Abstract

Abstract:

Planting trials of seedling types and spacing were conducted for RauwoIfia yunnanensis,and effects of seedling types and spacing on its growth and yield were investigated.The results showed that cuttings should be applied in the practice rather than seedling of R.yunnanensis due to their easy cultivation and few individual variation,although significant difference in growth and yield was absent between them in the present study.There were significant differences in growth and yield of R.yunnanensis among six spacing treatments,and the yield of stems and leaves as well as roots performed the best for spacing 0.4 m×1.0 m.

Key words: RauwoIfia yunnanensis, seedling types, spacing, growth performance, root yield
