摘要: 运用LI-6400光合作用测定系统,对东北帽儿山地区白桦(Betula platyphyl la)种群的光-光合特性进行了比较研究。结果表明:白桦有性种群的实际光合能力和潜在光合能力均大于白桦无性种群(中生生境)(P < 0.05);中生生境白桦的光合能力大于湿生生境(有性种群)(P < 0.05);无论是有性种群还是无性种群,不同年龄(幼苗、幼树、成树)的白桦光合能力均以幼苗阶段最低且光补偿点最高(P < 0.05)。

关键词: 白桦, 生境, 有性种群, 无性种群, 光合特性

Abstract: Comparative study was processed in photosynthetic characteristics of birch in Maoershan region.The results showed:both the real photosynthetic capacity and the potential photosynthetic capacity of sexual birch are higher than those of a sexual birch (in mesophytic habit)(P < 0.05);the photosynthetic capacity of birch growing in mesophytic habit are higher than those of birch in hydrophytic habit (for sexual population)(P < 0.05);the photosynthetic capacity of seedlings is the lowest among birch in different ages while it also has the highest light compensation point no matter for sexual population or a sexual population (P < 0.05).

Key words: Birch, habits, sexual population, sexual population, photosynthetic characteristics
