Abstract
The seasonal effect of fruiting and environmental impacts on leaf and whole-canopy carbon dioxide exchange was examined using mature six-year-old ‘Braeburn’/M.26 apple trees.
Crop load affected leaf- and whole-canopy net CO2 uptake.
Differences in average canopy net CO2 exchange were partly explained by average canopy light interception and night-time air temperature.
Mid-season decline in photosynthesis was associated with an increase in leaf starch concentration as crop load decreased, presumably due to a lower carbohydrate requirement at this growth period.
