摘要
Abstract
The rice seed was soaked in Ce(NO3)3 solution with concentrations from 2.5～30mg/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.关键词
