摘要
以麻花艽种子为试材,研究其在不同温度下的种子活力,测定其发芽率、发芽势、发芽指数,探讨引种驯化最易成功的最佳发芽温度,以期为麻花艽的人工栽培提供理论指导。结果表明:麻花艽种子浸泡20h后即达到吸水饱和期;在20℃时其发芽率、发芽势和发芽指数最大。因此,20℃为发芽最适温度。
Taking Gentiana strarninea Maxim. seed as test material, the germination rate, germination energy and germination index were studied under the different temperature in order to find the best germination temperature of the greatest success for introduction and domestication. Arel to provide a theoretical guidance on the artificial cultivation of Gentiana strarninea Maxim. The results showed that seeds of Gentiana strarninea Maxim. reached water saturation after they were soaked 20 hours; at 20℃, the germination rate, germination energy and germination index were all the most. Therefore,the optimum germination temperature was 20℃ .
