Photosynthesis and growth in diverse willow genotypes

During a study of the contribution of photosynthetic traits to biomass yield among 11 diverse species of willow, the light and CO 2 dependence of photosynthesis were found to differ, with absolute rates at ambient and saturating CO 2 , together with maximum rates of Rubsico-limited and electron-transportlimited photosynthesis ( V cmax and J , respectively) varying by factors in excess of 2…
