Abstract Stomata control carbon and water vapor exchange between the leaves atmosphere, thus influencing photosynthesis transpiration. Combinations of forest patches with different stand ages are common in nature, however, information which stomatal traits vary among these stands how, remains limited. Here, seven aged (6, 14, 25, 36, 45, 55, 100 years) were selected typical temperate, mixed broadleaf-conifer forests northeast China. Stomatal density, size relative area 624 species, including same species selected. distributed log-normally, differing across all plant functional groups. density ranged from 4.2 to 1276.7 stomata mm –2 , 66.6 8315.7 μm 2 0.1–93.3%. There was a significant negative relationship at group levels, while positively correlated size. dominant relatively stable but significantly for herbs. The results suggest that remain natural therefore, spatial variation does not need be incorporated future ecological models.
