| 摘 要： | 目的]探讨黄连木种子发芽率和出苗率.方法]采用不同种子处理方法、不同浓度赤霉素溶液处理、不同覆土深度进行试验.结果]黄连木种子吸水性较好,浸种48 h吸水就达到31.4％,接近种子饱和吸水量；经100、200 mg/L赤霉素溶液处理12 h,种子发芽率分别为21.6％和28.6％,高于对照且差异显著；去除外种皮后,再用草碳土对种子进行揉搓可明显提高种子的发芽率,其种子发芽率可达45.1％；加盖地膜和覆土深度1 cm能显著提高种子的出苗率.结论]该试验可显著提高种子的发芽率和出苗率.

| Abstract: | Objective] Explore pistacia seeds on germination percentage and rate of emergence.Method]Different seed treatment methods,different concentration gibberellin solution treatments,different overlying soil depth were tested.Result]The seeds have good water absorbency,such as the percentage of water-absorption after soaking seeds 48 hours was 31.4%,which was close to the seed saturated water absorbing capacity.Germination rate of the seeds were 21.6% and 28.6% respectively by after 100 mg/L and 200 mg/L gibberellin solution treatment for 12 h,this result were higher than that in the control group(P<0.05).Germination rate of the seed can be obviously improved by removing testa and then kneading seed.The maximum germination rate increased 43.8%.Emergence rate of pistacia seeds can be obviously improved by a method that cover plastic film and overburden depth 1 cm.Conclusion] The test can significantly increase the seed germination rate and seeding emergence rate. |
