不同杨树不同层面净光合速率差异及贡献率的研究
Study on the Photosynthetic Net Rate and Contribution Rate at Different Layers of Various Poplars
摘要
Abstract
The experiment used ten types annual poplars'as the materials, and the photosynthetic rate and stomatal con-ductance(G,) were tested by the portable photosynthesis system. The result showed that: Ⅲ-4-2,Ⅲ-1-18 and Ⅱ-1-3 had the largest photosynthetic contribution rate focused in the middle layer and the others in the top layer. The G, and net photosynthetic rate( Pn) showed positive correlation.关键词
