摘　　要：不同的物理、化学法催芽处理可以改善美女樱种子发芽。外源赤霉素(GA3)和6-BA溶液浸种处理,低浓度促进发芽、而高浓度抑制发芽。赤霉素(GA3)和6-BA适宜浓度分别为20 mg?L?1和10 mg?L?1。低温高湿沙基层积处理20 d、30%过氧化氢(H2O2)浸种处理10 min、50℃热水浸种处理8  h,其发芽率分别比对照组提高58.48%、64.11%和61.06%,与对照组差异达到极显著水平(p 【0.01),催芽效果显著。Different physical and chemical germination treatments could improve the germination of Verbena hybrida seeds. Gibberellin (GA3) and 6-BA solution were soaked, low concentration promoted germination, and high concentration inhibited germination. The appropriate concentrations of gibberellin (GA3) and 6-BA were 20 mg?L?1 and 10 mg?L?1, respectively. As for the low temperature and high humidity sand substrate treatment for 20 d, 30% hydrogen peroxide (H2O2) soaking treatment for 10 min, 50°C hot water soaking treatment for 8 h, the germination rate was 58.48%, 64.11% and 61.06%, respectively, compared with the control group. A very significant level (p
