摘要
使用不同浓度的赤霉素GA3浸泡猪屎豆和黄葵种子,研究对种子萌发的影响。结果表明:200 mg/L的GA3处理对猪屎豆的催芽效果最好,而100 mg/L的GA3处理对黄葵的催芽效果最好;GA3浸种催芽对种子的发芽势和发芽率有一定的促进作用,种子发芽率、发芽势有提高,但效果不显著。GA3的浓度过低或者过高,对种子发芽率的影响不明显。
Gibberellin was used to study the effect of the different concentration soaking on the seed germination of Crotalaria pallida and Abelmoschus moschatus. The results indicated that both the seed germination rate and germination potential increased,The different concentrations soaking by Gibberellin had different effect on the seed germination of Crotalaria pallida and Abelmoschus moschatus, the best density was 200mg/L to Crotalaria pallida and the best density was 100mg/L to Abelmoschus moschatus.
