Effects of Foliar Application Chitosan and Salicylic Acid on Physiological Characteristics and Yield under Deficit Irrigation Condition

Abstract

Moreover, drought stress increases the amount of abscisic acid in the plant, which reduces the growth rate (Siebeneichler et al., 2020).Research has shown that chitosan consumption is common in living organisms, including plants (Ngo et al., 2015). Chitosan boosts plants' defenses and can even increase resistance to plant pathogens (Sharma et al., 2019). Chitosan is derived from chitin, which is an antitoxic substance. Especially in low doses, chitosan can improve a plant's resistance to pathogens by strengthening its immune system (Ngo et al., 2015). Chitosan protects cells against plant pathogens through lipid ARTICLE INFO

The effect of interaction between salicylic acid and drought stress on growth and photosynthetic rate of Basella alba and B. rubra

“…Salicylic acid and its derivatives sprayed on the leaves increased drought tolerance in Basella experiencing dry stress. Research shows that the application of salicylic acid (Morovvat et al 2021) reported treatment of potatoes showed a significant effect on the water supply status of the plants; the effect of salicylic acid on irrigation treatment 60 and 80% showed an increase in potato yields under severe drought stress conditions. The best yield treatment was salicylic acid treatment with 100% irrigation.…”
