盐胁迫对航天诱变向日葵生理生化指标的影响
Effects of Salt Stress on Physiological and Biological Indices of Sunflower Induced by Space Flight
摘要
Abstract
[Objective] To study the changes of physiological and biochemical indices of sunflower induced by space flight under salt stress.[Method] Taking sunflower induced by space flight as test materials,they were treated with different concentrations of NaCl (0,0.3％,0.6％,0.9％ and 1.2％).SOD activity,POD activity,MDA content,soluble protein content and proline content were determined.The effects of salt stress on physiological and biochemical indices of sunflower induced by space flight were analyzed.[Result] SOD activity increased with the increase of salt concentration.When salt concentration was 0.6％,SOD activity declined.POD activity increased with the increase of salt concentration.The contents of MDA,soluble protein and proline decreased with the rise of salt concentration.When salt concentration was 0.9％,they increased.[Conclusion] Sunflower induced by space flight can grow normally at salt concentration of 0.9％.These results can provide theoretical support for screening out new sunflower material against salt stress.关键词
