温度对不同品种甘草种子萌发的影响

目的]确定人工栽培甘草的适宜播种期并为甘草的规范化栽培提供科学指导。方法]利用恒温培养箱,研究在10、15、20、25、30、35、40℃下不同品种甘草种子的萌发率。结果]乌拉尔甘草、光果甘草、胀果甘草的种子在10℃下的发芽率分别为77%、43%、30%,在15℃下的发芽率分别为80%、72%、34%,在20℃下的发芽率分别为70%、68%、30%,在25℃下的发芽率分别为80%、74%、21%,在30℃下的发芽率分别为91%、81%、16%,在35℃下的发芽率分别为80%、75%、35%,在40℃下的发芽率分别为94%、55%、21%。结论]乌拉尔甘草、光果甘草、胀果甘草种子萌发的最适温度分别为25-30、15-40、35℃。

Effects of Temperature on the Germination of Seeds from Different Glycyrrhiza Varieties

Objective] The aim was to ascertain the suitable sowing date of artificial cultivated glycyrrhiza and supply scientific guidance for its standardized cultivation.Method] With the help of constant incubator,the germination rates of seeds from different glycyrrhiza varieties at 10,15,20,25,30,35 and 40 ℃ were researched.Result] The germination rates of Glycyrrhiza uralensis,Glycyrrhiza glabra and Glycyrrhiza inflata were 77%,43% and 30% resp.at 10 ℃,80%,72% and 34% resp.at 15 ℃,70%,68% and 30% resp.at 20 ℃,80%,74% and 21% resp.at 25 ℃,91%,81% and 16% resp.at 30 ℃,80%,75% and 35% resp.at 35 ℃ and 94%,55% and 21% resp.at 40 ℃.Conclusion] The optimum temperatures for the germination of seeds from G.uralensis,G.glabra and G.inflata were 25-30,15-40 and 35 ℃ resp.
