Hg污染胁迫对葡萄果树生理特性的影响
Effects of Hydrargyrum Stress on Physiological Indexes of Grape Plants
摘要
Abstract
[Objective]The research aimed to study the effects of hydrargyrum stress on physiological indexes of grape plants. [Method]Grapes was planted in pot and different content of hydrargyrum was added to soil. The chang of cell membrane permeability, proline contents,MDA content and SOD,POD,CAT activities in grape leaf in different cultivation times were analyzed. [Result] With the inerease of Hg content in soil,relative electric conductivity,MDA content,proline content and SOD activity in leaves of grape increased. POD ativity increased first and then decreased. Hg obviously inhibited CAT activity. In different cultivation times, relative electric conductivity and MDA content decreased with the growth of grape trees. It showed in an order of flowering period < young fruit growth period < turn color period < mature period. Proline content and SOD activity showed in the opposite order, namely flowering period > young fruit growth period > turn color period > mature period. POD activity showed mature period < flowering period < young fruit growth period < turn color period, while CAT activity showed young fruit growth period > turn color period > flowering period > mature period. [ Conclusion ] Lower concentration of Hg can increase the endurances of grape plants in short term. But with the higher concentration and the extension of time, the effect will decrease,even the growth will be inhibited.关键词
