Description
Smith (1971) had determined the delta13C for plant tissue from 104 species representing 60 families. Higher plants fall into two categories, those (C3) with low delta13C value ( 24 %to 34 %), those (C4) with high delta13C values ( 6 % to 19 %). Now this method and its theoretical basis for plant fractionation were developed by many studies (O'Leary, 1981 ; Farquhar et al., 1982), and extensively applied to the domain of the ecology (Tieszen, 1987). In this paper, the delta 13C values of plants were determined by spectrometer and C3 or C4 photosynthetic type was discriminated for 27 species collected from grasslands, and the discriminative methods of C3 and C4 plants are discussed.
