川党参种子发芽检验规程的研究

Study on seed germination testing standardization of Codonopsis tangshen

目的:探讨温度、光照、发芽床等因素对川党参种子发芽的影响。方法:常规发芽试验方法进行试验。结果与结论:川党参种子发芽最适温度为25℃,需光照,发芽床选纸上或纸间均可,发芽初次计数时间为置床后第10天,末次计数时间为置床后第18天。以赤霉素处理可显著提高川党参种子的发芽率。

Objective： To study the influence of different factors （temperature, light and germinating beds） on seed germination of Codonopsis tangshen. Method ：The general germination method was applied. Result and conclusion ：The optimum seed germination conditions of C. tangshen were as follows： temperature 25℃, light, germ/nating-beds top of paper （TP） or between of paper （BP）. The first seedling - counting time was the 10th day after beginning the test;the final time was the 18th day. The test also showed that gibberellin notably increased the seed germination rate of C. tangshen.
