Abstract

Abstract: The physiological responses of the leaves of bo chinensis under NaCl⁺ stress andmitigating action of Ca to NaCl stass were studied.The asults show tha L.chinensis adopted to salin-ization drinly by toleance to Na⁺ as increase of Na⁺ as increase of proline for permeability regulation.Under salt stress condition, the external souroe of Ca₂⁺ could increase of chlorophyle content of the leavesand incna of photosyntheisis, which mitigated Na⁺ stress.

Key words: NaCl stress, Permeability, Ca₂⁺ treatmeat

摘要： 在不同浓度NaCl营养液模拟的土壤盐化胁迫条件下,研究盐分对羊草的生理和代谢反应,结果表明,羊草对Na⁺胁迫的适应方式以耐胁性为主,通过吸收无机离子和积累脯氨酸进行渗透调节。在Na⁺胁迫基础上进行钙处理,结果表明外源钙对Na⁺危害有-定的缓解效应。可为今后治理盐碱化草场提供新的途径。
