Abstract
Study was conducted on the effects of the two chloride channel blockers Zn2+ and NA(niflumic acid)on ion contents,membrane permeability and osmotic potential in the seedling leaves of two Glycine soja populations(BB52,the salt-tolerant;N23227,the salt-sensitive)and G.max cultivar(Lee68,the salt-tolerant)under salt stress.The results showed that,the K+ contents in seedlings,the contents of NO3-,chlorophyll and the osmotic potential in leaves of the 3 soybeans significantly decreased under 150 mmol·L-1 NaCl after 6 d compared to the control.However,the contents of Cl-,malondialdehyde(MDA)and the relative electrolytic leakage increased.Under NaCl stress plus additional 20 μmol·L-1 Zn2+,the contents of K+,NO3-,chlorophyll and the osmotic potential obviously increased,the contents of Cl-,MDA and relative electrolytic leakage obviously decreased compared to the NaCl treatments.The NaCl stress plus additional 20 μmol·L-1 NA showed the reverse.In regard to the experimental soybean materials,more obvious effects showed on seedlings of G.max.It indicates that,Zn2+ may alleviate the chloride/salt injury on soybean seedlings under NaCl stress.
