The activities of key enzymes in C4 plants,such as PEP carboxylase and pyruvate phosphate dikinase(PPDK) were very low in Cymbidium sinense, however, the activity of RuBP carboxylase was high. The activity of glycolate oxidase in the leaf was rather high. The glycolate content in the leaf increased when the leaf was treated with α-hydroxypyridyl methyl sulfonate(α-HPMS) under light. The ratio of Chl. a/b was between 2.6-2.7. In CO2-free air, the CO2 evolution of the leaf under light was high. All the above mentioned results suggested that Cymbidium sinense is a C3 species.
