摘要

外接indole butyric acid（IBA）對date Palm切莖之發根情形具明顯的正效果。和控制組對照，經IBA處理後，切莖發根較早、較頻、較多。外加之IBA（乃植物生長素auxin之一形式）之效果除了外觀性狀如發根之外，也反映在發根過程之代謝改變。過氧化酵素活性在IBA處理後第6天最低而第12天時最高。IAA氧化酵素之活性變化也有相似之時間曲線，而酚類含量及auxin保護成份之水位顯示相反之時間變化。控制組則一星期後才有微小的變化。

Exogenous indole butyric acid had a significant positive effect on the rooting response of date Palm (Phoenix dactylifera L.) offshoots. IBA-treated offshoots rooted earlier and with a much higher frequency while untreated offshoots rooted poorly, later, and tended to produce fewer roots. The effect of exogenous application of auxin was also reflected in the metabolic changes in offshoots during the rooting process. Pox activity showed a minimum on the sixth day and a maximum on the twelfth day after the root-inducing treatment. Changes of IAA oxidase activity showed a parallel time curve while phenolic contents and auxin protector levels showed an inverse trend. These parameters changed slightly one week later in the untreated offshoots.
