巴戟和鸡骨草的根系研究

调查研究了巴戟和鸡骨草两种药用植物根系的生长和分布与植株年龄、地上部生长及光照条件之间的关系。结果表明，随着植株年龄的增大，根系的生长和吸收中心逐渐下移，根生物量和根长垂直分布的变化反映了这种转移，地上部生长与根生物量有着显著相关性。荫蔽度是影响根系分布面积和深度的重要因素之一。文章还对这两种药用植物人工驯化栽培提出了意见。

STUDY ON THE ROOT SYSTEMS OF MORINDA OFFICINALIS AND ABRUS CANTONIENSIS

Based on the data obtained from survey in the field, growing and distributing characteristics of the root systems of Morinda officinalis and Abrus cantoniensis were reported. The age of plant, growth of ground parts and shady condition were the principal factors affected the growth and distribution of their root systems. The vertic distribution of biomass and root length of root system could indicate the centre of growth and absorption. According to their characteristics, some suggestions for developing production were put forward finally.
