“…Eustress with H 2 O 2 increased the activity of this enzyme in both cultivars over salinized plants. Çavusoglu and Kabar [34], Gondim et al [50] and Santhy et al [51] have apprised that pretreatment of H 2 O 2 increased the activity of CAT enzyme in plants in response to salt stress and enhanced salt tolerance in plants. In this study, POD activity increased under seawater stress in Misr 1 and decreased in Gemmiza 11 in the same situation.…”

In this study, the positive role of hydrogen peroxide (H2O2) pretreatment in mitigating the adverse impacts of seawater stress has been evaluated in two wheat (Triticum aestivum L.) cultivars, namely Gemmiza 11 as a salt-sensitive and Misr 1 as a salt-tolerant cultivar, with contrasting phenotypes in response to the salinity stress. Under normal conditions, wheat seeds eustress with H2O2 have shown significant effects on the improvement of plant growth parameters, such as dry weight and root and shoot lengths. Under salt stress conditions, seeds eustress with H2O2 have shown a reduction in damage to plant growth and physiological parameters as compared to the seeds kept as un-primed in both wheat cultivars. In addition, eustress of seeds with H2O2 has induced an increment in the pigments content, proline level and mineral uptake (K+, Ca2+ and Mg2+). Moreover, seeds eustress with H2O2 have shown significant decrement in Na+ content uptake in plants and that subsequently reduced lipid peroxidation. Seawater stress has increased the activity of the antioxidant system based on catalase (CAT), peroxidase (POD) and ascorbate peroxidase (APX) in both cultivars, except POD in Gemmiza 11. Similarly, the application of H2O2 has further enhanced the activity of the antioxidant system in stressed plants and this enhancement of the antioxidant system further reduced Na+ content in plants and subsequently increased the growth parameters. Results of inter-simple sequence repeat (ISSR) markers have shown clear differentiation among the treatments and have provided strong evidence in support of the hypothesis proposed in this study that H2O2 eustress improves seed tolerance and enhances plant growth parameters under seawater stress.

“…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.
