| 摘 要： | 对凉水地区白桦的光——光合特性进行了比较研究。结果表明：白桦幼树最大净光合速率与现观最大量子效率均大于幼苗；有性白桦（幼苗、幼树、成树）最大净光合速率、表马最大量子效率均大于无性白桦（幼苗、幼树、成树）；对于不同生境生长的白桦，以上2种光合指标，均为中生＞旱生＞湿生。 |
| 关 键 词： | 白桦 光合速率 表观量子效率 光饱和点 光补偿点 |

| Abstract: | Comparative study was proceeded in photosynthetic characteristics of birch in Liangshui region. The results showed that both maximum photosynthetic rate (Pg max) and apparent quantum yield (AQY) of young trees are higher than those of seedlings; both Pg max and AQY of sexual birch are higher than those of asexual birch (seedlings, young trees. adult trees); these two characteristics of birch growing in different habitats (mesophytic. xerophytic. hydrophytic habitat) were in the order of mesophytic> xerophytic> hydrophytic habitat. |
| Keywords: | Birch Photosynthetic rate Apparent quantum yield Light saturation point Light compensation point |
