Abstract/Description: | The groundnut, mostly grown as rainfed in the arid and semi-arid regions is highly vulnerable to drought stresses of varying duration and intensity due to uncertain rainfall pattern (SINGH et al., 2013). Depending on the time of occurrence, drought has been characterized as early season, mid-season, and end-of-the-season drought. Mid- and end-of-the-season droughts are critical as they affect the pod yield and quality (JANILA et al., 2013). Water deficit stress during pod-development phase is detrimental to several physiological and biochemical processes (NAUTIYAL et al., 1991).Water stress conditions disturb photosynthetic activity of plants and thereby affects further vegetative growth and the mobilization of assimilates towards storage or sink tissues. Sugars in plants, derived from photosynthesis, act as substrates for energy metabolism and the biosynthesis of complex carbohydrates, providing sink tissues with the necessary resources for growth and development. Responses to a specific stress can vary with the genotype, but some general reactions occur in all. Under sugar depleted condition, substantial physiological and bio-chemical changes occur to sustain respiration and other metabolic processes (JOURNET et al., 1986) Sucrose and glucose either act as the substrates for cellular respiration or as the osmolytes to maintain cellular osmotic potential (GUPTA et al., 2005). |
