不同年生林下参地上植株形态变异调查研究

Investigate and Discuss on the Morphological Variation of ground parts for Panax ginseng under Forest in the Different Growth Number of Year

本文对7年生和15年生林下参地上植株的形态变异情况进行调查。结果表明其茎高、茎粗、茎色、叶长、叶宽、叶色、叶柄长、小叶柄长、叶柄颜色、花轴长的地上植株形状均存在显著变异。由于环境的影响,同一年生林下参变异幅度很大,15年生林下参与7年生相比较,变异幅度更大。

This article studied on the morphological variation of ground parts for panax ginseng under forest of seven - year - old and fifteenth - year - old. the result show that there were obviously diference in stem height,stem diameter, stem color, leaf length, leaf width, leafstalk length and so on. because of environmental effect, there are larger disparity in the same growth number of year. compared the ginseng under forest 15 years with that of 7 years, the variation of the former is bigger than the later one
