不同处理对柴胡种子萌发的影响

Effects of Different Treatments on Germination Rate of Bupleurum chinense Seeds

对柴胡种子进行自来水浸种、沙藏处理及6-BA、赤霉素、H_2O_2和KMnO_4药剂处理试验,以研究不同处理对柴胡种子发芽率的影响。结果表明,柴胡种子经自来水浸泡,随浸泡时间的延长,发芽率升高。H_2O_2、6-BA、沙藏对柴胡种子发芽有抑制作用,适宜浓度的KMnO_4和赤霉素对柴胡种子发芽有促进作用。加热100℃60mg/L赤霉素浸泡24 h的柴胡种子发芽率高于其他处理,发芽率达32.00%;用自来水浸泡48 h次之,发芽率为30.00%;用6-BA处理过的柴胡种子未见发芽。

The effects of different treatments on the germination rate of Bupleurum chinense were studied,under the treatments of water immersion,sand burying,6-BA,gibberellin, H2O2 and KMnO4. The results showed that when the seeds of Bupleurum chinensis were soaked with tap water,the germination rate was increased with the lengthening of the soaking time. H2O2,6-BA and sand burying all had inhibitory functions on the germination of Bupleurum chinese seeds. The suitable concentrations of KMn O4 and gibberellin all had promotion functions on the germination of Bupleurum chinese seeds,in which the germination rate of Bupleurum chinense seeds treated with 60 mg/L gibberellin for 24 hours at 100 ℃ was higher than that of other treatments, the germination rate reached 32%;the second effective treatment is soaking in tap water for 48 hours,its germination rate reached 30.00%; The Bupleurum chinese seeds treated with 6-BA showed no germination.
