摘要/Abstract

摘要： 以大白杜鹃（Rhododendron decorum）、百合花杜鹃（R. liliiflorum）和云南杜鹃（R. yunnanense）种子作为实验材料,经不同浓度的赤霉素（GA3）溶液浸泡24后播种至红土、营养土和农田土3种基质上进行漂浮育苗实验,探究杜鹃属（Rhododendron）植物种子繁育的有效方法,为杜鹃属植物种子繁育提供参考。结果表明,在大白杜鹃、百合花杜鹃和云南杜鹃的漂浮育苗过程中,100mg·L^-1是处理种子的最适赤霉素浓度,处理时间24h;营养土相比红土和农田土更适合杜鹃花的漂浮育苗;不同杜鹃属植物在漂浮育苗过程中的生长状况有所不同,但都成功获得的健康幼苗。

关键词: 杜鹃花, 赤霉素, 土壤, 漂浮育苗

Abstract: The seeds of Rhododendron decorum,R. liliflorum and R. yunnanense were used as experimental materials, soaked in gibberellin (GA3) solutions of different concentrations for 24 hours and then inoculated into laterite. Floating garden experiments were carried out on three substrates, laterite, nutrient soil and farmland soil to explore an effective method for seed propagation of Rhododendron, and provide reference for Rhododendron seed propagation. The results show that in the floating seedling process of R. decorum, R. liliiflorum and R. yunnanense, 100 mg·L^-1 is the optimum concentration of gibberellin to treat seeds, and the treatment time is 24 h; nutrient soil is more suitable for Rhododendron than laterite and farmland soil. Seedlings of different Rhododendron species vary in condition during reproduction, but all successfully obtained healthy seedlings.

Key words: Rhododendron, gibberellin, soil, Floating Garden
