| 摘 要： | 研究了华北石质山区不同郁闭度条件下野生黄连木5年生幼苗叶片的净光合速率、蒸腾速率、气孔导度、胞间CO2摩尔分数、气孔限制值、水分利用效率的光响应和CO2响应特征.结果表明:①幼苗叶片在不同郁闭度下的光响应过程基本相似,净光合速率都随着光合有效辐射强度的升高而增加,到达光饱和点后逐渐平缓.郁闭度0条件下,黄连木有较高的光...

| Abstract: | Light response and carbon dioxide response characteristics of net photosynthetic rate,transpiration rate,stomatal conductance,intercellular carbon dioxide concentration,stomatal limitation value and water use efficiency of leaves of 5-year-old wild Pistacia chinensis at different crown densities were observed in the rocky mountainous area of north China.Results showed that,at different crown densities,the seedlings were similar to each other in response to light,and net photosynthetic rate increased with in... |
