| 摘 要： | 以稳定性碳同位素比(δ13C)鉴别禾本科、莎草科、苋科和萝摩科共46种植物的光合作用途径,发现了36种新的C4植物(δ13C-10.43到-13.66‰)和1种CAM植物(δ13C-15.24‰)。根据Hattersley区分C4植物三种亚类型的不同δ13C值,提出在36种C4中有8种具δ13C值-10.4到-10.9‰者是NADP-ME型,6种具δ13C值-13‰左右的是NAD-ME型,其余种类可能是NADP-ME或PCK型。

| Abstract: | The identification of the photosynthetic pathway of 46 species from the Poaceae, Cypcraceae, Amaranthaceae and Asclepiadaceae were made using stable carbon isotope ratio measurements. 36 species showed the δ13C value of -10.43 to -13.66‰ and 1 species with succulent leaves had aδ13C value of -15.24‰. It is suggested that these species are new C4 and CAM type plants, respectively.According to the mean δ13C value of three C4 suhtypes proposed hy Hatteraley, it is possible that 8 species with δ13C value of -10.4 to -10.9‰ are NADP-ME type, and 6 species with δ13C value of-13‰ may be the NAD-ME type. The others will be NADP-ME or PCK type. |
