Agriculture is directly linked to human life, providing food for survival and health. It threatened by a number of challenges, such as climate change, resource depletion, abiotic stresses, including heavy metals (HMs), salinity, drought, etc. Various strategies have been employed palliate the phytotoxic effects these stressors from soil–plant system. Nanotechnological approaches emerged promising tool increasing crop productivity promoting sustainable agriculture. Interestingly, seed nano-priming approach has shown potential against all above-mentioned stress factors improved productivity. The application nanoparticles (NPs) via priming an innovative cost-effective that improves germination subsequent plant growth activating physiological processes tolerance various stresses. with NPs induces electron exchange increases surface reaction capabilities related cell tissue components.

Melatonin as a Foliar Application and Adaptation in Lentil (Lens culinaris Medik.) Crops under Drought Stress

Sustainability, Journal Year: 2022, Volume and Issue: 14(24), P. 16345 - 16345

Published: Dec. 7, 2022

Here, we grow two different varieties of lentil (lentil-2009 and lentil-93) under drought levels with applications melatonin. Increasing the soil water deficit significantly decreased numerous morphological biochemical characteristics, including shoot length, total chlorophyll content, transpiration rate, in both lentil. Contrastingly, stress increased concentrations malondialdehyde (MDA) hydrogen peroxide (H2O2), electrolyte leakage, an indicator oxidative damage to membrane-bound organelles. The activities enzymatic antioxidants osmolytes were initially up a level 80% field capacity (WFC) but gradually higher (60% WFC) soil. At same time, results also showed that lentil-2009 is more tolerant than lentil-93. negative impact can be overcome by application Melatonin plant growth biomass, photosynthetic pigments, gas exchange enhanced various non-enzymatic proline content decreasing stress. We conclude foliar melatonin offers new possibilities for promoting tolerance.
