| Abstract:
Shoots borne in the replacement zone of kiwifruit vines growing on a ‘T-bar’ trellis system were monitored from initiation in Year 1 to commercial fruit harvest in Year 2. Vegetative, flowering and fruit quality characteristics of these shoots were measured. Cane size was a major factor influencing flower production and fruit quality. Longer canes had greater winter bud number per cane and/or higher bud burst than shorter canes. Flower number and fruit yield per cane were greater for longer canes. However yield/m cane was not influenced by cane size. Fruit size at harvest was also higher on the larger canes. Within canes, fruit were heaviest near the base of the cane. A significant proportion of the variation in fruit size among four cane types was related to the variation in seed dry weight per fruit. | |
