RESPONSE OF PIGEONPEA (Cajanus cajan L. Millsp.) GENOTYPES UNDER WATER LOGGING STRESS
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 25
Abstract
Water logging stress was imposed on two pigeonpea genotypes viz., ICPL-84023 and DA-11. Thirty days old pot grown plants were subjected to water logging continuously for 4 and 6 days in water filled containers and water was maintained 4-5 cm above the surface of soil. Significant genotypic differences were observed with respect to biochemical changes in leaves and roots. Chlorophyll content was found more in ICPL-84023 genotype as compared to DA-11 in control condition. After imposition of water logging stress ICPL-184023 genotype performed better as compared to DA-11 genotype. ICPL-84023 genotype showed less chlorophyll reduction, increased activity of antioxidant enzymes peroxidase, catalase, superoxide dismutase and ascorbate peroxidase, and less H2O2, MDA content as well as less cell membrane leakage. In this study DA-11 was observed as susceptible and ICPL-184023 as tolerant genotype under water logging stress.
