| 摘 要： | 以海南槟榔为材料，采用不同浓度水平配比于槟榔花期、花果期、果期分别喷施的方法，研究IBA、GA、云大-120三种植物生长调节剂对槟榔座果率的影响。结果表明：IBA250mg／L、GA30mg／L、云大-1201000mg／L这3种处理水平在提高槟榔座果率上都达到显著或极显著影响。其中，IBA250mg／L处理较对照相比，达到极显著水平，GA30mg／L、云大-1201000mg／L较对照相比，达到显著水平。而其余6种处理水平，在提高槟榔座果率上效果不太明显。

| Abstract: | Three growth regulators, IBA, GA and Yunda-20, were sprayed at various concentrations onto betel nut (Areca catechu L.) during the flowering, flowering and fruiting, and fruiting stages. The results show that the IBA treatment at 250 mg/L improved fruiting rate highly significantly as compared to the control without spraying any regulator while the GA treatment at 30 mg/L and the Yunda-120 treatment at 1000 mg/L improved significantly the fruiting rate. The rest 6 treatments were not significant in improvin... |
