Plant Growth, Fruit Yield and Quality of Strawberry (Fragaria × ananassa Duch.) as Affected by Bioorganic Nutrient Sources

Unveiling impact of word concepts on Enhancement or Reduction of Spoilage Molds growth and shelf life of strawberries

Aim: In the present study, the objective was to investigate the impact of written words on inhibiting the growth of molds in the cultivation medium and on strawberry fruit. Methods: Two pairs of opposite written words with positive or negative connotations (such as love-hate and peace-war) were selected to study their effects on the inhibition growth of two of the most common fruit molds (Aspergillus niger and Botrytis cinerea) at various incubation periods (ranging from 1 to 5 days) at 25°C. Results: The findings indicated that there were no statistically significant differences (P≥0.05) in the growth of both molds on the medium when exposed to words with opposing meanings. However, when strawberries were inoculated with the mold spores and subjected to written words with positive connotations, such as "love" and "peace," a significant reduction in mold growth was observed (P<0.05) compared to the control group. Furthermore, the presence of the word "love" resulted in the longest shelf life for strawberries contaminated with either A. niger or B. cinerea during cold storage period, with durations of 39 and 28 days, respectively. Conclusion: These findings shed light on unexplored aspects and propose novel perspectives regarding the potential use of written phrases and words to enhance food quality and mitigate fungal contamination in fruits and vegetable products.

Impact of Plant Growth Regulators on Strawberry Plant – A Review

Strawberry is soft, luscious, nutritious, tasty, and perishable fruit which are grown in temperate climatic conditions where the plant like a small perennial herb and also grown in a sub-tropical climate whose plant behaves as an annual belonging to the family Rosacea. Application of growth regulators has been practiced commercially to increase the production and quality of crops. Gibberellic acid has a significant role in plant heights, number of runners, number of flowers, fruit set percentage, number of fruits, fruit size, fruit weight and fruit quality. In this study we present influence of gibberellic, yield and fruit quality of strawberry, Triacontanol and NAA on growth on yield and quality, chlormequat. Gibberellins are well-known for acting as a long-day hormone in short-day plants. Gibberellin treatment increases vegetative growth but limits flower development applied gibberellic acid promoted blooming and growth. However it was observed that the highest effect on leave, runner, crown, inflorescence and flower production. Triacontanol, Activol and NAA resulted in increased vegetative growth of strawberry as compared control. Highest crown height (7.2cm) was obtained with 100 ppm Activol and highest leaf number/plant (7.2) and leaf region (49.4m2) were obtained with 50ppm tricontanol treated plants.

This case study investigates the impact of different bio-stimulants, including Novel prime organic liquid nutrient, Vermi wash, and Cow urine, on vegetative growth, flowering, and fruit yield of sweet sensation variety of strawberry plants. An intensive research work was carried out at an experimental land located in north Konkan zone of Maharashtra, India. The experiment employs a Completely Randomized Design (CRD) with three replications to evaluate growth at various stages and yield parameters. The results demonstrate that the strategic application of 2% concentration of Novel prime organic liquid nutrient and 2% Vermiwash significantly improves the plant growth and yield of strawberry. This treatment remarkable yielded 5418 kg/ha, while the appreciable yield achieved to 4733 kg/ha for the Vermiwash treatment. The results also highlight the potential of sustainable strawberry cultivation and suggesting its viability for countries that traditionally depend on rain-fed crops. This may significantly improve the pattern of agricultural practices in those regions. Strawberry cultivation is an economically significant horticultural practice worldwide. Enhancing the growth, quality, and yield of strawberry plants is crucial for improving production and profitability.

Exogenous GR24 Inhibits Strawberry Tillering by Affecting the Phytohormone Signaling and Sugar Metabolism Pathways

Tillering is an important part in strawberry growth, and strawberries can reproduce nutritionally through stolons to generate genetically stable offspring. However, excessive tillering during the fruit-growing stage can negatively impact fruit yield and quality. In this study, different concentrations of exogenous rac-GR24 (GR24) are used to treat the strawberry plants. It was found that GR24 effectively inhibited the sprouting of strawberry stolons, while promoting the growth of the stems and leaves. Among the treatments, the most effective concentration was found to be 5 μmol/L GR24. This treatment resulted in a decrease in the glucose content in the strawberry crowns and also caused changes in the contents of two endogenous phytohormones, gibberellic acid (GA3) and trans-zeatin riboside (tZR). Transcriptome data further suggested that exogenous GR24 may inhibit strawberry plant tillering by affecting various phytohormone signaling pathways and the sugar metabolism pathway. In 5 μmol/L GR24-treated plants, the expression level of type-B response regulator (B-ARR) was down-regulated and the expression level of CYTOKININ RESPONSE 1 (CRE1), histidine-containing phosphotransfer protein (AHP), and type-A response regulator (A-ARR) were up-regulated, suggesting the inhibition of the cytokinin (CTK) signaling pathway. The down-regulation of auxin (AUX) and auxin response factor (ARF), as well as the up-regulation of auxin/indole-3-acetic acid (AUX/IAA), led to the inhibition of the indole-3-acetic acid (IAA) signaling pathway. Additionally, the up-regulation of pyrabactin resistance 1/ pyrabactin resistance 1-like (PYR/PYL), non-fermenting 1-related protein kinase 2 (SnRK2), and ABRE binding factors (ABF) and the down-regulation of protein phosphatase 2C (PP2C) were observed in the up-regulated abscisic acid (ABA) signaling pathways. In the sugar metabolism pathway, the up-regulation of invertase (INV), hexokinase (HK), and fructokinase (FRK) and the down-regulation of trehalase (TREH) and beta-amylase (BMY) led to a decreased glucose synthesis and an increased glucose consumption. Therefore, GR24 can effectively inhibit strawberry plant tillering through these pathways, making it an effective reagent for tillering inhibition.

Impact of Nano-fertilizers and Nutrient Management on Growth and Yield of Strawberry

In the pursuit of enhancing agricultural practices, this research delves into the intricate interplay between nano-fertilizers, nutrient management strategies, and their collective impact on the growth and yield metrics of strawberries. The present research was carried out to ascertain the impact of nano-fertilizers (ZnO and FeO) and integrated nutrients management (Phosphate solubilizing bacteria (PSB) & Azotobacter) on strawberry (Fragaria x ananassa Duch.) Cv. Winter Dawn. The results of present work showed different treatments of nano fertilizers and nutrients management has variable impact on strawberry growth such as treatment 7 (T7: 50% Recommended dose of fertilizer) + FYM + vermicompost + Azotobacter + 150 ppm nano-ZnO + 150 ppm nano-FeO) showed highest growth parameters regarding number of leaves (14), plant height (11.24 cm), leaf area (74.86 cm2) and chlorophyll content (52.41 μmol/m2) etc. compared with other treatments. However, treatment (T9: 50% RDF + FYM + vermicompost + Azotobacter + PSB + nano-ZnO + nano-FeO) indicated bit similar regarding number of leaves (13.33), plant height (11.96 cm), leaf area (74.08 cm2) and chlorophyll content (53.06 μmol/m2) etc. The biochemical parameters were also observed higher in treatment (T9). Considering above results, it can be concluded that the dose, i. e., 50% RDF along with FYM, vermicompost and Azotobactor + ZnO + FeO (150 ppm) could enhance growth and yield of strawberry.

Biostimulatory Effects of Chlorella fusca CHK0059 on Plant Growth and Fruit Quality of Strawberry.

Green algae have been receiving widespread attention for their use as biofertilizers for agricultural production, but more studies are required to increase the efficiency of their use. This study aimed to investigate the effects of different levels of Chlorella fusca CHK0059 application on strawberry plant growth and fruit quality. A total of 800 strawberry seedlings were planted in a greenhouse and were grown for seven months under different Chlorella application rates: 0 (control), 0.1, 0.2, and 0.4% of the optimal cell density (OCD; 1.0 × 107 cells mL-1). The Chlorella application was conducted weekly via an irrigation system, and the characteristics of fruit samples were monitored monthly over a period of five months. The growth (e.g., phenotype, dry weight, and nutrition) and physiological (e.g., Fv/Fm and chlorophylls) parameters of strawberry plants appeared to be enhanced by Chlorella application over time, an enhancement which became greater as the application rate increased. Likewise, the hardness and P content of strawberry fruits had a similar trend. Meanwhile, 0.2% OCD treatment induced the highest values of soluble solid content (9.3-12 °Brix) and sucrose content (2.06-2.97 g 100 g-1) in the fruits as well as fruit flavor quality indices (e.g., sugars:acids ratio and sweetness index) during the monitoring, whilst control treatment represented the lowest values. In addition, the highest anthocyanin content in fruits was observed in 0.4% OCD treatment, which induced the lowest incidence of grey mold disease (Botrytis cinerea) on postharvest fruits for 45 days. Moreover, a high correlation between plants' nutrients and photosynthetic variables and fruits' sucrose and anthocyanin contents was identified through the results of principal component analysis. Overall, C. fusca CHK0059 application was found to promote the overall growth and performance of strawberry plants, contributing to the improvement of strawberry quality and yield, especially in 0.2% OCD treatment.

This study was conducted at the research station of the College of Agriculture - University of Anbar during the agricultural season 2021 to study the effect of adding types of organic fertilizer (without addition, poultry manure, manufactured organic fertilizer) which are symbolized by (M0, M1, M2) respectively. The combination of the recommendation and half of the recommendation with spraying with a some elements that contains calcium, boron, zinc, magnesium, amino acids and molybdenum, and it was at 6 levels (T1 fertilizer recommendation without spraying, T2 fertilizer recommendation with growth stimulator spray 2.5 g L-1, T3 fertilizer recommendation with a spray of 5 g L−1, T4 is half recommended without spraying, T5 half recommended with spraying 2.5 g L−1 and T6 half recommended with spraying 5 g L−1) on some vegetative growth and yield characteristics of strawberry. The results showed that the addition of organic fertilizer and poultry manure gave the highest value in the number of leaves (80.82leaf plant−1), the number of crowns (7.328 crown plant−1), the leaf area (88.81 dm2 plant−1), and the leaf content of chlorophyll (333.69 mg 100 g weight fresh-1) and the weight of the fruit is (41.47 g fruit −1) and the total yield is (712.17 g plant −1).

Effects of multiple N, P, and K fertilizer combinations on strawberry growth and the microbial community.

Nitrogen (N), phosphorus (P), and potassium (K) exert various effects on strawberry (Fragaria ananassa Duchesne) yields. In this study, we employed an orthogonal experimental design (T1-T9) with three fertilization treatments (N, P, and K) at three levels to identify an optimal fertilization scheme for strawberry cultivation. The effects of fertilizer combinations the rhizosphere soil microbial community were also explored by using bacterial full-length 16S rRNA and fungal ITS (internal transcribed spacer) sequencing (30 samples for each analysis). The results showed that the average plant height and leaf area of the fertilized groups were 24.6% and 41.6% higher than those of the non-fertilized group (T0). After 60 d of planting, the sucrase activity in the T6 group increased by 76.67% compared to the T0 group, with phosphate fertilizer exerting a more significant impact on sucrase activity. The T6 treatment group had the highest alpha diversity index among bacterial and fungal microorganisms, and had a different microbial community structure compared with the control group. The most abundant bacterial taxa in the strawberry rhizosphere soil were Proteobacteria, Bacteroidota, and Acidobacteriota, and the most abundant fungal phyla were Monoblepharomycota, Glomeromycota, and Mucoromycota. Application of the optimal combined fertilizer treatment (T6) significantly increased the abundance of Proteobacteria and altered the abundance of Gemmatimonas compared to other treatment groups. Notably, Gemmatimonas abundance positively correlated with strawberry plant height and soil N, P, and K levels. These findings indicated that the relative abundance of beneficial bacteria could be enhanced by the application of an optimal fertilizer ratio, ultimately improving strawberry agronomic traits.

Development of individual elements of a protocol for sustainable growth and propagation of garden strawberries (Fragaria ananassa Duch.) under aseptic conditions

Garden strawberry (Fragaria ananassa Duch.) is one of the most valuable fruits the demand for which in the food market is consistently high. One of the limiting factors for achieving consistently high-quality strawberry yields is the presence of diseases caused by bacteria, phytoplasmas, viruses, and viroids. In order to intensify the technology of garden strawberries cultivation, the problem of production in significant volumes of genetically constant material free from pathogens is essential. Biotechnological methods are currently relevant technologies that allow mass production of planting material with high phytosanitary and genetic quality. The purpose of the study is to update the protocol for microclonal propagation of garden strawberries to obtain virus-free planting material. The research was conducted in the micropropagation laboratory of LLC «Blahodatne» (ТеvittaTM) Cherkasy region, Ukraine using the «Alba» and «Present» strawberry cultivars. A series of experiments were conducted according to the «step by step» principle on two types of explants: buds and meristems. The determinants for obtaining aseptic cultures from bud and meristem explants were investigated. The trophic influence was studied in media with different mineral content (at the multiplication stage) and sucrose concentrations during rhizogenesis. Among the phytohormonal determinants during the multiplication stage, the best combination among those investigated was the use of substances with cytokinin activity consisting of BAP at 0.2 mg/l and kinetin at 0.8 mg/l. The addition of 0.1 ml/l of «Gibb plus preparation» (GK4 + GK7) was effective for the reproduction rate increasing. Growing of donor explants in media with BAP at 0.2 mg/l, kinetin at 0.3 mg/l, and adenine at 0.5 mg/l, compared to the control (BAP at 1.0 mg/l) improved rhizogenesis in regenerants. The highest root formation rates were observed in the variant with 4 % of sucrose (40 g/l). Key words: propagation; microclonal propagation; aseptic culture; trophic and hormonal determination.

Improving the growth, yield and iron concentration of strawberry using sodium hydrosulfide (NaHS) under soilless culture

Required iron (Fe) for the growing plants in soilless culture could be obtained from various Fe sources such as chelates and ferrous sulfate (FeSO4). Despite the low cost of FeSO4, this source is rarely used due to the low Fe solubility at a high pH. Here, the role of sodium hydrosulfide (NaHS) in improving growth and iron availability in strawberry (Fragaria × ananassa cv. Paros) grown in FeSO4 culture solution was reported. The plants were grown hydroponically with two Fe sources, Fe-EDTA and FeSO4 along with three levels (0, 0.2, and 0.5 mM (of H2S donor, NaHS. The results showed that vegetative growth and yield of strawberry under FeSO4 source were lower than Fe-EDTA treated plants. Using NaHS significantly improved vegetative and reproductive growth, yield, chlorophyll SPAD value, maximum efficiency of photosystem II (Fv/Fm), and Fe availability of strawberries under FeSO4 source. Exogenously applied NaHS reduced the hydrogen peroxide (H2O2) and malondialdehyde (MDA) production and electrolyte leakage (EL) in the leaves by enhancing enzymatic antioxidant activity (ascorbate peroxidase, superoxide dismutase, and catalase) in FeSO4 source. Moreover, NaHS affected fruit yield under Fe-EDTA utilization and showed a significant increase in yield amount (by 29.75%) compared to control. In general, there were no significant differences between the two levels of NaHS, 0.2 and 0.5 mM. Our results indicated that H2S affects the maintenance of cell membrane integrity and subsequently iron availability by strengthening the enzymatic antioxidant system and reducing oxidative stress.

Development of Active Antibacterial CEO/CS@PLA Nonwovens and the Application on Food Preservation.

The biodegradable activity antibacterial materials have been widely applied on food preservation because they not only protect foods from pathogenic attacks but also relieve environmental pollution. Biodegradable melt-blown nonwovens (MB) have several advantages over the other materials in terms of a simpler and more environmentally friendly fabrication process, higher specific surface area, and lower cost. Herein, polylactic acid (PLA) MB is first modified by polydopamine (PDA) to activate the surface. Then, chitosan (CS) and cinnamon essential oil (CEO) are used to decorate the surface of the modified PLA MB via a simple one-pot method to prepare CEO/CS@PLA MB with different CEO contents. Compared with PLA MB, CEO/CS@PLA MB had a rougher surface and larger average fiber diameter, while the average pore diameter and air permeability reduced. The input of CEO led to a decrease in the tensile strength of CEO/CS@PLA MB and an obvious increase in the elongation at break. The combination of CS and CEO shows excellent synergistic antibacterial effect. The antibacterial efficiencies of CEO/CS@PLA MB against Escherichia coli and Staphylococcus aureus enhance with the increase of the CEO content. When the weight ratio of CS to CEO is 1:2, the antibacterial efficiencies of CEO2/CS@PLA MB against E. coli and S. aureus are 99.98 and 99.99%, respectively. When being applied to the preservation of fresh strawberry, CEO2/CS@PLA MB can effectively inhibit the microbial growth in strawberry and reduce decay, which extends the shelf time of strawberry.

Watermoss Mulching Stimulates the Productivity and Physiochemical Properties of Strawberry in the Tropical Ecosystem of Southern Bangladesh

Strawberry is one of the most lucrative antioxidants and phytochemicals enriched temperate fruits. Nevertheless, good-quality fruit production requires special soil management practices like mulching and other strategies in tropical and sub-tropical regimes with short and dry winters. In the present research, strawberry var. BARI Strawberry-3 was cultivated using Asian watermoss (AW), water hyacinth (WH), paddy straw (PS), black polythene (BP), and silver polythene (SP) mulching along with control at the tropical weather-inclined southern part of Bangladesh from October 2018 to April 2019. The aim was to evaluate the comparative influences of those organic and synthetic mulches on root and shoot growth phenology along with subsequent reproductive behaviors, fruit yield, and fruit biochemical properties of strawberries under such an ecosystem. The experiment was conducted in a randomized complete block design with four replications. Mulching exhibited statistical superiority over control for strawberry growth, yield, and fruit quality indicators, where organic mulches performed better than others. Among the mulches, AW mulching produced the healthiest plant, having maximum plant height (20.40 cm), leaf number (23.33 per plant), canopy diameter (34.30 cm), single leaf area (100.06 cm2), and root length (19.05 cm) resulting in the highest root and shoot biomass. Though the plants received AW mulch required maximum duration from transplanting to flowering (47.88 days) and flowering to harvest (29.60 days), those plants produced the highest number of flowers (21.20 per plant) as well as fruits (19.63 per plant), and ultimately the utmost fruit yield (370.02 g/plant and 15.42 kg/ha) being significantly dissonant from all other treatments. Thus, a 57.57% yield increase over control was recorded from AW mulching. Furthermore, statistically, the maximum total soluble solids (TSS) (9.93%), TSS/acidity ratio (17.37), and vitamin C (58.30 mg/100 g), but the minimum titratable acidity (0.57%) content of strawberry was noticed in AW treatment. WH and BP mulches had statistical consistency with the best treatment for a few attributes. Therefore, crop residues, aquatic plants, or their by-products can be used as mulch for quality strawberry production in dry winter, especially in tropical and subtropical regions.
