“…Many different methods are used as seed priming techniques such as hydro-priming, halopriming, solid matrix priming, osmo-priming, nutria-priming, hormonal priming and biopriming. Many researchers have reported that plant growth, tolerance to stress factors, stand establishment and productivity of crops can be improved by seed priming (Farooq et al, 2017;Reis et al, 2018;Haider et al, 2020;Maurya et al, 2020). Salicylic acid (SA) is commonly used as hormonal priming on different grain legumes such as lentil (Azarnia et al, 2016), faba bean (Bouallegue et al, 2017), common bean (Mohtashami et al, 2016), cowpea (Pakmehr et al, 2011, and pea (Farooq et al, 2007), therefore, reported to increase plant growth, seed yield, and tolerance to stress factors.…”

Salinity is a global problem that threatens chickpea (Cicer arietinum L.) cultivation in all stages from germination to maturity. Also, salt-affected areas in the World are increasing by the day. Germination is one of the primary stages affecting plant growth and seed yield. Thus, germination performance of seeds has a vital role in vegetative and productive stages. Seed priming, a cheap and easily applicable technique, improves the germination performance by regulating enzymatic reactions and controlling water intake. Seed priming is controlled hydration of seeds soaked in a solution that has low osmotic potential to start the germination metabolism without elongation of radical. The aim of the study was to investigate the effects of different priming treatments on germination traits of chickpea under saline conditions. Three levels of salinity (control, 50 mM and 100 mM NaCl) and 5 priming treatments (nonprimed, hydro-priming, 0.1 mM, 0.2 mM and 0.3 mM salicylic acid) were used in the study. Germination percentage (GP), mean germination time (MGT), germination rate (GR), germination index (GI) and coefficient of uniformity of germination (CUG) were varied between 80.7-98.3%, 1.40-2.67 day, 38.1-75.7, 37.5-72.5 and 0.3-0.7, respectively. Although all treatments caused significant positive effects, the 0.2 mM SA mostly improved the germination traits in the study. Also, it was determined that 0.2 mM salicylic acid priming is the threshold for chickpea and higher concentrations have inhibitory effects on the germination process. Nohut Çimlenmesi Üzerine Tuzluluk Stresinin Salisilik Asit Priming ile AzaltılmasıAnahtar kelimeler: Hidro-priming, osmopriming, iyon toksisitesi, stress azaltma, çimlenme üniformitesi Özet. Tuzluluk, nohut (Cicer arietinum L.) tarımını çimlenmeden olgunluğa kadar her aşamada tehdit eden küresel bir sorundur. Ayrıca, yeryüzünde tuzluluktan etkilenen alanlar giderek artmaktadır. Çimlenme ürün kalitesini ve tane verimini etkileyen evrelerin başında gelir. Bu nedenle, tohumların çimlenme performansları vejetatif ve generatif gelişim dönemleri açısından hayati önem taşımaktadır. Ucuz ve kolay uygulanabilir bir teknik olan priming, su alımını kontrol ederek ve enzimatik reaksiyonları düzenleyerek çimlenme performansının artmasını sağlar. Priming, düşük osmotik potansiyele sahip bir çözeltidebekletilerek tohumun çimlenme metabolizmasının kökcük çıkışı olmaksızın başlatıldığı kontrollü su alımını ifade eder. Çalışmanın amacı, tuzluluk stresi altındaki nohutta farklı priming uygulamalarının çimlenme özellikleri üzerine etkilerini belirlemektir. Çalışmada 3 tuzluluk seviyesi (kontrol, 50 mM NaCl ve 100 mM NaCl) ve 5 ekim öncesi uygulama (kontrol, hidro-priming, 0.1, 0.2 ve 0.3 mM salisilik asit) kullanılmıştır.Çimlenme yüzdesi (% 80.7-98.3), ortalama çimlenme süresi (1.40-2.67 gün), çimlenme hızı (38.1-75.7), çimlenme indeksi (37.5-72.5) ve çimlenme üniformluk katsayısı (0.3-0.7) değerleri , , ve Belirlenmiştir.Çalışmadaki tüm uygulamalar önemli pozitif etkilere sebep olmasına rağmen 0.2 mM SA uygu...

“…Most importantly, NSP was very cost-effective, with net benefit-to-cost ratios of 75 for wheat and 780 for chickpea observed. Similarly, Haider et al (2020) observed improved grain yield and grain content following seed priming with 0.01M Zn and 0.05M Zn solution as contrast with control. In another study, Zulfiqar et al (2020) demonstrated that Fe seed priming was the most effective method in improving the grain yield and benefit-cost ratio in conventional and zero tillage systems in comparison to soil and foliar application.…”

Micronutrient deficiency is a major constraint to crop productivity in South Africa. Agronomic interventions such as nutrient seed priming (NSP) could significantly improve stand establishment in micronutrient deficient soils. However, the effectiveness of the technique depends on the efficacy of the priming procedures. Laboratory and glasshouse studies were carried out to determine the effects of NSP concentration of Zn, B and Mo and priming duration on maize germination and seedling emergence and early growth in micronutrient deficient soils. Five concentrations: 0.01%, 0.05%, 0.1%, 0.5% and 0% (control) and three priming durations: 24 h, 12 h and 8 h were used for the laboratory experiment whilst the 0.5% concentration and 8 h duration were excluded in the glasshouse experiment. Seed priming duration and concentration levels and their interactions had significant (P < 0.05) effects on germination percentage (GP), germination rate (GR), the coefficient of velocity of germination (CVG), days to germination (DG) and mean germination time (MGT). These parameters were improved by priming at low concentration of the micronutrients for longer. Similarly, under glasshouse conditions, NSP at the lowest concentration but for the longest duration resulted in up to 50% earlier seedling emergence over the control. Priming with 0.01% Bo reduced the number of days to seedling emergence by 94%, increased fresh and dry seedling mass and chlorophyll content index by 29%, 47% and 58% respectively relative to the control. The earlier seedling emergence could have also contributed to superior fresh and dry seedling mass as well as both higher shoot and root mass over the control. Moreover, NSP enhanced chlorophyll content index, which could have ultimately led to better shoot growth. This suggests that with optimum micronutrients concentration levels and appropriate priming duration NSP can improve germination and seedling growth and hence maximization of the yield parameters.

Cadmium (Cd) inhibits plant growth, perturb nutrient uptake and affect chloroplast ultra structure. Cd soil pollution is mainly contributed by excessive use of phosphate fertilizers, nickel Cd batteries, plating and sewage sludge. Research investigations deciphering role of Cd in affecting overall performance of mung bean is least understood. Likewise ameliorative effects of gibberellins (GAs) in Cd induced toxicity in mung bean are lesser known. In this context, effects of Cd stress (CdCl2, IC50 −500 µM L−1) with or without GA3 application on mung bean (Vigna radiata L. Var. SML-668) plants were comprehensively investigated under controlled conditions. In brief, a total of 80 mung bean plants (15 days old of uniform height) were divided into four groups, with each group (n=20) subjected to four different treatments (Control, CdCl2, GA3, CdCl2+GA3), twice during the entire life cycle of mung bean plants (until harvest 85-90 days). Results revealed negative impacts of Cd stress on shoot morphometry (plant height, leaf surface area, stem diameter, shoot fresh weight, number of leaves, number of pods, length and diameter of pods), root morphometry (root length, root surface area, root dry weight, nodule number and nodule diameter), photosynthetic pigments and agronomic traits. GA3 ameliorated Cd stress by modulating shoot and root growth rates, improving overall plant metabolism, photosynthetic pigments, and shoot and root morphometry and transcript abundance of VgPCS1, VgPCS2, VgCdR and VgIRT1. Current study proposes GA3 application for the effective management of Cd induced phytotoxicity in mung bean plants.
