摘　　要：通过响应面法优选乌腺金丝桃种子的最佳萌发工艺。以发芽率为评价指标,研究温度、赤霉素浓度及浸泡时间、pH对试验的影响,采用中心组合原理设计试验,通过响应面法进一步分析,最终以可行性和经济学确定乌腺金丝桃最佳萌发工艺。结果表明,乌腺金丝桃种子最佳萌发条件为:温度22℃,2.6g/L的赤霉素浸泡35h,在pH值为6的培养皿中进行萌发。Optimizing Germination of Hypericum attenuatum by using response surface method. Using Germination rate as the evaluationg index, study on effect of temperature, GA, soaking time, pH on the test. By using Central composite design experiment, further analysis by response surface method. And ultimately to determine feasibility and Economics best germination of Hypericum process. Results show：The best germination technology of Hypericumattenuatum seeds is at 22 ℃ ,2.6g/L GA pH6 and soaking for 24hours.
