山西野生黄芩资源及其生长环境研究

Study on Germplasm Resource and Growth Environment of Wild Scutellaria baicalensis in Shanxi

研究了山西省6个市所辖15个县(市、区)的野生黄芩的分布、生长环境以及不同生境下的植物形态特征。山西野生黄芩的群落组成主要为连翘、黄刺玫、蒲公英、沙棘、委陵菜、唐松草、藜等,在不同的生长地区还伴生有当地的优势物种。由于不同地区间野生黄芩生长环境的不同,其形态特征也有所差异。山西南部地区的野生黄芩普遍较中部地区的植株高大,形态学指标整体上表现较好。研究结果可为了解山西野生黄芩资源的分布及其不同产地的植物学性状,进而选育适宜不同地区气候条件的家种品种提供依据。

The distribution, growth environment and plant morphology of wild Scutellaria baica!ensis in 15 counties under the jurisdiction of 6 cities in Shanxi province were studied. The community composition of wild S. baicalensis in Shanxi was mainly forsythia, yellow thorn, dandelion, seabuckthorn, potentilla, Tang herbs, quinoa, et al, and different growing areas are also associated with local dominant plants. Due to the different growth environment of wild Scutellaria baicalensis in different regions, the morphological characteristics are different. The wild S. baicalensis in the southern part of Shanxi province is generally higher than that in the middle area, and the morphological index is better. The results provide a basis for understanding the distribution of wild S. baicalensis resources in Shanxi and the botanical traits of different origin, and then breeding the varieties suitable for different regional climatic conditions.
