long-term root-zone cooling (LC) at 11 ± 2 °C throughout the experiment (66 weeks after planting [WAP]). At 29 WAP, plant growth in terms of plant height and root length in the control treatment (NC) was less than the plant growth in other treatments, while at 66 WAP, plant height was not different between treatments. The root length gradually increased when the plant was grown by soil cooling at 11 ± 2 °C throughout the experiment (LC). In the first round of flowering (29 WAP), the results showed that the flowering percentage was not different between treatments. However, at the second round of flowering (66 WAP), plants grown under long-term root-zone cooling at 11 ± 2 °C (LC) had a higher flowering percentage (94.6%) than SC (33.3%), while the NC treatment plants did not flower. The bulb quality, photosynthetic rate, and stomatal conductance were discussed in this study. It was concluded that decreasing the temperature of the rhizosphere increased plant growth, improved the quality of flowers and bulbs, and also stimulated the flowering cycle of Hippeastrum. This result is beneficial for improving the quality of Hippeastrum cut flower in Thailand using a root-zone cooling system.

Postharvest Spectral Light Composition Affects Chilling Injury in Anthurium Cut Flowers.

The effect of the lighting environment during postharvest storage of ornamentals has largely been neglected in previous research. Anthurium is a cold-sensitive species originating from tropical climates and is widely cultivated all around the world for its colorful spathes. To investigate the effects of light spectrum on the performance of Anthurium cut flowers under cold storage, two cultivars [Calore (red spathe) and Angel (withe spathe)] were placed at low temperature (4°C), either in darkness (D) or under different light spectra [red (R), blue (B), 70:30% red:blue (RB), and white (W)] at an intensity of 125 µmol.m−2.s−1. In both cultivars, the longest and shortest vase lives were observed in spathes exposed to the R and B spectra, respectively. In both cultivars, electrolyte leakage (EL) of spathe was highest under the B and W spectra and lowest under the R spectrum. The highest rate of flower water loss from the spathes was observed under the B-containing light spectra, whereas the lowest rate of water loss was observed in D and under the R spectrum. Negative correlations were observed between EL and vase life and between anthocyanin concentration and EL for both Anthurium cultivars. A positive correlation was found between anthocyanin concentration and vase life. For both Anthurium cultivars, spectral light composition with higher percentage of B resulted in higher EL and as a result shorter vase life in cut flowers under cold storage condition. The negative effect of the B light spectrum on vase life of Anthurium can be explained through its effect on water loss and on oxidative stress and membrane integrity. The quality of Anthurium cut flowers should benefit from environments with restricted B light spectrum during postharvest handling.
