Abstract

A preliminary trial was carried out on sunlight interception and penetration into the canopy of different spacing-pruning configurations: "Central Spindle" (m 5.5 × 2), "Y Shape" (m 5.5 × 3) and "Standard Open Vase" (m 5.5 × 6). Sunlight distribution into the "Y Shape" tree canopy was 35% higher than the values measured in the "Central Spindle" canopy.
Mean light interception was similar in the three training systems with per cent values as follows: 74% in the "Y", 71% in the "Open Vase", 69% in the "Central Spindle".
