两种不同种源麻疯树种子发芽特征探讨

比较分析两种不同麻疯树种源种子发芽率、发芽势、发芽速度、发芽指数、发芽条件以及外观品质，结果表明：种源、种壳、种质、湿度、氧气以及种子前处理影响了种子发芽率、发芽势、发芽速度、发芽指数；破壳比未破壳的发芽效果好，种源A比种源B种子发芽率高，发芽期间应保持一定的湿度和通气条件，前期的消毒、浸种也是必需的环节。

Germination characteristics of two different provenances ofJatropha curcas L. in Huidong County

The seed germination rate,germinating energy, germination speed, germination index, germination condition and appearance quality of two different provenances of Jatropha curcas L. were studied. The results showed that seed germination rate, germinating energy, germination speed, germination index were affected by the provenance, seed coat, seed quality, humidity, oxygen and the seed pretreatment; in the process of seed treatment, shell breaking is better than without shell breaking; the germination rate of provenance A is better than the germination rate of provenance B; during seed germination, maintain proper humidity and aeration condition, previous disinfection and seed soaking are very important.
