| 摘 要： | 以花毛茛杂交种子为材料,研究在(–1±0.2)、(2±0.2)、(5±0.2)℃条件下分别冷贮15、30、45d对种子萌发的影响.结果表明,低温预处理对花毛茛种子萌发有显著的促进作用,与对照相比,T1t2预处理的种子萌发效果最显著(P0.01),萌芽势提高了37.70%,萌芽率提高了21.60%,种子活力指数增强了0.36.

| Abstract: | Ranunculus asisticus seeds were treated with (-1±0.2),(2±0.2),(5±0.2) ℃ for 15,30,45 d,its effects on seeds germination were studied.Rresults showed that: the pre-chilling could significantly increase the seed germination.Compared to CK,the best treatment was (-1±0.2) ℃ for 30 d(P< 0.01),in which the seeds increased by 37.70% in its germination energy and by 21.60% at its germination rate and by 0.36 in its vigor index. |

| Keywords: | pre-chilling Ranunculus asisticus seeds germination |
