The results showed that the stomatal density in Eucommia ulmoides, Quercus liaotungensis and Q. glandulifera% var. brevipetiolata decreased significantly in response to the elevated atmospheric CO-2 concentrations, while in Cyclocarya paliurus it decreased slightly and in Ficus heteromorpha there were no responses. 关键词：WOODY PLANTS STOMATAL DENSITY ATMOSPHERIC CO-2 concentrations.
