山西太岳山辽东栎的光合特性

For the needs of evaluation of the reflection tendency of Quercus liaotungensis under the depression of greenhouse effect. The comparisons of photosynthesis characteristic in normal and controlled situations have been taken. the main elements as photosynthesis active radiation ( PAR ),CO 2 concentration(CO 2),air temperature( Ta ),leaf temperature( Tl) et al have be Measured and logged by Li 6400 portable photosynthesis system. While the photosynthesis rate ( Pn ), transpiration rate,stomo...
