The maximum quantum efficiency of CO2 assimilation declines with depth in the canopies of the C4 crops Miscanthus x giganteus and Zea mays
… were taken on healthy upper and lower canopy leaves of M. x giganteus and Z. mays, and isolated aging leaves of M. x giganteus. The maximum quantum yield of CO2 assimilation (ΦCO2, max) was derived from the initial linear slope of the responses of leaf CO2 uptake (A) to photon flux (Q) …

Hydrolytic enzyme activities in leaf senescense
… that in excised apical portions of wheat leaves kept in the light acid phosphatase activity slowly increases with time. Contrary to this interpretation, however, dark incubation of excised leaf tips diminishes the acid phosphatase response, although it accelerates chlorophyll loss. Acid …
