Abstract
The major short term stomatal response of A. deserti was to temperature; increases in leaf temperature led to decreases in water vapor conductance for stomatal opening during the daytime (C3 mode) and at night (Crassulacean acid metabolism or CAM mode). Hourly changes in the water vapor concentration drop from leaf to air had no significant stomatal effect in either mode. Stomatal responses to external CO2 levels up to 800 ml/l were not significant after 15 min and only moderate after a few hours, suggesting that CO2 effects on open stomates of this succulent were indirect in both CAM and C3 modes.This publication has 6 references indexed in Scilit:
