e1“Panicum maximum Jacq. using a temperature‐free air‐controlled enhancement (T‐FACE) system. The wS and eT treatments showed no effects on photosystem II photochemistry. However, wS under ambient temperature decreased net photosynthesis rate ( A ), stomatal conductance ( g s ) and maximum rate of carboxylation of Rubisco ( V cmax ), leading to a reduced starch content in leaves. A 16% reduction in leaf dry mass (LDM) a…” Show full quote
