摘　　要：The content of total sugar, sucrose, fructose and protein in the leaves of3-yr.-old Betula platyphylla was measured after the treatment by three exogenous sugar solutions(sucrose, fructose, glucose) and three high concentrations of CO_2 (700, 1 400, 2 100 μL/L·L^(-1))for about a month in 1998. The results showed that spraying three exogenous sugar solutionsincreased markedly the content of sugar and protein of leaves under 700 μL·L^(-1) and 1 400μL·L^(-1) CO_2 The effect of spraying exogenous sucrose solution was the best among the threeexogenous sugars. The treatment of spraying exogenous sugar solution and 2 100 μL·L^(-1) CO_2constrained the accumulation of total sugar and protein of leaves. There was no difference inprotein content of leaves when spraying glucose and fructose solutions under 700 μL·L^(-1) and 1400 μL·L^(-1) CO_2. The treatment of 2 100 μL·L^(-1) CO_2 concentration significantly increasedthe contents of total sugar, sucrose, fructose, and protein of leaves compared with that of the 700μL·L^(-1) and 1 400 μL·L^(-1) CO_2 except the plants spraying fructose solution. There waspositive correlation between the content of sugar of leaves and CO_2 concentration when sprayingsame exogenous sugar solution.3年生白桦同时接受3种外源糖溶液(蔗糖、果糖、葡萄糖)和3种高浓度CO2(700、1400、2100μLL-1CO2)处理。处理1个月后,测定了叶片的总糖、蔗糖、果糖和蛋白质含量。结果表明:在700μLL-1和1400μLL-1 CO2下,外源糖溶液增加了叶片的可溶性糖和蛋白质含量,其中外源蔗糖的效果最好;外源糖溶液与2100μLL-1CO2结合,会抑制叶片积累总糖和蛋白质;在700μLL-1和1400μLL-1CO2下,喷施葡萄糖、果糖的叶片在蛋白质含量上没有明显差别;;同700、1400μLL-1CO2相比,除喷施果糖植株外,2100μLL-1CO2明显增加了叶片的总糖、蔗糖、果糖和蛋白质含量;;在喷施同种外源糖溶液的情况下,叶片的糖含量与CO2浓度呈正相关性。图6参7。
