Short summary
The aim of this study was to quantify the water requirements of young and mature unstressed apple orchards. We also assess the impact of climate variables on transpiration rates. For mature trees, ‘Cripps’ Pink’ trees tend to use less water than ‘Golden Delicious’. This is because they tend to have more open canopies due to management practices. Transpiration was linearly related to the solar radiation, while the relationship between transpiration and VPD was non-linear.
