刚毛柽柳体内Na+积累对盐分与水分胁迫的响应研究
Effects of Salt and Drought Stress on Na+ Accumulation in Tamarix hispida
摘要
Abstract
[ Objective] The aim was to study the effects of salt and drought stress on Na+ accumulation in Tamarix hispida. [ Method] Tamarix hispida was treated by different levels of salt and drought stress, and then Na + accumulation in Tamarix hispida was determined by ICP - AES.[ Result] Na+ accumulation in Tamarix hispida was in order of leaf ＞ root ＞ stem, among them leaf was the main part of Na+ accumulation,while the stem was only a transport channel for Na + , so there was no cumulative process. Na+ content of Tamarix hispida increased with the increase of NaC1 concentration, and also increased with the increase of stree time. Na+ content of Tamarix hispida decreased with the increase of irrigation, reduced the osmotic potential of root, and also made the root to maintain mositure around the high NaCl concentration. Na+ contents in root and stem of Tamarix hispida increased gradually with the increase of stress time, while Na + content in leaf increased firstly and then decreased. [ Conclusion] The research provides reference for the restoration and reconstruction of damaged ecosystem in the lower reaches of Tarim River.关键词
