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(P<0.01),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.
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 （±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.
