  Ginkgo (Ginkgo biloba) is often subjected to drought during its growth season.However,little is known about the physiological mechanisms underlying changes in the photochemical activities of PSⅡ in Gingko.In this study, we analyzed changes in the fluorescence characteristics of PSⅡ in chloroplasts of mesophyll cells in drought-stressed leaves of the G.biloba cultivar Taixingdafuzhi.Five-year-old ginkgo trees were grown in pots in a greenhouse and subjected to one of four drought treatments (20, 30, 40 or 50 days without watering) and compared with control trees (0 days without watering).
