摘要:
以辽阳灯塔市19个杨树品种为材料,研究了不同部位功能叶净光合速率、呼吸速率及其内在联系。结果表明,3930、中林46、盖杨净光合速率较高,天演、107、9317、辽河杨净光合速率较低,其余品种处于中间水平。9318、中林46、108呼吸速率较低,辽育1号、欧黑12、107、辽河杨、盖杨、中绥12较高,其余品种差别不大,并处在中间水平。辽育2号同枝不同部位功能叶片光合速率表现出由枝梢顶部向基部由大到小的变化趋势,不同方向功能叶片光合速率中,南部叶片最高,总体顺序为南>东>西>北。
Abstract:
This experiment studied on net photosynthetic rate%(Pn)% and dark respiration rate %(Rd)% in functional leaves of 19 poplar species.Among the different poplar species,%Pn% of 3930,Zhonglin 46 and Gaiyang are higher; Tianyan, 107, 9317 and Liaoheyang are lower;The other species are in middle. %Rd% of 9318,Zhonglin 46,108 are higher;Liaoyu 1、Ouhei 12、107、Liaoheyang are higher. The other are in middle.Comparising of net photosynthetic rate in functional leaves in different directions of Liaoyu 2,it shows that the south leaves are higher, the order is that south>east>west>north. From top to base in a shoot of Liaoyu 2, the variety current of Pn in functional leaves is from high to low.
