ABSTRACT

Environmental stresses limit agricultural productivity worldwide. Stresses have an effect on crop species. Among the many environmental stresses, salinity is inflicting immense modification in the plant growth and physiology and agricultural productivity. Pigeonpea (Cajanus cajan) is a vital grain legume of the Indian landmass, South-East Asia and geographic region. Over 85% of the globe pigeonpea is produced and consumed in India wherever it's a key crop for food and nutritionary security of the individuals. In the present study, pot culture experiment were conducted to estimate the impact on NaCl stressed pigeon pea (Cajanus cajan L.). The seeds of 10 pigeon pea genotypes were seeded in plastic pots. After 20 days of sowing, the plants were treated with 50mM concentration of sodium chloride. The plants samples (leaf) were collected for estimating pigment, Physiological and biochemical contents. The sodium chloride treatments have an effect on the chlorophyll-a, b, total pigment, protein content and different parameters. Similarly, the amino acid and proline content were additionally affected with increasing concentration of NaCl to a bigger extent when put next to manage in all the treatments. As per the result obtained in our study, AH-06-7, MANAK, ICP 5028, H-2001-25, SGBS-6 and ICP 14085 were observed as salinity tolerant varieties and remaining four i.e., PAU881, A. H-06-9, MAL 15 and ICPL 88039 were identified as sensitive cultivars based on the physiological, biochemical and antioxidants enzymes response under salinity stress condition.
