Plant response to atmospheric humidity
WebJan 7, 2013 · Abstract. Stomata are pores on the leaf surface, bounded by two guard cells, which control the uptake of CO (2) for photosynthesis and the concomitant loss of water vapor. In 1898, Francis Darwin showed that stomata close in response to reduced atmospheric relative humidity (rh); however, our understanding of the signaling pathway … WebFeb 17, 2024 · Along with its direct impact on plant physiology, high VPD results in increased rates of water loss from moist soils, in turn causing drying and heating of the terrestrial surfaces and contributing to more frequent and severe drought events and plant water stress (Dai, 2013 ).
