KH_2PO_4和赤霉素复合液对苦瓜种子发芽和根系生长的影响

Effect of KH_2PO_4 and GA_3 on Seed Germination and Root Growth of Balsam pear(Momordica charantia L.)

研究不同浓度的KH2PO4和赤霉素复合液对苦瓜种子发芽的影响。结果表明:0.05%KH2PO4+100mg/L赤霉素复合液对揭农槟城苦瓜的发芽率、发芽势和根系生长的促进效果最佳,对揭农大顶苦瓜和英香34的发芽率、发芽势和根系生长促进效果最佳复合液为0.1%KH2PO4+100mg/L赤霉素,不同品种间的发芽率和发芽势存在差异。

Effect of the different concentrations of mixture of KH2PO4 and GA3 on the seed germination and root growth of Balsam pear was studied and the results showed that the mixture of KH2 PO4 and GA3 can influenced seed germination percentage, germination energy and root growth of Balsam pear. The results indicated that the mixture of 0. 05% KH2PO4 ＋100 mg/L GA3 was the best for Jienongbincheng（Balsam pear variety） ,that the mixture of 0. 1G KH2PO4 ＋ 100 mg/L GA3 was the best for Jienongdading and Yingxiang34（Balsam pear variety）. This study also suggested that the difference of germination percentage and germination energy were existing among different varieties.
