以当归苗为材料，设计单因素试验，研究了赤霉素浸根对温室当归苗出苗及生长进程的影响。结果表明，赤霉素能有效打破温室当归苗的休眠，并显著促进其出苗进程，对其生长进程有一定影响。当用80 mg/L赤霉素浸根时，纯土苗和基质苗的出苗率分别达到58.79%和43.76%，当归产量分别达到4 267.65 kg/hm2和 4 116.60 kg/hm2。

With Angelica seedlings as materials， the effects of gibberellin root-soaking on the emergence and growth progress of Angelica seedlings were studied via single-factor test. The results indicated that gibberellin could break the dormancy of greenhouse-cultivated Angelica seedlings， promote its emergence significantly and have some influences on growth progress. When 80 mg/L gibberellin was used to soak root at transplanting time， the emergence rate of pure soil-cultivated seedling and matrix-cultivated seedling was 58.79% and 43.76%， respectively； the yield of Angelica was 4 267.65 kg/hm2 and 4 116.60 kg/hm2， respectively.
