Abstract:
The effects of salt stress on root growth,root border cells(RBCs)development,Na+ and K+ content and physiological characteristic in black soybean\[Glycine max (L.)Merrill\]were investigated,with RBCs adhered to root tips using a static cultivation method,or with RBCs removed from root tips using a shaking cultivation method.Salt stress treated with 100 and 200 mmol·L-1NaCl inhibited RBCs development and increased relative electric conductivity and MDA content in roots.Physical removal of RBCs from root tips for 36 h resulted in a more severe inhibition of root elongation and a higher Na+ accumulation in the root tips,the relative electric conductivity and MDA content in roots were also significantly increased when RBCs were removed.The results revealed that RBCs adhered to the root tips tended to regulate the uptake of Na+ and K+,and maintain cell membrane integrity,thereby increased salt tolerance in black soybean seedlings.
