摘 要：
采用Li-6400便携式光合测定仪,对福建沙县引种的银杏、半枫荷、枫香、黄山栾、蓝果树、北美红枫、红叶李、无患子、海棠和碧桃等10种彩叶树种的净光合速率和蒸腾速率进行测定。结果表明:(1)银杏、蓝果树、红叶李和碧桃净光合速率的日变化呈单峰曲线;而半枫荷、枫香、黄山栾、北美红枫、无患子和海棠则呈双峰曲线,观察到"午休"现象。银杏、黄山栾、蓝果树、红叶李和碧桃蒸腾速率的日变化呈单峰曲线;而半枫荷、枫香、北美红枫和海棠呈双峰曲线。(2)海棠的日蒸腾速率最大(3.73 mmol·m~(-2)·s~(-1)),蓝果树的最小(2.03 mmol·m~(-2)·s~(-1)),是海棠的54.43%。(3)无患子、碧桃和海棠节水能力明显高于其他树种。

摘 要：
The net photosynthetic rate & transpiration rate of 10 colored-leaved tree species( Ginkgo biloba,Semiliquidambar cathayensis, Liquidambar formosana, Koelreuteria bipinnata, Nyssa sinensis,Acer rubrum, Prunus cerasifera,Sapindus mukorossi,Malus spectabilis & Amygdalus persica) which were introduced in Shaxian County of Fujian Province were measured by LI-6400 portable photosynthetic meter. Results showed that:(1) The diurnal variation of net photosynthetic rate of Ginkgo biloba, Nyssa sinensis, Prunus cerasifera,Sapindus mukorossi,Malus spectabilis and Amygdalus persica show single peak curve, while the diurnal variation of net photosynthetic rate of Semiliquidambar cathayensis, Liquidambar formosana, Koelreuteria bipinnata, Acer rubrum, Sapindus mukorossi & Malus spectabilis show double peak curve, and the phenomenon of "nap break" was observed.The diurnal variation of transpiration rate of Ginkgo biloba, Koelreuteria bipinnata, Nyssa sinensis, Prunus cerasifera and Amygdalus persica show unimodal curve, while the diurnal variation of transpiration rate of Semiliquidambar cathayensis, Liquidambar formosana, Acer rubrum and Malus spectabilis show bimodal curve.(2) Malus spectabilis have the highest daily transpiration rate(3.73 mmol·m~(-2)·s~(-1)),and Nyssa sinensis have the lowest daily transpiration rate(2.03 mmol·m~(-2)·s~(-1)),which is 54.43% of Malus spectabilis.(3) Analysis of the water use efficiency of 10 tree species with colored leaves show that the water saving ability of the species with Sapindus mukorossi,Amygdalus persica & Malus spectabilis is significantly higher than that of other tree species.
