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。

[Abstract]
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.
