Abstract:
Among all the stresses crop plants experience during their lifecycle, drought has a significant importance particularly in areas where precipitation is scanty and rainfed irrigation is followed. Lentil is an important pulse in India and it is sensitive towards water deficit conditions. Water deficit triggers an array of biochemical responses in Lentil, ROS production being the major one. In the present study, we evaluated four lentil genotypes for their ROS production level under water deficit. H₂O₂, HO^-, lipid peroxidation, SOD, Catalase and Guaiacol peroxidise levels were determined. L₃ exhibited highest (48.17%) increase in H₂O₂ and L₄ showed highest OH- levels. Lipid peroxidation was found to be lowest in L₂ whereas minimum SOD increase was observed in L₃. The genotype L₃ showed maximum catalase activity. However, maximum increase in Guaiacol peroxidase activity was observed in L₃.
