E. KRIEDEMANN,2 B. R. LOVEYS, G. L. FULLER, AND A. C. LEOPOLD Department of Horticulture, Purdue University, Lafayette, Indiana 47907 ABSTRACT The closure of stomata by abscisic acid was examined in several species of plants through measurements of C02 and Stomatal Response to Humidity: Blurring the Boundary between Active and Passive Movement, Surviving a Dry Future: Abscisic Acid (ABA)-Mediated Plant Mechanisms for Conserving Water under Low Humidity. Stomatal regulation 1. The effect of leaf water deficit on net CO 2 assimilation was studied under two conditions: in one, the stomata were allowed to contribute to the regulation of CO 2 assimilation; in the other, air was forced through the leaf at a constant rate to overcome the effects of change in stomatal resistance accompanying changes in leaf water deficit. Evidence for the regulation of stomatal conductance by hydraulic and chemical signals is presented in the second section. V. Environmental control of abscisic acid accumulation and stomatal sensitivity to abscisic acid. endobj The relationship between stomatal conductance (g s) and leaf water potential (Ψ l) is key to the understanding of plant function under changing climate.The variability among tree species gave rise to selection towards either of two contrasting water management types: isohydric or anisohydric. Background: stomatal water relations 22 III. The circadian clock is a molecular timer of metabolism that affects the diurnal pattern of stomatal conductance (gs), amongst other processes, in a broad array of plant species. stomatal development. water status by modifying stomatal conductance using a range of strategies: from isohydric—relatively con-stant leaf water potential actively maintained by stomatal regulation—to anisohydric—minimal stomatal regulation resulting in varying leaf water potential typically driven by the balance of water supply to the leaf and atmospheric demand.
