摘要
6-苄基腺嘌呤(6-BA)和胆固醇配合处理水稻种子,可促进水稻幼苗的生长,提高冷害水稻幼苗的膜保护酶超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)的活性,降低膜脂过氧化产物丙二醛(MDA)的含量,提高可溶性糖、可溶性蛋白质、脯氨酸及ATP含量,增强水稻幼苗的抗冷性。6-BA和胆固醇配合施用对促进水稻幼苗生长和增强抗冷性的效果优于胆固醇单独处理,但比6-BA单独施用效果稍差。
The seeds of paddy rice (Oryza sativa) variety II You 6078 were treated with cholesterol and 6-BA, alone or in combination. The results showed that cholesterol and 6-BA enhanced the activities of SOD, POD and CAT, raised the contents of soluble sugars, free praline, soluble protein and ATP, and decreased MDA contents in rice seedlings, thus improving their cold resistance. The effects of cholesterol in combination with 6-BA were superior to those of cholesterol applied alone and inferior to those of 6-BA applied alone.
