Abstract: The effects of different NaCl solutions on the morphological and physiological indexes of Zhuliu plants under sand-cultured were studied.The results showed that,with the increase of NaCl concentration,the height and the stem diameter decreased continuously,and significant difference was observed compared with the control..The leaves of Zhuliu appeared different degrees of dry rot yellowing,and growth vigor recession.And the water content,electrical conductance,MDA content increased gradually.The content of chorophy,proline,soluble sucrose were increasing at first and then declining later,showing regularity changes.The salt tolerant threshold of Zhuliu was deduced as 0.5% and survival threshold was 0.8% by observing visual form and analyzing physiological index.The research provided the scientific basis for exploitation and utilization of Zhuliu in saline-alkali land.

Key words: Zhuliu, NaCl stress, Morphological index, Physiological index
