| 摘 要： | 厚朴(Magnolia officinalis Rehd. et Wils.)为木兰科(Magnoliaceae)落叶乔木.正品药用厚朴为厚朴的根皮、干皮和枝皮,其中的有效成分(厚朴酚(magnolol)、和厚朴酚(honokiol)及β-桉叶油醇等)具有多方面的药理作用(如燥湿消痰、下气除满),用于湿滞伤中、脱痞吐泻、食积气滞、腹胀便秘、痰饮喘咳等1-4].厚朴主要分布于102NFA48122°E、22NFA4834°N之间,分布区内的不同气候及土壤条件,致使形成大量不同的遗传类型,其中种子形态必然存在很大的差异. |

| Abstract: | The length, width, thickness, length/width ratio and 100-seed weight of Magnolia officinalis seeds from 15 natural distribution regions in China were measured and their germination rates were tested. The results showed that there were significant differences among seeds from different region in seed characters and 100-seed weight. Correlation analysis between seed characters and geographical climatic factors showed that the main variation was of geographical locations. The annual mean temperature, annual precipitation and frost-free period were the leading ecological factors restricting the seed variation. The results of test showed that there were significant differences in germination rates among different seed sources. The seeds from Ningqiang had the highest germination rate, while that from Kaixian the minimum. The seeds from Jingning, Wuyishan and Longsheng had high germination potential. According to cluster analysis on 5 trait-location mean values including seed size and quality and geographical climatic factors, the Magnolia officinalis from 15 natural distribution regions could be divided into 2 provenance regions, i.e. south-east M. officinalis provenance region and north-west provenance region. |
