摘      要：Plants of the genus Camellia are widely cultivated throughout the world as ornamentals because of their bright and large *** widely cultivated varieties are mainly derived from the mutant lines and hybrid progenies of Camellia japonica *** Camellia reticulata *** their geographical distributions and environmental adaptabilities are significantly different,no systematic comparison has been conducted between these two *** investigate differences in how these plants have adapted to their environments,we measured photosynthesis and 20 leaf functional traits of *** and *** grown under the same *** with ***,*** showed higher values for light saturation point,light-saturated photo synthetic rate,leaf dry mass per unit area and stomatal area,but lower values for apparent quantum efficiency,leaf size,stomatal density and leaf nitrogen content per unit *** area was positively correlated with light-saturated photosynthetic rate and light saturation point,but negatively correlated with stomatal *** differences between *** and *** were mainly reflected in their adaptations to light intensity and leaf morphological *** is better adapted to high light intensity than *** difference is related to the two species’ differing life fo ***,leaf morphological traits have played an important role in the light adaptation of *** and ***,and might be first noticed and selected during the breeding *** findings will contribute to the cultivation of camellia plants.
