摘要
盐适应烟草愈伤组织与不适应愈伤组织K+．Na+含量一致，Na+吸收速率下降；与无NaCl培养基上生长的愈伤组织相比，K+含量下降，Na+含量大幅度上升，Na+吸收速率下降．结果表明，Na+缓慢吸收可减轻Na+积累的毒害．
Compared salt-adapted tobacco cullus with salt-unadpted cullus, the content of K+. Na+ was unanimous, the absorbing Na+ rate descended. As comparing with cullus which grown on culture medium wethaut adding NaCl, the content of K+ decreased, the content of Na+ increased greatly and the absorbing Na+ rate decreased. All these results suggested that slowly absorbed Na+ can lessen toxicity of Na+ accumulation.
