Abstract:
4-year-old seedlings and 15-year-old saplings of Taxus cuspidate were used as test materials.By measuring chlorophyll fluorescence kinetics and comparing photosynthetic response of PSⅡ in seedling and sapling leaves of Taxus cuspidate after high light stress,the physiological and functional changes of PSⅡ in seedling and sapling leaves of Taxus cuspidata were analyzed after removing shade.It revealed the responses of seedling and sapling leaves of Taxus cuspidata to high light and provided a theoretical basis for the light regulation in artificial cultivation of Taxus cuspidate.The results showed that high light stress caused decrease in Fv/Fm of seedlings and saplings of Taxus cuspidata,which indicated that photoinhibition occurred.But the degree of photoinhibition on sapling leaves was less than that on seedling leaves.The increases of VJ in seedlings and saplings of Taxus cuspidata indicated that acceptor sides of PSⅡ were damaged by high light stress and the capacity of PQ have been changed.The Ψo and ETo/RC in seedlings and saplings of Taxus cuspidata decreased.On the other hand,φDo and DIo/RC in seedlings and saplings of Taxus cuspidata increased,which showed that leaves could protect photosynthetic apparatus by increasing thermal dissipation under high light.After high light stress,the leaves of sapling had more energy for electron transfer in PSⅡ and less energy for dissipation than seedling leaves,and photosynthetic activity per reaction center of sapling leaves were damaged less than seedling leaves.In conclusion,high light could damage PSⅡ in seedling and sapling leaves of Taxus cuspidata after removing shade.However,light resistance of sapling was significantly higher than that of seedlings.Shade and shelter for the artificial cultivation of Taxus cuspidata seedling should deserve attention.
