Study the effect of salt stress on physio-biochemical traits of wheat

Abstract

A pot experiment was conducted during rabi season, 2018 in the cage house at Department of Plant Physiology, S.K.N. College of Agriculture, Jobner, Rajasthan to study the Investigate the effect of salt stress on physio-biochemical traits of wheat. Wheat cultivars namely Raj-4037 (salinity susceptible) and Raj-3077 (Salinity tolerant) were grown in ceramic pots under salinity conditions (0, 4 and 8 dSm-1). Control plants were provided normal water. Different physio-biochemical observations were recorded at 55 and 75 days after sowing in pot conditions Result revealed a significant decrease were recorded in chlorophyll content, protein content, relative water content, cell membrane stability whereas, proline content and reducing sugar increased with salt stress up to EC 8 dSm-1 in both the cultivars at 55 and 75 DAS. Reduction in physio-biochemical traits contributing parameters on account of salt stress was more in cultivar Raj-4037 whereas, proline content and reducing sugar increased. On the basis of research findings genotype Raj-3077 observed most salt tolerant and the tolerance was mediated by physio-biochemical traits characteristics.
