| [photosynthetic characteristics of five arbor species in shenyang urban area]. | by using li-6400 infrared gas analyzer, this paper studied the diurnal and seasonal variations of the photosynthetic rate of main arbor species (populus alba x p. berolinensis, salix matsudana, ulmus pumila, robinia pseudoacacia and prunus davidiana) in shenyang urban area. the correlations between net photosynthetic rate and environmental factors (photosynthetic active radiation, temperature, and stomatal conductance) were assessed by multivariate regression analysis, and related equations were ... | 2007 | 17974233 |
