盐分胁迫对观光木幼苗生长及生理特性的影响
Effects of Salt Stress on Growth and Physiological Characteristics of Tsoongiodendron odorum Seedlings
摘要
Abstract
Effects of salt (NaCl) stress of different concentrations on growth and physiological responses of one year old Tsoongiodendron odorum seedlings were studied in pots containing soil. The results showed that the effects of salt stress on height increment, relative electric conductivity, SOD activity, proline and chlorophyll content of T. odorum seedlings were extremely significant. With the increase of salt concentration, height increment and chlorophyll content decreased,relative electric conductivity increased; SOD activity increased and then decreased, but that was higher than control, and reached the maximum on 0. 2% concentration;proline content decreased and then increased slightly with the increase of salt concentration, but that was lower than control. Analysis of correlation showed that correlation coefficient among salt concentration and height increment, relative electric conductivity, and chlorophyll content all reached over 0. 973,indicating the close relationship between them. However, the relevance among salt concentration and SOD activity, and proline content was not significant.关键词
