复盐胁迫对结缕草(Zoysia Willd.)生理和生长的影响研究
Mixed Salt Stress on Effects of Physiology and Growth of Zoysia Willd.
摘要
Abstract
It is important to study the effects of salt stress on plant physiology and growth to reveal the mechanisms of plant salt tolerance and cultivation management. This paper took Zoysia matrella and Zoysia sinica as the test materials to study the CAT and SOD activity, the content of total soluble sugar and proline, relative electrical conductivity, leaf water content, relative growth rate and turfgrass quality under 0.5% mixed salt stress. The results showed as the following: CAT activity, the content of proline and relative electrical conductivity of the two Zoysiagrasses increased gradually; the relative growth rate, turfgrass quality, SOD activity and content of TSC of the two Zoysiagrasses increased firstly and then decreased; leaf water content decreased gradually. Z. matrella had larger SOD and CAT activity, accumulated more osmotic adjustment substances, maintained good cell membrane integrity and water holding capacity, and showed larger relative growth rate and the turfgrass quality during salt stress compared with Z. sinica, this may be the reasons that Z. matrella was more resistant to salt stress.关键词
