Water deficit is one of the major abiotic stresses which adversely affect the crop growth and yield. Moisture stress induce the metabolic functions, such as reduced synthesis of photosynthetic pigments, accumulation of osmoprotectants like proline, decline in the Chlorophyll stability and alterations in physiological parameters. The Field experiment was conducted at Agricultural College and Research Institute, Madurai during summer season 2016 with the variety of SVPR - 4. To study the effect of moisture stress regimes on physiological parameters of Relative Leaf Water Content (RLWC), Chlorophyll Stability Index (CSI), Proline accumulation in leaf and Seed cotton yield. Experiment was laid out in split plot design with three replications. |
