| 摘 要： | 利用Lico-6400便携式光合测定仪,研究了30个毛白杨无性系光合指标的变化,并对环境因子与光合指标相关关系进行了探讨.结果表明:毛白杨无性系的净光合速率(Pn)、气孔导度(Gs)、蒸腾速率(Tr)日变化均呈典型双峰曲线,气孔限制是出现"午休"现象的主要调节因素,胞间CO2浓度(Ci)日变化曲线呈典型的"V"字型.5... |

| Abstract: | The photosynthetic characteristics of 30 Populus tomentosa clones were measured with lico-6400 photosynthetic instrument,and the relationship between the environmental factors and physiological indicators was studied by correlation analysis and stepwise regression equation.The results showed that the diurnal net photosynthesis rate(Pn) variation of P.tomentosa clones presented a typical double-peak curve,and that stomatal limitation was a major regulatory factor of decreased photosynthesis.The Pn-Par(photos... |
| Keywords: | Populus tomentosa clone photosynthetic rate variation |
