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:IBA 250mg/L、GA 30mg/L、云大-120 1000mg/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,IBA 250mg/L处理较对照相比,达到极显著水平,GA 30mg/L、云大-120 1000mg/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。
Three growth regulators, IBA, GA and Yunda-20, were sprayed at various concentrations onto betel nut （Areca cotechu 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 fi, uiting rate. The rest 6 treatments were not significant in improving the fruiting rate as against the control.
