Abstract:
Taking 7 years old potcultured Ginkgo biloba L.seedling as test material，the photosynthesis and fluorescence characteristics of Ginkgo biloba L.shoots leaves were studied，the chlorophyll contents，photosynthesis and fluorescence parameters were measured.The results showed that,compared with perennial branches leaves，the chlorophyll contents in shoots leaves was lower but chlorophyll a/b in contrast.At the same time，the shoots leaves also had a higher photosynthesis rate(Pn).The diurnal variation of photosynthesis in shoots leaves had a ‘midday depression’ phenomenon，it mainly due to stomatal factors；on the other hand，fluorescence parameters showed that shoots leaves with high quantum yield of primary photochemistry（Fv/Fm）and conformation term for primary photochemistry（Fv/F0）.
