摘要

本試驗之主要目的在探討不同種類及濃度之生長調節劑，對不同生育期的薜荔插穗發根之效應。結果顯示不同生育期之插穗其不定根發生隨生理年齡之增加而減弱，以幼年期發根最佳，轉變期次之而成年期幾乎不發根。IBA處理插穗基部可促進不定根之發生，但對成年期插穗不定根發生之改善則效果不明顯。不同生長調節劑除了Ethrel對不定根之發生有不利之影響外，IAA及GA對沒有處理發根劑之成年插穗則稍有促進效果，IAA、GA、BA及ABA在IBA處理之配合下也對成年插穗之發根稍有改進。

The purpose of this experiment was to understand the influence of different kinds and concentrations of plant growth regulators at the adventitious root formation in different physiological stage cuttings of Ficus pumila L..The adventitious root formation in different physiological stage cuttings of Ficus pumila L. decreased when the plant was aged gradually. The juvenile phase showed the best result in adventitious root formation, the adult phase almost no adventitious root formation, and the transitional phase was between them. IBA increased the adventitious root formation, but gave poor result for the adult phase. Ethrel inhibited the adventitious root formation for all three phases. IAA and GA had a little effectiveness in the adult phase without IBA added. IAA, GA, BA and ABA also had some effectiveness in the adult phase with IBA added.
