Abstract
Spatial heterogeneity of radiation incidence and interception for canopies of kiwifruit (Actinidia deliciosa) vines was considered in terms of trellis design, canopy shape, leaf area distribution, and incident radiation at different depths within the canopy. Incident radiation was uniform across the surface of a canopy trained on a horizontal “Pergola” trellis, but was frequently reduced at distal regions of the canopy surface for a vine trained on a “T-bar” trellis with faces inclined downwards, due to partial or complete shading. Leaf area index also tended to decline with distance from the central cordon, further reducing radiation interception in these zones. Compared to radiation levels above the canopy, incident radiation at any position within the canopy varied diurnally according to the leaf area between the sensor and the radiation source (which in turn was affected by the shape of the canopy trellis and by canopy growth during the season) and the fraction of total radiation that was diffuse. Spatial heterogeneity of radiation incidence and interception can be linked to heterogeneity of fruit growth and quality.
