Relationship between NPQ and qPd (open circles) and NPQ and photosystem II effective quantum yield (closed circles) determined in 1-, 7-, and 13-week-old leaves of Prunus cerasifera clone 29C (A,C,E, respectively) and Prunus cerasifera var. Pissardii (B,D,F, respectively). Data are means of at least 12 replicates of intact leaves; error bars represent the standard error. Theoretical quantum yield (continuous line) was calculated using the Equation (1) reported I Materials and Methods section with qPd = 1.
