茅苍术资源再生的研究

DYNAMICS IN THE RESOURCE REPRODUCTION OF ATRACTYLODES LANCEA (THUNB.) DC.

  • 摘要: 通过对茅苍术Atracty lodeslancea(Thunb.)DC.有性繁殖及营养繁殖后代的研究,论述其资源再生的若干生物学特性的基本规律。结果表明,茅苍术在根茎形态、干物质量、化学成分的种类和含量上都随年龄有一定的动态变化规律,并存在个体差异。繁殖方式对干物质量的增长速率无明显影响。根茎中挥发油成分的含量随年龄的变化有一下降后再缓慢增加的趋势。同时还讨论了两种繁殖方式在茅苍术生产中的意义。

     

    Abstract: Seedlings and vegetatively propagated offsprings of A.lancea,a Chinese traditional medicine"Cangzhu",were researched in order to understand their biological characteristics and the mechanism of the resource reproduction.It was proved that with the changes of age, the plant presented a series of developmental improvements on rhizome morphology, dry weight and the composition of chemical components, although variations have been found among individual plants. Propagation methods showed no distinct actions on the increasing rate of the dry weight of rhizomes.The amounts of the components of volatile oil in rhizomes firstly decreased and then increased very slowly with aging.The significances of two propagation methods on the cultivation of Cangzhu and its resource reproduction were also discussed.
