“…In similar ndings, it was hypothesized that the extra peptide could be a peptide of 2S albumin with Mw 4-10 kDa 49 . Similar trends were reported in cucumber 35 and black beans 50 . The probable reason for the extra one band in all treated seeds is priming, resulting in the synthesis of lost proteins and some new ones.…”

Chickpea is a highly nutritious protein-rich source and one of the major crops to alleviate global malnutrition. It is the third-largest legume cultivated globally in arid and semi-arid environments. Chickpea productivity is affected by several factors, among which poor seed quality is one of the significant factors contributing to its decrease in productivity. Seed quality is essential for better crop establishment and higher yields, particularly in the uncertain climate change. The present study investigated the role of botanical priming in enhancing seed quality by investigating physio-biochemical responses and crop performance in chickpeas. The study compared the effects of botanical priming with hydropriming, seed treatment with bavastin and control on medium-vigour chickpea seeds. A detailed physiological (germination percentage, root and shoot length, vigour index) and biochemical (amylase, protease, dehydrogenase, phytase, and lipid peroxidation) analysis was carried out in the laboratory to assess the effect of priming treatments. SDS-PAGE was used to compare seed storage protein expression in primed and control seeds. Seeds treated with 1% turmeric leaf extract displayed a higher germination rate (94.5%) than the control and other priming treatments. Turmeric-primed seeds showed higher seedling length, vigour index, enzyme activity, and lower MDA content. SDS-PAGE analysis revealed the expression of two minor polypeptides of the albumin and three minor polypeptides of the globulin subunit. Moreover, field experiments indicated increased crop growth, vigour, and days to 50% flowering, yield and its attributing traits in turmeric-primed seeds. The study demonstrates that botanical priming can increase the yield of chickpeas by up to 16% over the control group. This study proves that implementing low-cost and eco-friendly seed priming techniques can significantly enhance the genetic potential of chickpeas by improving their physiological and biochemical activities during seed germination and crop growth. Therefore, chickpea growers must adopt botanical priming techniques to improve seed quality and crop performance. This study unequivocally establishes the efficacy of botanical priming as a powerful tool for augmenting chickpea growth. Moreover, this approach is environmentally sustainable and can help conserve natural resources long-term. Therefore, this new approach must be widely adopted across the agricultural industry to ensure sustainable and profitable farming practices.

“…( 2002) and ( 2009) reported that hydropriming treatment can be successfully applied to watermelon and cucumber seeds to improve germination performance, respectively. Primed seeds further exhibited tolerance to abiotic stress conditions (high temperature and water stress) as evident from higher germination compared to unprimed (Pandey et al, 2017).…”

Poor seed germination obstructs the early and uniform seedling emergence at the sub-optimal conditions which can be a major setback to early spring cucumber growers. Different seed priming methods ought to be efficient solutions for the problem. To standardize the best priming method, an experiment was laid out in a Completely randomized design at the Horticulture lab of IAAS, Lamjung Campus. The treatment consisted of demineralized distilled water (hydropriming), hormonal priming (GA3 100ppm and GA3 200 ppm), halopriming (NaCl 0.5% and KNO3 0.5%), and non-primed seeds as control. The seeds were soaked in the respective treatment for 24 hours and then dried to initial moisture content under shade conditions. Observation recorded significantly highest germination percentage in GA3 100ppm (19.25%) and hydro priming (19.25%). The lowest mean germination time was found in GA3 100ppm (4.19days) which was significantly at par with GA3 200ppm (4.33days) and hydro priming (4.48days). The germination energy was found highest in GA3 100ppm (39.58) followed by GA3 200ppm (33.65) and dry weight was recorded highest in hydropriming (0.0252g) followed by GA3 100ppm (0.0250g) whereas the highest root length was observed in KNO3 priming (12.955cm) which is statistically at par with hydropriming (11.42cm), GA3 200 ppm (10.872cm) and NaCl priming (10.42cm). The plumule length was observed highest in KNO3 (13.00cm) followed by NaCl (11.25cm). All primed seeds showed increased seedling vigor compared to the unprimed seeds. The study showed that applied treatment notably increased the germination characteristics and seedling stand.

Efeito do extrato de Ascophyllum nodosum na germinação de sementes de couve em diferentes temperaturas

et al. 2021

A temperatura é um fator que interfere diretamente na capacidade germinativa de sementes. Com as elevações de temperaturas ocasionadas pelo aquecimento global, assim como em situações de cultivo protegido de plantas em ambientes tropicais e subtropicais, é necessário estudar procedimentos que possam contribuir para aumento da tolerância a temperaturas que causam estresse e alteração em processos fisiológicos. Desta forma, o objetivo desse trabalho foi avaliar o efeito do condicionamento fisiológico de sementes de couve com diferentes doses de extrato da alga marrom Ascophyllum nodosum na germinação e crescimento de plantas em diferentes temperaturas. Realizou-se o experimento em delineamento experimental inteiramente casualizado, com esquema fatorial 2 x 4 (temperaturas x doses), com cinco repetições. Os tratamentos consistiram das doses de 0; 0,25; 0,50; 1,0 ml. L-1 de extrato da alga marrom Ascophyllum nodosum. O efeito dos tratamentos foi avaliado por meio de: porcentagem e velocidade de germinação, comprimento e massa seca da parte aérea e de raízes de plântulas, em condições de temperatura ideal (20°C) e de estresse (30°C). O condicionamento de sementes de couve com extrato da alga marrom Ascophyllum nodosum não interfere na germinação de sementes, tanto em condição ideal quanto em temperatura elevada (30°C); o condicionamento de sementes de couve com as doses de 0,67 e 0,25 mL.L-1, promove maior crescimento de raízes de plântulas, nas temperaturas de germinação de 20 e 30°C, respectivamente, contudo, não promove incrementos no crescimento de parte aérea e no acúmulo de massa seca total de plântulas.
