Effect of elevated CO2 on the stomatal distribution and leaf physiology of Alnus glutinosa.

摘要: Variation in stomatal development and physiology of mature leaves from Alnus glutinosa plants grown under reference (current ambient, 360 μmol mol−1 CO2) double ambient (720 carbon dioxide (CO2) mole fractions is assessed terms relative plant growth, characters (i.e. index density) leaf photosynthetic characters. This the first study to consider effects elevated CO2 concentration on distribution stomata epidermal cells across whole try ascertain cause intraleaf variation. In general, a doubling atmospheric enhanced growth significantly increased index. However, there was no significant change density. Under decrease conductance an increase assimilation rate. differences were found for maximum rate carboxylation (Vcmax) light saturated electron transport (Jmax) between control treatment.
