CYANIMIDE IMPROVES CROPPING PERFORMANCE OF KIWIFRUIT VARIETY HAYWARD IN WESTERN AUSTRALIA
DormexR was applied at 2, 4 and 6 weeks before anticipated bud burst and at three rates, namely 1.0, 2.5 and 5.0 percent. Recordings of bud burst, flowering and fruit set indicate that best results are obtained with 5 percent DormexR applied 4 weeks prior to anticipated bud burst. Whilst the better treatments doubled the number of buds that burst, they had an even greater effect on the level of flowering and fruit set. Other effects of DormexR were to approximately halve the spread of flowering, as well as to promote earlier, more uniform bud break.
DormexR has the potential to enable reliable crops of the Hayward variety to be obtained under Western Australian conditions. These experiments showed that crop levels expressed as fruit per dormant winter bud, increased from 0.2 to 1.2 in a mild winter, and from 1.2 to 1.9 in a cooler season.
