摘　　要：用不同浓度的 H2 O2 、KH2 PO4、肌醇 ,在 15℃条件下浸种瓜尔豆种子 2 4h,研究它们对种子活力的影响。结果表明 :0 .6 %、0 .9%、1.5 %的 H2 O2 能显著或极显著提高种子的发芽率、发芽势、发芽指数 ,使幼芽生长整齐健壮 ,同时降低种子内可溶性蛋白质的外渗和降低种子电解质渗漏率 ,尤以 0 .9%的 H2 O2 效果最佳。 15× 10 - 6的肌醇和 0 .5 %的 KH2 PO4也能显著提高种子的发芽率 ,但对其它指标的影响不大。In this paper, we studied effects of different concentration of H 2O 2(0.6%,0.9%,1.5%),KH 2PO 4(0.1%,0.5%,1%) and inose (5×10 -6,10×10 -6,15×10 -6) presoaking at 15℃ temperature for 24 hours on bourgeon and vigor of Cyamopsis tetragonoloba(L) seeds. Results indicated that presoating of 0.6% or 0.9% H 2O 2 increased remarkably the rate, force and index of germination and made the plumule orderliness and haleness, at the same time, decreased the exosmosis of solubility protein and the rate of leakage of electrolyte of seeds;presoaking of 15×10 -6 inose and 0.5% KH 2PO 4 also increased the germination rate of seeds but did not affected distinctly other indexes.
