Physiological responses of coriander (Coriandrum sativum L.) to exogenous 2,4-epibrassinolide at different concentrations

BackgroundBrassinolide, known as the seventh plant hormone, can improve the photosynthetic capacity of plants, promote plant growth and development, promote the formation of horticultural crop yield, improve the quality of horticultural crops, and also improve the ability of plants to resist biological and abiotic stresses.ResultsThe effects of different concentrations of exogenously sprayed 2,4-epibrassinolide (EBR) on growth, physiological and photosynthetic characteristics of ‘All-round large leaf coriander’ were studied in substrate culture. The results showed that 0.05, 0.1, and 0.5 mg.L− 1 EBR promoted the growth of coriander and increased the aboveground fresh and dry weights, with 0.5 mg.L− 1 EBR having the most significant effect. Spraying 0.1 mg.L− 1 EBR increased the content of soluble sugars and protein of coriander leaves. Spraying 0.1 and 0.5 mg.L− 1 EBR significantly increased the chlorophyll content and photosynthetic parameters of coriander leaves, and 0.5 mg.L− 1 EBR also significantly increased the chlorophyll fluorescence parameters of coriander leaves. Spraying 0.5 mg.L− 1 EBR upregulated the expression of CsRbcS, CsFBPase, and CsAld. Correlation analysis showed that aboveground fresh weight under exogenous EBR treatment was significantly positively correlated with aboveground dry weight, plant height, Pn, Gs, Ci, and CsAld (P < 0.05), and soluble sugar content was significantly positively correlated with the number of leaves, Y(II), qP, and CsRbcS. The results of the principal component analysis (PCA) showed that there was a significant separation between the treatment and the control groups. Spraying 0.5 mg.L− 1 EBR can promote the growth of coriander, improve the quality of coriander leaves, and strengthen coriander leaf photosynthetic capacity. This study provides new insights into the promotion of coriander growth and development following the application of exogenous EBR.ConclusionExogenous EBR treatment increased coriander plant height, leaf growth and aboveground dry weight, and enhanced photosynthesis. Exogenous spraying of 0.5 mg.L− 1 EBR had the most significant effect.

Coriander (Coriandrum sativum L.) in Combination with Organic Amendments and Arbuscular Mycorrhizal Inoculation: An Efficient Option for the Phytomanagement of Trace Elements-Polluted Soils.

The cultivation of coriander (Coriandrum sativum L.) destined for essential oils production was recently presented as an innovative and economically viable alternative for the phytomanagement of trace elements (TE)-polluted soils. However, Cd accumulation in shoots has proven to be an obstacle in the valorization of the distillation residues and the development of these phytotechnologies. The present study aimed to evaluate the effect of arbuscular mycorrhizal fungus (Funneliformis mosseae) inoculation and organic amendment application on the soil TE bioavailability and plant uptake, as well as on the soil quality and health improvement. The application of compost and sewage sludge improved the growth of coriander and Cd and Zn immobilization in soil, resulting in reduced Cd plant uptake. A synergistic effect of arbuscular mycorrhizal fungi (AMF) inoculation and organic amendments was observed in the decrease in the extractable soil Cd and Zn concentrations, but not in the Cd plant uptake. Despite a significant decrease in Cd accumulation in shoots, coriander retained its accumulative phenotype, with a metal bioconcentration factor close to 1. Furthermore, both the vegetation and the organic amendments improved the soil quality and health by increasing its microbial biomass, as estimated by phospholipid fatty acids, soil enzyme activities (dehydrogenase, phosphatase, β-glucosidase, and cellubiosidase), and the bacterial metabolic function and diversity. The findings demonstrate the potential of C. sativum, particularly in combination with organic amendments and AMF inoculation, for the phytomanagement of TE-polluted soils and soil quality and health improvement.

GROWTH PERFORMANCE OF CORIANDRUM SATIVUM L. INOCULATED WITH BIOFERTILIZERS-AN INITIAL STUDY

Biofertilizers are cheap, eco-friendly, improve soil fertility and plant nutrition within short time, and are effective components in organic farming. The present field study was carried with eight treatments to study the effect of Azospirillum, Phosphobacterium and AM fungus and their combination on primary growth characters coriander. The experiment was conducted in a factorial randomized block design. The collar diameter, plant height and number of leaves were significantly more in treatment with combined inoculation of Azospirillum + Phosphobacterium + AM fungus (T7) than control (T0). The increase in primary growth parameters in treatments with biofertilizers may be due to enhance the uptake of nitrogen, phosphorous and other essential nutrients for the growth of coriander.

Role of exogenously applied putrescine in amelioration of cadmium stress in Coriandrum sativum by modulating antioxidant system

Abiotic stress reduces the plant growth and biomass production. Putrescine (Put) may be applied to alleviate numerous types of abiotic stresses in plants. The present research was intended to evaluate the role of exogenously applied Put in extenuation of cadmium (Cd) stress in coriander plants. Coriander seeds primed with 0.25, 0.5, and1 mM Put were allowed to grow in 50 mg kg−1 Cd contaminated soil for one month. Put treatment improved seed germination, gas exchange attributes, root growth and shoot growth of coriander. The improved activity of stress-responsive enzymes such as superoxide dismutase, catalase and peroxidase, besides amplification of proline was observed in Put treated seedlings under Cd stress. In addition, a reduced amount of total soluble protein and sugars content were noticed in Cd stressed seedlings. Nevertheless, Put reduced MDA level in treated plants. Our results demonstrated that Put mitigated Cd induced stress by modulating antioxidants and photosynthetic activity of coriander plants. Novelty statement Most of the researchers have studied the role of endogenous putrescine in alleviation of plant stress. However, during current study, we primed coriander seeds with putrescine. Our results elucidated very promising role of exogenously applied putrescine in stress mitigation and growth improvement of coriander seedlings under Cd stress. The findings of current study advocate the application of putrescine for stress alleviation in crop plants.

Selenium nanoparticles reduced cadmium uptake, regulated nutritional homeostasis and antioxidative system in Coriandrum sativum grown in cadmium toxic conditions

Nanotechnology has become a valuable novel approach to manage several environmental challenges through providing innovative and effective solutions. Heavy metal stress is an important abiotic limiting factor. Seed priming with selenium (Se) alleviates various kinds of environmental stresses; yet, the potential of seed priming with selenium nanoparticles (SeNPs) under cadmium (Cd) stress for coriander crop has never been evaluated. This research work was designed to explore the effects of seed priming with three levels (0, 5, 10 and 15 mg L−1) of SeNPs solution on the physio-biochemical characteristics, nutrition, antioxidative defense system and growth of coriander under Cd stress. Cadmium toxicity reduced chlorophyll content, photosynthetic activity and growth of treated plants. Moreover, Cd stressed plants exhibited modulations in proline level, together with decreased water potential, and leaf osmotic potential. However, SeNPs increased growth attributes, chlorophyll content, total soluble sugars, leaf relative water content, and gas exchange parameters in treated plants which were conversely decreased by Cd toxicity. The seeds priming with SeNPs promoted antioxidant response by increasing catalase (CAT), ascorbate peroxidase (APX) and peroxidase (POX) activity and safeguarding cellular structures through scavenging free radicals and reactive oxygen species. Furthermore, Cd stressed plants displayed an upper level of MDA (1.91 fold) while SeNPs improved membranous integrity through detoxification of hydrogen peroxide. Additionally, SeNPs enhanced nutrients contents (P, K, Ca, Mg, Zn), metal tolerance index and diminished Cd content in plants resulting in the improved growth and development of Cd affected coriander plants.

The Foliar Spray Application of Selected Organic Fertilizers and Their Effects on Selected Plants

Fertilizers are any organic or inorganic natural or synthetic materials [other than liming materials], which is applied to a soil to provide one or more plant nutrients necessary for plant growth. One of the most extreme conditions that have a detrimental impact on the climate is sandy soil. The use of different organic amendments is a tool for developing sustainable development that is both economically and environmentally viable. The aim of this study is to see how milk tea waste extract, banana peel extract and coconut peat extract affect the growth of coriander and spinach plants when applied as a foliar spray. Different pots for various organic fertilizers were used. In this study we discussed how they affected plant growth and how they improved the biochemical properties of sandy soil. The different concentration (2g, 4g, 6g) of banana peel powder, milk tea waste powder and coconut peat were used in this study. The result showed that the highest plant height, root height, number of leaves and shoot height was found in 4g milk tea waste powder in both plants spinach and coriander compared to other fertilizers and control plant. This observation is suggested that the use of milk tea waste is feasible amendment strategy for improving the growth and soil fertility quality of sediments.

Improving secondary metabolite accumulation, mineral content, and growth of coriander (Coriandrum sativum L.) by regulating light quality in a plant factory

ABSTRACTA plant factory with artificial lighting is an advanced indoor cultivation system that has been being developed rapidly for producing high-quality vegetables in many countries. Coriander is an important herbal vegetable and contains abundant secondary metabolites, vitamins, and minerals, which are essential for human health. Five different light qualities, red (R), blue (B), green (G), red:blue (RB, ratio of 87:13), and red:blue:far-red (RBFr, ratio of 81.5:12.5:6) were applied to identify the optimal light quality for enhancing the growth and accumulation of minerals and bioactive metabolites in coriander. Results showed that biomass, chlorophyll index, and ascorbic acid content of coriander plants were significantly higher in RB or RBFr light treatments than in other light treatments. The antioxidant capacity and total phenolic content were the highest under B light. The total phenolic content per plant was the highest under RBFr light due to the high growth rate and biomass production of the plants. Besides, tipburn occurrence in coriander was not affected by total Ca content in the shoot. RBFr was found to be the optimal light spectrum for producing coriander with high yield and contents of ascorbic acid, total phenolics, Ca, and P in a plant factory.

Foliar Application of Thiamin Stimulates the Growth, Yield and Biochemical Compounds Production of Coriander and Fenugreek

Abstract This study was aimed to investigate the effect of thiamine (Th) foliar application on some morpho-physiological aspects in coriander and fenugreek. Three levels of Th (250, 500 and 750 ppm) plus control treatment (distilled water) were studied under controlled greenhouse conditions. All the levels of Th, in particular the concentration of 500 ppm, increased the vegetative growth of coriander. 1000-grain weight, contents of nitrogen and phosphorus, carotenoid and chlorophyll b contents were the highest at a concentration of 750 ppm. Fenugreek vegetative growth also responded positively to the application of Th especially at a concentration of 750 but also 500 ppm increased the content of leaf nitrogen, chlorophyll b, carotenoids, phenolics and antioxidant activity. Overall, the performance of coriander and fenugreek was improved by the application of Th foliar at all levels.

Effects of manure-based urea pellets on growth, yield, and nitrate content in coriander, garden cress, and parsley plants

ABSTRACTVarious organic residues and animal manures represent an excellent matrix material for production of natural-based pellet fertilizers. Fully decomposed cow manure with 50% w/w urea was used for pellet production in densities of 400 or 800 kg/m3, representing low and high compact urea pellets. The growth of coriander (Coriandrum sativum L.), garden cress (Lepidium sativum L.), and parsley (Petroselinum crispum Mill.) were then evaluated under application of these pelleted urea compared to urea alone and unfertilized plants. The total amount of applied nitrogen (N) in the form of urea or pelleted urea was 300 mg/kg soil, wherein pelleted urea treatments, 30% of N was incorporated into the soil as urea alone before planting. The results showed that application of pelleted urea in low and high compactness resulted in different plant responses in the three vegetable crops. Plant growth and biomass production was increased in plants treated with urea or low compact urea pellets. Leaf N concentration and the Soil-Plant Analysis Development (SPAD) index were increased by low but not by high compact urea pellet application. Regardless of compactness, pellet treated plants had less nitrate content compared to urea treated plants. Number of flowering plants in coriander and garden cress was higher with high compact urea pellet and in unfertilized plants, whereas plants treated with urea or with low compact urea pellet showed fewer flowering plants. So, for production of these leafy vegetables low compact pellet is preferred.

Comparative assessment for the effects of reactive species on seed germination, growth and metabolisms of vegetables

Abstract Reactive oxygen and nitrogen species (RONS) play an important role as signaling molecules in various biological pathways in plants. The aim of this study is to assess the effects of H 2 O 2 (ROS) and nitric oxide (RNS) on seed germination, seedling growth and metabolism of two vegetables, coriander and carrot. Seed germination and seedling length of vegetables were significantly increased after treatment with H 2 O 2 for 12 and 24 h. An optimal concentration of H 2 O 2 giving maximum effect was 25–50 mM for both vegetables. The seed germination and seedling growth of coriander were significantly increased after treatment with 12.5 and 25 μM sodium nitroprusside (SNP; generating about 10–25 μM NO) for 12 and 24 h. On the other hand, SNP treated carrot seeds showed no significant difference in seed germination, compared to control. Amounts of total soluble proteins extracted from both vegetables at 72 h post-germination were significantly greater in treatment with 25 mM H 2 O 2 . Amounts of total soluble proteins were significantly increased in coriander seeds treated with SNP during germination but not in carrot. The α-amylase activity measured as the amount of reducing sugar was significantly increased in coriander and carrot after H 2 O 2 treatment. Our results suggest that the effect of RONS on seed germination, growth and development, and seed metabolisms can be various depending on dose and plant species.

Changes in growth, chlorophyll content and grain yield of Coriander (Coriandrum sativum L.) in response to water stress, chemical and biological fertilizers and salicylic acid

Salicylic acid (SA) is a phyto-hormone that regulates physiological and biological processes in plants and can be used to improve plant growth under different environmental conditions, including water stress. Thus, a field experiment as split plot factorial based on randomized complete blocks design with three replications was conducted in 2014 to investigate the effects of fertilizer and salicylic acid on growth, chlorophyll content and grain yield of coriander (Coriandrum sativum L.) plants under drought stress. Treatments were three levels of water supply (irrigation after 60, 90 and 120 mm evaporation from class A pan) and four levels of fertilizer application (control, 100 kg ha-1 Urea, Nitrokara (biofertilizer) and 50% Urea + Nitrokara) and foliar spray of salicylic acid (0 and 1 mM). Results indicated that water deficit had a significant reduction effect on leaf area, chlorophyll content, fresh weight of root and leaf and grain yield. Salicylic acid and 50% Urea + Nitrokara resulted in a significant increase of all traits under stress and well watering conditions. Although highest amount of studied traits was observed in plants treated with SA or application of 50% Urea and Nitrokara under well watering, but the changes rate was higher under stress conditions. Therefore, salicylic acid and combination of urea and Nitrokara can be used to promote growth of coriander under different water availabilities, which ultimately can enhance field performance of this plant.

Effect of Salinity Stress on Coriander (Coriandrum sativum) Seeds Germination and Plant Growth

A pot experiment was carried out to study the effect of salinity stress on seeds germination and plants growth of Coriander (Coriandrum sativum L.)by the selection method. For this purpose, four treatments of different concentrations of NaCl were used, namely, 0, 1000, 2000, 3000, and 4000 ppm of NaCl. The following parameters of: seeds germination, roots number and length, plant strength, number of leaves, plant length, shoot tip necrosis, and the percentage of survivals were recorded. The Obtained results showed that all growth parameters were reduced by increasing the NaCl concentration except for the percentage of shoot tip necrosis which was increased with a significant difference among all treatments. Coriander plants were found to resist salinity up to the concentration of 3000 ppm NaCl only.
