Abstract

Specific leaf weight (SLW), net photosynthesis (Pn), and dark respiration (Rd) of apple leaves were monitored for an entire growing season. Leaves were sampled from the canopy interior and periphery to provide a range of SLW. Leaf Pnwas linearly correlated with SLW until mid-August, when Pnbegan to decline. During September the relationship between SLW and Pnwas a quadratic. Leaf Rdand SLW were linearly correlated throughout the season. Leaf Pnand Rdwere significantly correlated through most of the season, but the relationship was not always linear. Specific leaf weight appears to be a reliable index of the previous light environment of a leaf, but use to estimate Pnis probably limited to the first half of the season, because of increased variation after mid-August.
