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

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.
