Abstract

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
