摘要
以单子叶植物番红花为材料,研究了钙离子对其活性氧代谢的影响.随钙水平降低,除SOD外,膜保护酶(POD,CAT)和抗氧化剂(AsA)均一直下降,导致O-2.产生速率、膜脂过氧化作用、质膜透性增加.说明钙离子对番红花活性氧代谢有明显的影响.
Monocotyledon Crocus sativus L.treated with different calcium levels.Study on the effect of calcium on active oxygen metabolism in Crocus sativus leaves.The results were as follows:with the [Ca 2+ ] decreasing,the rate of O\+- 2· production and the content of MDA as well as the membrane permeability increased.Except the activity of SOD,the content of AsA and the activity of POD and CAT decreased rapidly.Thats to say, calcium affects active oxygen metabolism in Crocus sativus obviously.
