“…Nonetheless, the yellow passion fruit tree is very demanding in water terms and sensitive to salinity stress, with a maximum salinity of 1.3 dS m -1 (Ayers & Westcot, 1999;Mesquita, Rebequi, Cavalcante, & Souto, 2012). Ergo, this behavior at the concentration of 5 μmol of H 2 O 2 can mitigate the depressive effect because, according to Kilic and Kahraman (2016), the H 2 O 2 reduced the salt-induced inhibition at germination, reducing the salinity stress' detrimental effects in the development of barley plants induced to pre-germinative treatment with peroxide at 30 μmol.…”

Hydrogen peroxide (H2O2) is a molecule that can flag plants under biotic and abiotic stress conditions. Among the kinds of stress, the salinity stress is the one that most usually affects plants. Consequently, the purpose hereof was to use hydrogen peroxide (H2O2) to mitigate the possible harmful effects of salinity in yellow passion fruit seedlings. We employed a randomized block design, in a 5 × 3 factorial scheme, corresponding to five irrigation water electric conductivity levels (0.3; 1.3; 2.3; 3.3; and 4.3 dS m-1) and three hydrogen peroxide concentrations (0; 5; and 15 μmol L-1), with four repetitions. The treatments were applied foliarly 7 and 15 days after the seedlings’ germination with hand sprayers. Sixty days after sowing, we evaluated the seedlings’ growth and quality variables, which finally proved that hydrogen peroxide mitigates the harmful effect of the irrigation water’s salinity up to 2 dS m-1 in the growth of yellow passion fruit seedlings at the concentration of 5 μmol/L. Nonetheless, excessive concentrations (15 μmol L-1) associated with high salt concentrations were proven detrimental to the seedlings’ phenological growth and quality.

“…The stimulatory effect of H 2 O 2 was described in multiple plant species, including barley (e.g. Kilic and Kahraman, 2016;Ishibashi et al, 2017). Moreover, H 2 O 2 was shown to be involved in co-regulation of α-amylase activation and the programmed cell death in the aleurone cells.…”

Malting of barley grains is a procedure known for centuries, however, the technology of malt production is constantly being studied and optimized. The optimizations comprise different conditions of barley steeping, as well as using different additives to improve seed germination. Among the most famous group of seed germination regulators, gibberellins, a broad spectrum of diverse chemical substances also have stimulatory effects on seed germination. This review summarizes what is known about multiple barley seed germination promoting compounds, as well as other chemical/hormonal seed germination regulators described in other plant species. The goal is to provide an impulse for testing new stimulatory substances with potential applications in malting process optimization.

“…It has great role in signaling several physiological processes like photosynthesis, respiration, transpiration and translocation (Kilic and Kahraman 2016). Furthermore, Wang and Song (2008) explained that abscisic acid increases under drought stress leading to stomatal closure, and according to the relationship between H2O2 and abscisic acid, the latter increases the former in plant cell inducing stomatal closure under stress.…”

“…Furthermore, Wang and Song (2008) explained that abscisic acid increases under drought stress leading to stomatal closure, and according to the relationship between H2O2 and abscisic acid, the latter increases the former in plant cell inducing stomatal closure under stress. Spraying H2O2 on soybean plants helps in maintaining leaf water content and overcoming drought stress problems (Ishibashi et al 2011), induces adaptation to osmotic stress in maize (Terzi et al 2014), enhances barely seed germination and seedling growth under salinity (Kilic and Kahraman 2016).…”

Water deficit is a major growth limitation factor affecting plant growth and productivity. To counteract the harmful effects of drought stress, lupine plants were sprayed with two concentrations of algae extract (1 g L-1 and 2 g L-1) and hydrogen peroxide solution (0.5% and 1%) under low irrigation level. Morphological, physiological and anatomical studies were performed. It was found that all treatments enhanced plant height, root length, number of leaves, average leaf area, shoot and root fresh and dry weights. A significant increment in chlorophyll a and b, carotenoids and total pigments contents, as well as a significant decrease in electrolyte leakage was noted in treated plants compared with untreated under water deficit. Increment in levels of osmoprotectants such as proline, total free amino acids, glycine betaine and total soluble sugars contents was highly significant in case of 2 g L-1 algae extract treatment compared with untreated plants group. Anatomical studies of root, stem and leaf of treated and untreated plants revealed that 2 g L-1 algae extract treatment followed with 0.5% H2O2 induced significant increments in the thickness of the studied plant organs compared with the untreated plants under water deficit conditions. In general, the concentrations of 2 g L-1 algae extract and 0.5% H2O2 were the most effective doses regarding all the studied characteristics.
