Four kinds of growth regulators could significantly improve the cuttings rooting index, the most significant effect on cutting was the treatment of IBA ( in-dole-3-butyric acid) , followed to IAA ( indole-3-acetic acid) , NAA ( 1-naphthylacetic acid) , and GA3 ( Gibberellin A3) , and the best rooting effect was the treatment with 500 mg/L IBA for 30 min. In addition, the suitability of cutting parts was studied via single factor experiment and the rooting type was also observed. The results showed that the highest rooting rate of different branch parts was the upper part and the rooting type of S. faeri cuttings was cortex rooting.收稿日期: 2020-09-18 引用本文: 吴永清，黄嘉琦，胡　秀，谭嘉川，汤　聪. 白花龙扦插繁殖研究[J]. 仲恺农业工程学院学报, 2018, 31(4): 30-34.链接本文: https://journal.zhku.edu.cn/CN/ 或 https://journal.zhku.edu.cn/CN/Y2018/V31/I4/30
