Quantification of biochemical attributes of pigeonpea (Cajanus cajan L.) under waterlogged condition

Vinay Pratap Singh and JP Srivastava
The present study was conducted to assess the genotypic variability for waterlogging tolerance and related biochemical attributes which is vital in withstanding waterlogging stress in pigeonpea crop at the early seedling stages. Quantification of the amount of proline, sugar, starch and enzymes related to antioxidant defence mechanism in three pigeon pea genotypes under waterlogging condition was performed to satisfy objective of this research. Proline content increased significantly in leaves, and the increment was more in waterlogging resistant genotype. Soluble sugar content in leaves increased and it was attributed to increased hydrolysis of stored polysaccharides as the starch content concomitantly declined. Starch content in leaves of waterlogged plants undergoes significant reduction. Activities of enzymes super oxide dismutase and peroxidase increased significantly. Increments in super oxide dismutase and peroxidase were more in waterlogged plants of susceptible genotype MAL-18. Hydrogen peroxide content was almost unchanged in ICPL-84023, but increased in susceptible genotype MAL-18. Higher osmolytes accumulation, lesser H2O2 accumulation and antioxidant enzymes activities leads to lesser yield in tolerant genotype in comparison to susceptible genotype, leads to least yield decline in tolerant genotypes compared to susceptible.
