The leaf is the primary photosynthetic organ of the plant. Photosynthesis is the process of absorbing energy from sunlight and using it to produce food in the form of sugars. Leaf hydraulic conductance (K leaf) varies widely among species (Brodribb et al., 2005; Sack and Holbrook, 2006; Sack and Scoffoni, 2013).Because the resistances inside and outside the leaf xylem (R ox) also vary widely and are, on average across species, of a similar order of magnitude (Sack and Holbrook, 2006), both vein traits and mesophyll anatomy have potentially strong influences on K leaf.
