Abstract:: Taking Polygala fallax Hemsl.seeds as materials，the effect of temperature(20℃,25℃,25/30℃,30℃) and light，germination substrate，maturity of seeds,drying time,gibberellin soaking concentration on the germination rate of it were studied.The results showed that the trend of the germination rate increased was 25℃＞20℃＞20/30℃＞30℃.The light and appurtenances had limited effect on the germination of the seed.The germination of the seeds reached the maximal when the seed was maturity.The germination of the seeds increased after 100 mg/L gibberellin treated 6 hours and decreased when the soaking time was from 6 to 24 hours.The optimal condition for the germination of Polygala fallax Hemsl.seeds was as follow：germination substrate loess，temperature 25℃ under light.The seed should be harvested and saved in time.
