Alterations in Proline Metabolism in Groundnut (Arachis Hypogaea L.) Under Soil Water Deficits

Water stress induced proline accumulation and antioxidative enzymes in groundnut (Arachis hypogaea L.)

“…It is also associated with lower levels of RWC. Our results of proline accumulation are in agreement with the results of reported in groundnut (Madhusudhan and Sudhakar, 2014), in horse gram (Bhardwaj and Yadav, 2012) and in chickpea (Kumar et al 2006;Mafakheri et al 2011).…”

“…This might be due to reduction in water availability, stomata opening and closing is more affected. Similar results have been repor ted in groundnut (Madhusudhan and Sudhakar, 2014), in horsegram (Bhardwaj and Yadav, 2012) and in pigeonpea (Kumar et al, 2011). The results obtained in the present study are in agreement with these reports.…”

“…It has been reported that the loss of chlorophyll under water stress is due to inactivation of photosynthesis (Kumar et al, 2011), furthermore, stress induced reduction is ascribed to loss of chloroplast membrane integrity due to lipid peroxidation (Manivannan et al, 2007). The decrease of photosynthetic pigment under water limitation has been considered a typical symptom of oxidative stress and may be result of pigment photo-oxidation and chlorophyll degradation and prevent its biosynthesis have been reported in peanut (Farooq et al,2009;Sharada and Naik 2011;Kumar et al, 2011;Madhusudhan and Sudhakar, 2014) A marginal but significant increase in soluble protein was observed in all water stressed seedlings of groundnut except RHRG-6083. The soluble protein content in the leaves of control plants range from 13.75 -18.94 mg/ g fr.…”
