Water, Salt and Freezing Stresses: Effect on Relative Water Content, Viability and Banding Patterns of some Isozymes In Brassica Juncea (L) Czern. Callus
Abstract
A comparative study on the effect of water, salt and freezing stresses on relative water content (RWC), viability and banding patterns of some isozymes (esterase, peroxidase and acid phsophatase) was made in Brassica juncea callus. RWC in different stress affected tissues was more or less similar though, effect on viability was different Salt stress, in particular, was most injurious to the tissue. Different kind of stresses also affected the banding patterns of the isozymes. In isoenzymic profile of esterase, intensity of one specific band got diminished while another showed a gradual decline under all stress conditions.
