摘要
夏枯草Prunella vulgaris为唇形科夏枯草属多年生草本植物,以干燥果穗入药,为我国常用中药材。采用野外环境因子调查、室内分解测定和统计分析方法,为夏枯草野生资源保护和人工栽培提供参考依据,对不同居群夏枯草产量构成因子与形态特征关系研究;结果表明不同环境中夏枯草产量的贡献因子不同,在适宜环境中,夏枯草的叶长、叶数、株高、生殖枝数对夏枯草的产量贡献最大;在过渡环境中,夏枯草的茎直径、叶长、穗直径对产量的贡献较大;在林下和干旱环境中,影响夏枯草的产量构成因子主要是根长、叶宽、穗长等。
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.keywords：Prunella vulgaris
