水分胁迫对兰花品种“霞光”抗氧化系统的影响
Effects of Water Stress on Antioxidant Enzymes System of Orchid Cultivar "Xiaguang"
摘要
Abstract
[Objective] To study the effects of water stress on the antioxidant enzymes system of orchid cultivar "Xiaguang".[Method] Taking orchid cultivar "Xiaguang" as test materials,the changes of MDA content,SOD,POD,CAT activities of orchid cultivar "Xiaguang" under water stress at the early blossom stage were studied.[Result] MDA content,SOD,POD,CAT activities of orchid cultivar "Xiaguang" showed an increasing trend along with prolonging of water stress time.In the treatment of watering once every 10 days,oxidative damage of membrane lipid produced.In the treatment of watering once every 20 days,MDA content,SOD,POD,CAT activities of orchid cultivar "Xiaguang" all reached the maximum.That indicated the plants regulated metabolism of the activities of the antioxidant enzymes in response to water stress.[Conclusion] The research results can provide guide for the production and cultivation of orchid cultivar "Xiaguang".关键词
