WebIntroduction. Leaf hydraulic conductance (K leaf), which refers to the efficiency of liquid water transport through the leaf, is an important constraint on photosynthesis rates (Scoffoni et al., 2024).Light intensity has been shown to affect K leaf and the photosynthetic performance of leaves. For instance, upper canopy leaves have higher K leaf and less leaf hydraulic … Xenon short-arc lamps come in two distinct varieties: pure xenon, which contains only xenon gas; and xenon-mercury, which contains xenon gas and a small amount of mercury metal. In a pure xenon lamp, the majority of the light is generated within a tiny, pinpoint-sized cloud of plasma situated where the electron stream leaves the …
