| 摘 要： | 以周麦18、百农AK 58两种小麦的新、老种子为试验材料,进行小麦发芽试验、老化处理和抗冻处理来了解两个品种新、老种子的活力情况；再通过测吸光值法对两品种新老种子的过氧化物酶(POD)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)的活性进行测定.结果表明,同一品种小麦的新种子在3种条件下的发芽率明显大于其老种子；同一品种小麦的新种子的过氧化物酶、超氧化物歧化酶、过氧化氢酶的活性明显大于其老种子,电泳图谱结果也与之一致.种子活力与种子内过氧化物酶、超氧化物歧化酶、过氧化氢酶的活性成正相关.另外,从周麦18,百农K 58的相关数据和酶谱的对比,得知百农AK 58的种子活性及其稳定性明显优于周18.

| Abstract: | The paper selected old and new wheat seeds of Zhou 18 and Bainong AK 58 as the experimental material.First,old and new seed vigor were measured through the non-special processing germination experiment,aging treatment germination experiment and anti-freeze processing germination experiment of wheat.Then,with the method of measuring absorb light,the activities of peroxidase(POD),superoxide dismutase(SOD) and catalase(CAT) of old and new seeds were measured.Results demonstrated that the rate of germination of... |
