摘要：
Photosynthetic pigments, biochemical activities and chlorophyll a fluorescence kinetics were investigated to survey the photosynthetic characteristics of Ginkgo biloba L. during leaf growth. The content of total chlorophyll increased rapidly while the content of carotenoids changed a little. The content of ATP, the activity of O-2 evolution of chloroplasts, the electron transport activities, the activity of photophosphorylation and the activities of Ca2+ - and Me2+ - ATPase were strengthened. All leaves at various growing stages exhibited typical chlorophyll a fluorescence transient, the intensity of fluorescence in the chlorophyll a fluorescence transient (OJIP) increased during leaf growth. Photosynthetic abilities gradually increased as the leaves grew.
