Abstract:

Effect of sodium arsenate (Na2HAsO4.7H2O) on the growth of mungbean seedlings was investigated and it was found to have drastic effects on the germination and growth of mungbean (Vigna radiata (L.) Wilczek cv. B-105) seedlings. Percentage of seed germination was found to decrease  significantly with increasing concentrations (5μM, 10μM and 20μM)  of  arsenate. Reduction in seedling length - shoot length, root length, area of primary leaves, fresh weight and dry weight was also observed. Similar decreasing trend was also recorded in case of amylolytic enzyme activity i.e. amylase activity of the seedlings. However, reduction in seedling growth inhibition was achieved by pretreating the seeds with macronutrients (KH2PO4, NaH2PO4.2H2O, K2SO4, CaCl2.2H2O, MgSO4.7H2O at 10mM concentration), micronutrients (ZnSO4, CuSO4, Na2MoO4.2H2O, MnCl2.4H2O, CoCl2.6H2O, FeSO4.7H2O at 1mM concentration) and organic acids (pyruvate, citrate, malate, fumarate, succinate at 10mM concentration); best results were shown by KH2PO4, NaH2PO4, CoCl2 and Pyruvate from above mentioned three respective groups. These vital compounds used  in  the  present   study helped in the  mitigation of arsenate induced growth inhibition to different degrees. Growth enhancement of seedlings caused by these two phosphate salts with different cations indicates that anion phosphate and not cations (Na and K) is responsible for the beneficial effect.
