摘要
应用LI-6400光合分析仪对西部沙樱、针叶樱桃等几个引进树种的净光合速率、气孔导度、胞间CO2浓度和蒸腾速率等光合参数指标进行了测定分析,旨在为各树种在辽西地区的适应能力和综合表现研究提供依据。
With the help of the photosynthetic analyzer, photosynthetic parameters including the net photosynthetic rate, the stomatal conductance, the intercellular C02 concentration and the transpira- tion rate of several exotic trees are analyzed, providing the basis for the study of the adaptive ability and the comprehensive performance of the exotic trees in western Liaoning Province.
