“…Seed primed with -0.5 MPa for 6 hours recorded highest shoot length (19.53 cm in between paper method and 20.63 cm in sand method), while lowest shoot length (15.10 cm in between paper method and 17.20 cm in sand method) (Table 2 and 3) was noticed with the seed primed with 0 MPa for 24 hours. Increase in shoot length due to osmopriming with PEG was also reported earlier in common bean (Amanpour-Balaneji and Sedghi, 2012) and chickpea (Khadraji et al, 2017). Lee and Kim (2000) found that priming increased the metabolic activities of seed ultimately resulting in substantial increase in shoot length than non-primed seed.…”

“…Among the interaction of concentration and duration of priming, seed priming with -0.5 MPa PEG for 6 hours recorded highest root length (17.05 cm and 16.19 cm in between paper and sand methods, respectively) and 0 MPa for 24 hours recorded lowest root length (10.78 cm and 11.28 cm in between paper and sand methods, respectively) (Table 2 and 3). Increased root length by osmopriming with PEG was also earlier reported in chickpea (Khadraji et al, 2017). Faijunnahar et al, (2017) concluded that the considerable increase in root length in the primed seeds of wheat might be due to increased metabolic activities in the primed seeds than non-primed.…”

To standardize the best concentration and duration of osmopriming of aged seed of chickpea variety, NBeG-3 with Polyethylene Glycol, an experiment was conducted in Factorial Completely Randomized Design with four replications. The seed was subjected to osmopriming with different concentrations of PEG 6000 viz., 0, -0.5, -1.0, -1.5 and -2.0 MPa for various durations viz., 3, 6, 9, 12 and 24 hours. The seed quality was assessed by testing for germination in between paper method and sand method. In both the methods of testing, concentration of PEG, duration of osmopriming and their interaction exhibited highly significant effect on germination, seedling length and seedling vigor index. Among all the concentrations used, seed primed with -0.5 MPa PEG recorded highest germination, root length, shoot length, seedling length, root / shoot ratio and seedling vigor index. Among the various durations, osmopriming for 6 hours showed highest improvement in seed quality. The interaction effect of seed priming with -0.5 MPa PEG for 6 hours also showed highest improvement in seed quality attributes.

“…In the case of chick pea crop, the activity of peroxidase is also observed by (Mafakheri et al, 2011;Kaur et al, 2013;Khadraji et al, 2016). According to their findings, higher concentration of ascorbic acid is minimized by the activity of peroxidase which function as a defensive system for the plant.…”

D rought effects are commonly related to the agriculture and water resource sectors. They may cause substantial economic losses in the agriculture sector of developed countries through reductions in crop yield or total failure of crops (Sweet et al., 2017;Tian et al., 2018). Under certain circumstances they can also cause human migration and famine in developing countries (Gray and Mueller, 2012; Abstract | Extreme climatic conditions like heat waves, dry spell, sustained drought and precipitation adversely reducing the crop productivity and these are considered as an alarming issue for the crop production in rainfed areas. Chick pea is deemed to be regarded as a drought sensitive crop. The low water and fertilizer demand and its ability to grow on marginal land is an excellent choice for the farming community. The field trial was conducted with the aspect to screen out the drought-tolerant variety of chick pea keeping in view the physiological and biochemical attributes under drought conditions. Drought stress adversely reduced the vegetative growth in term of primary branches, secondary branches and pod yield. Based on biochemical, morphological and physiological parameters a significant difference was observed among the genotypes. Out of twenty-five genotypes, three chick pea genotypes i-e chick pea genotypes GGP1260, GGP1426 and PB01 shown the best drought tolerance efficiency (83.78, 84.21 and 81.57%), harvest index (83.23, 84.06, and 81.14%) and minimum reduction in pod yield (16.21, 15.78 and 18.42%) under rainfed controlled conditions. Under rainfed condition the activity of all enzymes increased among all genotypes. The chick pea genotypes, GGP-1260, PGP-1426 and PB-1 were observed as drought-tolerant ones on the basis of biochemical, morphological and physiological parameters and these can be recommended for rain-fed areas crop selection.

“…Our results showed that the total proteases and α-amylases in the seeds exhibited a significant decline in activity with increasing drought stress (Figure 4). Previous reports showed that under water stress α-amylase activity were affected in Cicer arietinum cotyledons and in Medicago sativa germinating seeds (Hamidi and Safarnejad, 2010;Khadraji et al, 2017). Furthermore, seed priming was found to enhance the α-amylase and total proteases activities in all sorghum varieties.…”

Seeds of three sorghum (Sorghum bicolor (L.) Moench.) varieties from Southwest Saudi Arabia were used to investigate the potential of osmopriming with polyethylene glycol (PEG 8000) to improve germination performance, seed reserve utilization and early seedling growth and drought stress tolerance. The primed (PS) and unprimed (UPS) seeds of the three sorghum varieties were germinated for 8 days under increasing PEG-induced osmotic stress. The treatments were arranged in a completely randomized design, in a factorial arrangement, with three sorghum cultivars (‘Zaydia’, ‘Shahbi’ and ‘Ahmar’) and four osmotic potentials (0.0; -0.4; -0.8 and -1.2 MPa) with four replicates of 50 seeds each. The results showed that drought stress affected seed germination and seedling emergence and establishment, but increased the activity of the antioxidant enzyme catalase (CAT). The strongest inhibition of germination and growth occurred at the highest PEG concentration and a significant difference was noticeable between the studied varieties. We confirmed also that seed osmopriming improved seed germination performance, seedling growth and enhanced the CAT activities while reduced malonyldialdehyde (MDA) accumulation and electrolyte leakage (EL) in the drought-stressed seedlings. Seed priming have enhanced also the α-amylase and total proteases activities in all varieties. The largest increase of these hydrolysing enzymes was shown in ‘Ahmar’. Furthermore, the PEG priming lead to improvement of the weight of utilized (mobilized) seed reserve (WUSR), seed reserve depletion percentage (SRDP) and total seedling dry weight (SLDW) of sorghum seedlings under water stress conditions. Still, the highest values or all three parameters were found in the ‘Ahmar’ variety. Under increasing drought stress conditions, ‘Ahmar’ showed the highest yield stability index (YSI) and the least EL and MDA contents in comparison to the other two varieties during the seedling establishment stage. Therefore, the former variety can tolerate better a rigorous water stress condition. ‘Zaydia’ appears to be the most vulnerable to drought stress. Thus, the use of species or varieties with eminent seed metabolic quality is an advantageous trait in drought-prone regions.
