“…Seed priming is a simple, low-cost, and effective strategy for enhancing crop performance [ 9 ]. It is described as a physiological approach that involves hydration and drying of seeds to improve the pre-germinative metabolic process without radicle protrusion in water or solution of other priming agents [ 10 – 12 ]. Many agricultural and horticultural crops have been shown to benefit from it in terms of seed germination and seedling establishment and ultimately the productivity [ 13 – 17 ].…”

The yield and quality of an annual crop are highly dependent on uniform and rapid germination of the seeds. In case of bitter gourd (Momordica charantia), the germination and field emergence is always a problem as seeds have thick and hard seed coat. Pre-sowing hydro-priming is one of the most suitable, affordable, easily available, and cost-effective techniques in breaking down seed dormancy to enhance germination. Hence, a field experiment was conducted in Surkhet district of Nepal 2020 to assess the effect of different hydro-priming duration on germination and seedling growth of bitter gourd. The experiment was laid out in single factor Randomized Complete Block Design (RCBD) with four replications and seven treatments including different hydro-priming durations (T0: control, T1: 6 hours, T2: 12 hours, T3: 18 hours, T4: 24 hours, T5: 36 hours and T6: 48 hours) of bitter gourd seeds of Palee variety, the most popular variety among the farmers. The highest water uptake and germination were found in 48 hours of seed hydro-primed seeds whereas the lowest water uptake and germination were observed on non-primed seeds. Similarly, the tallest seedling, most vigorous seedling in terms of seedling vigour index I and II was observed in 48 hours hydro-primed seeds followed by 36 hours of seed hydro-priming and shortest seedling and the least vigorous seedling in control. Thus 48 hours of seed hydro-priming was found to be effective for increasing germination and seedling growth in bitter gourd, which needs to be further investigated under large, open-field conditions with different varieties.

“…The present study revealed that the high vigour seeds of chickpea and lentil were having the highest germination percentage as well as a good antioxidant defense mechanism. The quality of mid vigor and low vigor seeds may be enhanced using several seed priming methods [11,21]. Seed priming will help to enhance the quality of seeds and further for the successful crop establishment in order to obtain higher production.…”

The present study was conducted to evaluate the seed quality of chickpea (cv. PG-186) and lentil (cv. HUL-57) seed samples collected from randomly selected districts of different agroclimatic zones of Bihar. The seed quality was assessed based on their physiological (seed moisture, seed germination, seedling length, vigour index, etc.) and biochemical enzymes (SOD, POX and CAT) parameters. Based on the physiological and biochemical evaluation, the chickpea seed sample collected from the Sheikhpura district was found significantly high quality (96.3% germination percentage) among all, while seeds collected from Begusarai (76.7%) and Darbhanga (77.7%) districts exhibited lowest germination percentage. The germination and vigour of lentil seed revealed that the sample of Patna district was having the highest germination percentage (98.7%) while seeds collected from Katihar and Rohtas district exhibited lowest germination percentage (66% and 74.3% respectively). In the case of biochemical analysis of both chickpea and lentil seed samples, higher SOD, POX and CAT activities were observed in seeds in which the highest germination percentage was recorded. On the basis of the results of chickpea and lentil seed samples, the seed lots were categorized into high, mid and low vigour. Among chickpea, the seed samples of Sheikhpura, Patna, Munger, Bhagalpur, Lakhisarai, and Jehanabad were categorized as high vigour; while seeds of Darbhanga and Begusarai district were categorized as low vigor. Similarly, in case of lentil the seed samples of Patna, Munger, Bhagalpur, Sheikhpura, Lakhisarai, and Khagaria were categorized as high vigour; while seeds of Rohtas and Kathiahr district were categorized into low vigor. This study will be helpful to the farmers and pulses growers in order to enhance the seed quality for getting higher production in respective districts.

“…Priming and elicitation are strongly recommended ecofriendly agricultural approaches for agricultural production under actual global climate change (123). A number of agents, such as cold, drought, water, inorganic salts, sugars, solid medium with water and various nutrients, beneficial microbes, micronutrients, hormones (JA, MeJA, SA, and ABA), rhizobacteria, as well as organic sources (112,(124)(125)(126)(127)(128), are used for fruit and vegetable seed priming. Discrepant conclusions are drawn regarding the effect of NaCl for different broccoli cultivars even when the same treatments are applied.…”

Pre- and Post-harvest Factors Affecting Glucosinolate Content in Broccoli

et al. 2020

View full text Add to dashboard Cite

Owing to several presumed health-promoting biological activities, increased attention is being given to natural plant chemicals, especially those frequently entering the human diet. Glucosinolates (GLs) are the main bioactive compounds found in broccoli (Brassica oleracea L. var. italica Plenck). Their regular dietary assumption has been correlated with reduced risk of various types of neoplasms (lung, colon, pancreatic, breast, bladder, and prostate cancers), some degenerative diseases, such as Alzheimer's, and decreased incidence of cardiovascular pathologies. GL's synthesis pathway and regulation mechanism have been elucidated mainly in Arabidopsis. However, nearly 56 putative genes have been identified as involved in the B. oleracea GL pathway. It is widely recognized that there are several pre-harvest (genotype, growing environment, cultural practices, ripening stage, etc.) and post-harvest (harvesting, post-harvest treatments, packaging, storage, etc.) factors that affect GL synthesis, profiles, and levels in broccoli. Understanding how these factors act and interact in driving GL accumulation in the edible parts is essential for developing new broccoli cultivars with improved health-promoting bioactivity. In this regard, any systematic and comprehensive review outlining the effects of pre-and post-harvest factors on the accumulation of GLs in broccoli is not yet available. Thus, the goal of this paper is to fill this gap by giving a synoptic overview of the most relevant and recent literature. The existence of substantial cultivar-to-cultivar variation in GL content in response to pre-harvest factors and post-harvest manipulations has been highlighted and discussed. The paper also stresses the need for adapting particular pre-and post-harvest procedures for each particular genotype in order to maintain nutritious, fresh-like quality throughout the broccoli value chain.
