摘要
[目的]研究三角梅最佳扦插生根技术。[方法]以盆栽三角梅当年生健壮无病虫害的半木质化枝条为试材。先进行泥炭、珍珠岩、蛭石不同基质配比试验,以找出最佳三角梅扦插基质,再分别进行春季、夏季、秋季不同采穗时间,ABT1号、IBA、NAA不同浓度处理扦插试验。[结果]扦插时间适宜在夏季(6月25日左右),采用泥炭∶珍珠岩=2∶1作为扦插基质、300 mg/L ABT1号处理插穗30 min效果最佳。[结论]该研究可为探索三角梅无性繁殖的扦插技术提供参考。
[Objective]To study the cutting propagation technology of Bougainvillea glabra. [Method]The experiment was conducted with the semi-wooded branches of B. glabra that were robust and free from diseases and pests.In order to find the best cuttage medium for B. glabra, the experiments of peat, perlite and vermiculite were carried out at first.Cutting experiments were carried out next in spring, summer and autumn with different cutting time, different concentrations of ABT1, IBA and NAA.[Result]Cutting time was suitable for summer （June 25 or so）. Peat ∶perlite=2 ∶1 as cutting medium, 300 mg/L ABT1 treatment for 30 minutes were the best.[Conclusion]This study can provide reference for exploring cuttage techniques of asexual propagation of B. glabra.
