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 … WebJun 1, 2010 · Briskin and Gawienowski (2001) reported that growing St. John's wort plants at a PPF of 400 μmol·m −2 ·s −1 significantly increased the hypericin concentration with enhanced photosynthetic activity. Light is also involved in regulating antioxidant enzymes and secondary metabolites.
