Identification of the Photosynthetic Pathways of 30 Plant Species in the Subalpine Meadow of the Qinling Mountains,China

摘要: 利用形态解剖法和模型判别分析法,对秦岭亚高山草甸的30种草本植物的C₃、C₄光合作用途径进行了鉴定。两种方法的结果有差异,但综合认为解剖的结果更为客观。在15科25属30种植物中,共鉴定出7种C4植物,属于6科7属,分别为细茎橐吾(Ligularia hookeri(C.B.Clarke)Hand.-Mazz.)、太白蓼(Polygonum taipaisha-nense Kung)、藜芦(Veratrum nigrum)、东方草莓(Fragaria orientalis)、粗边扁蕾(Gentianopsis scabromarginata)、假报春(Cortusa pekinensis),耳叶蟹甲草(Parasenecio auriculata)。

Abstract: The photosynthetic pathways of 30 plant species in the subalpine meadow of the Qinling Mountains using discriminant analysis model and anatomy methodology.Of the total 30 species,7 species belonging to 7 genera and 6 families were C₄ species,they were Ligularia hookeri,Polygonum taipaishanense,Veratrum nigrum,Fragaria orientalis,Gentianopsis scabromarginata,Cortusa pekinensis and Parasenecio auriculata.There was disparity between the two methods,but the results of the anatomy method seem much convincing.
