摘　　要：试验比较了低浓度（1g·L-1）与高浓度（5～50g·L-1）蔗糖对黄瓜不定根发生的作用。结果表明：不同浓度的蔗糖对植株不定根发生的影响差异显著，低浓度蔗糖能明显促进黄瓜下胚轴切段不定根发生，而高浓度蔗糖则不同程度抑制不定根的发生。The effects of low concentration （1 g ·L-1） and higher concentration （5-50 g·L-1） of sucrose on initiation and growth of adventitious roots of cucumbers （ Cucumis sativus L. ） were compared. In our experimental conditions, there existed sig- nificant differences among the effects of varying concentration of sucrose on adventitious rooting process. For example, low concen- tration of sucrose was able to induce the development of adventitious root obviously, whereas higher concentrations of sucrose exhibi- ted the differential inhibitory effects.
