| 摘 要： | 用2.5～30 mg/L的Ce(NO3)3处理水稻种子能加快萌发， 明显提高种子活力， 促进植株根系生长， 增加叶绿素含量。 这是由于在用Ce(NO3)3处理期间加快了种子的吸水速率， 增加了膜的通透性， 增强了呼吸作用， 增加了种子萌发期间IAA、 GAs和CTK等植物激素的含量， 而ABA含量变化不大。 其中用10 mg/L Ce(NO3)3处理效果最佳，

| Abstract: | The rice seed was soaked in Ce(NO3)3 solution with concentrations from 2. 5 - 30 mg/ L for 48 h. Results showed that the germination of seed and the root growth was promoted and chlorophyll contents in the seedling increased. It probably was the soaked seeds increased absorption water rate, membrane permeability and respiration rate of seed, enhanced contents of IAA, GAs and CTK(but ABA contents were relatively stable during germination). The soaking treatment with 10 mg/L Ce(NO3)3 was recommendable, and that with 50-70 mg/L Ce(NO3)3 could inhibit the germination. |
