摘要：

Chlorophyll concentrations and rates of photosynthetic O2 evolution were measured in Dicranum scoparium, Leucobryum glaucum, and Thuidium delicatulum collected from a forest understory in northeastern Kansas. In all species photosynthesis saturated around 200-mu-mol m-2 sec.-1, reflecting the intermediate nature of sun-shade adaptation in these species. The highest concentration of chlorophyll was found in L. glaucum and correlated with higher rates of photosynthesis at low light levels. These findings lend support to the expectation that higher chlorophyll concentrations in mosses will enhance light capture at low light levels.
