- Plant photosynthesis can acclimate to the elevated CO2 and not keep a higher rate throughout the whole season. 植物的光合作用也存在对高CO2浓度的适应,不会一直维持较高的光合水平,而且植物的呼吸作用也可能会增加;
- As the material of photosynthesis of plant, elevated CO2 concentration must have an effect on photosynthesis of plant. CO2作为植物光合作用的底物，其浓度升高必然对植物的光合作用产生影响。
- Both tree species showed no photosynthetic acclimation to elevated CO2 concentration. CO2浓度升高条件下, 两树种均未发生光合适应现象。
- Elevated CO2 increased the dry mass of stem, branch, leaf and root and the uptake of N and P per plant, but decreased the N and P contents of each organ. CO2浓度增加,红桦幼苗茎枝、叶、根和总生物量提高,氮(N)、磷(P)含量降低,但单株N、P总吸收量均增加。
- The objective of this paper was to study the effects of elevated CO2 and different nutrient suppling intensity on growth and some physiological indices of tomato seedling. 营养液栽培条件下,研究了不同CO2浓度及养分供应强度对番茄幼苗生长及一些生理指标的影响。发现CO2施肥增加了株高、茎粗、整株的鲜干重,壮苗指数、叶片数、花蕾数、光合作用速率,胞间CO2浓度。
- This indicated that fertilizer application rate must be increased at later growth stage,furthermore,the application rater should be higher under elevated CO2. 说明在番茄育苗后期要增加施肥量,而且在CO2施肥的情况下施肥量增加的量要大。
