Effect of electrolyte leakage activity on Mungbean leaf under induced salinity and zinc levels

Mungbean (Vigna radiata L.) is an excellent source of high quality proteins. In sprouted mungbean, high level of ascorbic acid, riboflavin and thiamine is found. But the production of mungbean is threatened by salinity. In the present study, observations were made for two consecutive years regarding the electrolyte leakage activity level in mungbean leaves under induced salinity conditions. Ten different treatments comprising of various levels of NaCl and Zn separately and in combinations i.e. 40mM NaCl, 80mM NaCl, 120mM NaCl, 40mM NaCl+2×10-5M Zn, 80mM NaCl+3×10-5M, 120mM NaCl+ 4×10-5M, 2×10-5M Zn, 3×10-5M Zn and 4×10-5M Zn were applied to salt stressed mungbean along with control. The treatments were replicated thrice and the statistical analysis was done using CRD. Under study of effects of various salinity levels electrolyte leakage activity (%) was increased under salt stressed mung bean (Vigna radiata L.) pre-treated foliar application of Zn reduced the ion accumulation. The treatment 120mM NaCl+ 4×10-5M Zn gave the best results with minimum electrolyte leakage as compared to control.
