Factor of Prunella vulgaris yield components and morphological characteristics of relationship in different populations / 中国中药杂志

ABSTRACT

Prunella vulgaris is a perennial herb whose dry spike is used for medicine in China. It is also a very important traditional medicine. Current study was conducted to the biomass components factors of P. vulgaris in the different ecological environments for the development and protection. The results showed that the contribution factor of the production in different environments was significant differences. In favorable environment, the length of leaf, numbers of leaves, height, reproductive branch number of individuals gave the greatest contribution. In transitional habitats, the diameter of stem and spike, the length of leaf contributed the most. While in the undergrowth and dry hillside, the length of root, the width of leaf, the length of spike were the main factors for biomass.
