Pragmatic hydraulic theory predicts stomatal responses to climatic water deficits.
Ecosystem models have difficulty predicting plant drought responses, partially from uncertainty in the stomatal response to water deficits in soil and atmosphere. We evaluate a 'supply-demand' theory for water-limited stomatal behavior that avoids the typical scaffold of empirical response functions. The premise is that canopy water demand is regulated in proportion to threat to supply posed by...
متن کاملPhotosynthetic and stomatal responses to high temperature and
quapin oak (Q. muehlenbergii Engl.) leaves were exposed to high temperatures at various photosynthetic photon flux densities under laboratory conditions to determine if species-specific responses to these factors were consistent with the distribution of these oaks in gallery forests in the tallgrass prairies of northeastern Kansas, USA. Measurements of the ratio of chlorophyll fluorescence decr...
متن کاملThe Role of ENHANCED RESPONSES TO ABA1 (ERA1) in Arabidopsis Stomatal Responses Is Beyond ABA Signaling.
Proper stomatal responses are essential for plant function in an altered environment. The core signaling pathway for abscisic acid (ABA)-induced stomatal closure involves perception of the hormone that leads to the activation of guard cell anion channels by the protein kinase OPEN STOMATA1. Several other regulators are suggested to modulate the ABA signaling pathway, including the protein ENHAN...
متن کاملComparison of cardiac output responses to 2,4-dinitrophenol-induced hypermetabolism and muscular work.
Both electrically induced exercise and infusion of 2,4-dinitrophenol (DNP) increased oxygen consumption and tissue metabolism in chloralose-anesthetized dogs. Cardiac output increased with oxygen consumption at the same rate in both experimental conditions. The increase in cardiac output induced by exercise was, as expected, accompanied by increases in both lactate-to-pyruvate ratio and "excess...
متن کاملCompanrson of Cardiac Output Responses to 2 , 4 - Dinitrophenol - Induced Hypermetabolism and Muscular Work
INTRODUCTION The principal factor initiating increased cardiac output during exercise, the "work stimulus," still is not fully understood (1). Both mechanical and metabolic factors have been identified with the "work stimulus." The former have been related to the stimulation of mechanical sensory receptors inside the muscles or tendons, and This work was presented in part at the Annual Meeting ...
