野生和栽培防风根系的比较形态解剖学研究

STUDY ON COMPARING MORPHOLOGY AND ANATOMY OF ROOTS SYSTEM OF WILD AND CULTIVATED SAPOSHNIKOVIA DIVARICATA

研究了野生和栽培防风根系的外部形态及内部结构，研究结果表明：在外部形态上，栽培防风根系颜色较浅，侧根较多。在内部结构上，二者大致相同。二年生栽培防风主根与野生多年生防风主根中油室数目、韧皮部／木质部相近，建议生产上适当采收二年生植株根系。

This paper studied the external morphology and internal structure of the wild and cultivated Saposhnikovia divaricata . The results indicated: the colour of cultivated roots are pale yellow and have many lateral roots. The wild and cultivated Saposhnikovia divaricata have the same internal structute, there are similar number of oil canal and same ratio of phloem to xylem in the perienial wild and two years cultivated Saposhnikovia divaricata. We suggested that the two years cultivated Saposhnikovia divaricta can be used in production.
