| 摘 要： | 以2年生母树上当年生半木质化嫩枝为材料，采用L9 3^4正交试验设计，研究吲哚丁酸（IBA）、萘乙酸（NAA）及其组合对红缨海棠嫩枝扦插生根的影响。结果表明：红缨海棠嫩枝扦插生根类型为愈伤组织生根型；生根剂处理可以显著促进插穗生根，萘乙酸（NAA）对插穗生根的促进作用明显优于吲哚丁酸（IBA），且插穗生根质量较好；用1000mg／LNAA溶液浸蘸插穗5s，生根率可达70％。

| Abstract: | Taking semi-lignified cuttings obtained from 2-year-old maternal trees of Malus ＇ Hongying＇ as experiment materials, the effect of different plant growth regulators including IBA, NAA, and IBA ＋ NAA on the rooting was studied by using uniform orthogonal design L9 34. The results showed that the rooting type of Malus ＇ Hongying＇ tender cuttings mainly belonged to callus rooting, the treatment by plant growth regulators could significantly increase the rooting rate of the semi-lignified cuttings. The rooting promotion effect of NAA was better than IBA. The rooting rate reached 70 % when the semi-lignified cuttings were soaked by 1 000 mg/L NAA for 5 s. |
