| Abstract:
Loads of 150,200 and 250 thousand buds/ha, obtained with 6-, 12- and 18-node long canes were compared, during two bearing years, in a factorial design on ‘Hayward’ kiwifruit. Percent bud break and fertile buds together with the number of fruit per flowering shoot proved unaffected by treatments, while the percentage of vegetative buds was higher in the shortest canes and at the lowest bud load. The shortest canes bore fewer fruit per bud. Plant yield increased according to bud load from 54 kg/vine (150 thousand buds/ha) up to 85 kg/vine (250 thousand buds/ha). As far as the pruning length is concerned vines in which 6-node long canes were left gave the lowest yield. No interaction between pruning length and bud load was found. Fasciated fruit occurred more frequently in the last 2–3 buds of the cane regardless of its length or the bud load of the vine. | |
