摘要: 用EMS及60Co处理海甘蓝种子,对其萌发种子细胞内呼吸代谢有明显的影响。低浓度的EMS或低剂量的60Co刺激呼吸,可提高抗坏血酸氧化酶和过氧化物酶的活性,促进种子的萌发和幼苗的生长。较高剂量的EMS和60Co抑制呼吸,与之有关的抗坏血酸氧化酶和过氧化物酶的活性、种子发芽势和发芽率、幼苗生长高度和根系活力等随之下降。用不同剂量的EMS和60Co处理海甘蓝种子,对M1代的产量和抗病性等有一定的影响。

Abstract: Physiological process of germinating Crambe seeds was significantly influenced by the treatment of different concentration and dose of EMS 60Co. Low-level of them could stimulate the respiration and raise the activities of ascorbic acid oxidase and peroxidase which associated with higher rate of seed germination and growth of seedling. High-level had inhibiting effects on respiration and the activities of related enzymes, the germinating potential of seed and the rate of germination and the vigor of root system decreased. The yield per plant and the resistance to disease of M1 generation of Crmbe abyssinica were also influenced by the treatment of different concentration and dose of EMS 60Co.
