摘 要 ：我们用NAA、IBA、IAA等植物生长调节剂促进多种园林植物插条发根的试验。结果表明：菊花、大丽花插枝，经0.1mg/L和0.2 mg/L NAA处理，具有促进发根的明显效果；0.1mg／L和0.2 mg/L的NAA和IBA处理较难发根的印度黄檀插枝，其发根率则有显著提高；月季、大叶黄杨、水杉、池杉、海南石梓等植物插枝，虽都具有较高的发根率，但经不同浓度NAA和IBA浸渍处理后，其发根率仍有不同程度的提高。

Abstract:Plant growth regulators NAA, IBA and IAA were applied for rooting of cuttings of several garden species. The experimental results showed that cuttings of Dendranthema morifolium and Dahia pinnota, treated with 0.1 mg/L and 0.2 mg/L NAA could increase rooting significantly. Dalbergia sissoo cuttings which were difficult in rooting, after treating with the above concentration of NAA and IBA rooting increased. Although Rosa chinensis, Euonymus megistophylla, Metaseguoia glyptostroboides, Taxodium ascendens and Gmelina hainanensis had high rate in rooting, but after treating their cuttings with different concentrations of NAA and IBA the rootings rates still could increase.
