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

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.
