Morphological Characteristics and Taxonomy of Glycyrrhiza uralensis Fisch.Germplasm Resources from Different Production Areas
摘要
Abstract
As one of the commonly used medicinal herbs in China,the quality problems of Glycyrrhiza uralensisis prevalent due to the confusion of place of origin.Therefore,the research on G.uralensis.germplasm resources is of great con-cern.In this paper,14 species of G.uralensis.plants planted in the same locus were used as the observation object,and the possibility of classification of G.uralensis.species was discussed based on 20 quantitative charactersand 7 discrete traits.The re-sults showed that there were significant differences among the 18 quantitative charactersof 14 species of G.uralensis.except the internode length and infructescence actual length /infructescence stalk length in the same geographical environment,not only the geographical distance clustering.Inner Mongolia,Ningxia and Shaanxi at the junction of the five place of origin were still maintained,but the remaining nine geopolitics relations were broken.The characters with taxonomic significance were plant height,infructescence stalk length,leaflet width,infructescence width,infructescence actual length /infructescence width, plant height /plant width,leaflet upper limit,leaf length,leaf tip shape and so on.It is proved that there are abundant varia-tions in G.uralensis Fisch.species,and further classification should be carried out.The taxonomy value of plant height and or-der length is higher than the others.关键词
