“…But the affect of Proline 10mM and ascorbic acid 4mM was more as compared to proline 5mM and ascorbic acid 1mM respectively as showed in figure(1). Germination percentage declined with the increase in salinity levels (Hemalatha et al, 2017). Proline has an important role in increasing germination and it also increases resistance to various stresses (Kaur et al, 2015).…”

“…High levels of salt in soil causes imbalance in osmotic potential, ionic equilibrium and nutrient uptake (Nawaz et al, 2010). Salinity stress reduce plant yield by affecting physiology as well as biochemistry of plant (Hemalatha et al, 2017). Excess amount of salt adversely affects plant growth and development and decreases yield and crop productivity (Manaa et al, 2011).…”

“…Seed priming with H 2 O 2 having the capacity to enhance the multi-resistance to heat, drought, chilling and salt stress in rice (Uchida et al, 2002) [61] . Likewise, seed priming with Hydrogen Peroxide @ 0.25% reduced the effect of salt stress in rice even under higher salt concentrations (Hemlatha et al, 2017) [22] . BABA priming of rice seeds improved the drought and salinity stress tolerance.…”

Plants are exposed to any number of potentially adverse environmental conditions such as water deficit, high salinity, extreme temperature, submergence, etc. These abiotic stresses adversely affect the plant growth and productivity. Seed priming is an easy, low cost and low risk method for improving growth and development of plants especially under adverse environmental conditions. Seed priming has been developed as an indispensable method to produce tolerant plants against various stresses in rice. The beneficial effects of seed priming include faster emergence, better stands, and lower incidence of resowing, more vigorous plants, better drought tolerance, earlier flowering, earlier harvest and higher grain yield. These beneficial effects of seed priming are due to several reasons such as activation of enzymes associated with endosperm utilization and seed germination, mobilization of storage proteins, changes in hormonal balance and synthesis of proteins that play an important role during seed germination. Seed priming emerges as a promising technology for combating abiotic stress in crops and alleviating the detrimental effects of abiotic stress without much affecting its fitness. Seed priming methods are widely used as an emerging technology to produce tolerant crop varieties against abiotic stresses.

“…Seed priming seems to be cost-effective and easy to be used by farmers method to increase germination rate and stress resistance of various crops (Jiménez-Arias, Carrillo-Perdomo, Gracía-Machado, Jorge, & Borges, 2017). It was shown that priming of, for example, maize (Zea mays L.), cotton (Gossypium hirsutum L.) or rice (Ahmad et al, 2012;Hemalatha, Renugadevi, & Eevera, 2017;Santhy, Meshram, Wakde, & Vijaya Kumari, 2014) seeds with H 2 O 2 increases their vigour. However, no data on the effect of priming with hydrogen peroxide on B. napus seed vigour were shown so far.…”

Germination is a crucial process in crop plant life cycle that determines future yield. Hydrogen peroxide plays a significant role in both dormancy release and seed ageing. The potential of the rapeseed metallothioneins (BnMT1‐4) as reactive oxygen species scavengers was investigated. In the presence of H2O2, bacterial cells expressing BnMT1‐4 had higher growth rate than control cells. However, such effect was not observed in an oxidative stress oversensitive yap‐1Δ yeast mutant strain expressing BnMT1‐4. Next, it was shown that H2O2, up to 100 and 10 mM, promotes rapeseed germination rate and seedling growth, respectively. Moreover, it was demonstrated that in seeds germinating in the presence of H2O2, the expression of seed‐specific BnMT4 decreases to a high extent in a dose‐ and time‐dependent manner. It was shown that the decline in BnMT4 mRNA level, accelerated by up to 10 mM H2O2 treatment, correlates positively with increased rapeseed germination and early growth, underscoring the plausible role of BnMT4 as a H2O2 scavenging protein that level has to be downregulated in conditions where the compound is needed. Finally, it was demonstrated that H2O2 could be used as a priming agent of rapeseeds.
