| 摘要: |
| 以吲哚丁酸IBA和ABT生根粉两种溶液的不同浓度处理及不同土壤基质处理分别对黄花倒水莲(Polygala fallax Hemsl.)扦插生根的影响进行试验研究。结果表明：吲哚丁酸IBA和ABT生根粉两种溶液的不同浓度处理对黄花倒水莲扦插根数、根长、稍长和生根率的影响均达到极显著水平,最佳浓度均为0.1g/L,生根率分别达到95%与90.4%,均极显著高于对照组；田园土+细河沙与黄心土+细河沙两种不同土壤基质处理对黄花倒水莲根数、根长、稍长及生根率的影响均达到极显著水平,效果最好的是黄心土+细河沙处理组,生根率达到91.6%,田园土+细河沙处理组效果次之,生根率为79.4%,均极显著高于对照组。 |

| Abstract: |
| The effects of different concentrations of ABT and IBA as well as different kinds of soil on Polygala fallax Hemsl. cuttings rooting .The results showed that there were significant level in the effects of different concentrations of ABT and IBA as well as different kinds of soil on Polygala fallax Hemsl. cuttings rooting . The best concentration was 0.1g/L both ABT and IBA. The rooting rate of them respectively reach 95% and 90.4%.The best soil was that yellow soil mixed with sand. Following closely was garden soil mixed with sand. The rooting rate of them respectively reach 91.6% and 79.4%. All of them were significantly higher than comparison. |
