桃儿七种子发芽促进剂的研究

目的]选择适宜桃儿七种子萌发的发芽促进剂,以提高桃儿七种子萌发率。方法]用不同浓度的碳酸氢钠、碳酸钠、细胞激动素、赤霉素、萘乙酸、6-苄基-嘌呤和2,4-D等7种药剂处理桃儿七种子,通过测定种子发芽率、发芽势、发芽指数和发芽速度等活力指标研究药剂对桃儿七种子萌发的促进作用。结果]不同药剂对桃儿七种子的促进作用不同。经方差分析和F值检验,确定适合桃儿七种子发芽的促进剂碳酸氢钠和碳酸钠。结论]该研究为人工种植桃儿七提供了科学依据。

Study of Germination Promoter of Sinopodohyllum hexandrum Seeds

Objective] The research aimed to screen out the optimum germination promoter to improve germination rate of Sinopodohyllum hexandrum seeds.Method]Sinopodohyllum hexandrum seeds were treated with different concentration NaHCO3,Na2CO3,KT,GA3,NAA,6-BA and 2,4-D.The effects of different chemicals on Sinopodohyllum hexandrum seeds were measured,and seed germination rate,germinability,germination index and germination speed were determined.Result] Different chemicals had different impacts on Sinopodohyllum hexandrum seeds.Among seven chemicals,NaHCO3 and Na2CO3 were the optimum germinate promoters,which were confirmed by SSR.Conclusion] The study provided the basis for the cultivation of Sinopodohyllum hexandrum.
