Abstract
Paclobutrazol applied as a collar drench at the end of June to young trees of peach cv.
Hakuho on seedling rootstocks caused a significant reduction in growth in the second year, but in the third year the treated trees tended to grow more than the controls.
However, by repeating the treatment each year it was possible to maintain tree size at a desirable level.
Although yield per tree was reduced, the weight of fruit harvested per m3 of canopy or per unit of trunk cross-sectional area was increased.

In sweet cherry cv.
Satonishiki on seedling rootstocks paclobutrazol as a soil drench or a foliar spray resulted in many more floral buds per m3 of tree crown and increased the yield per tree.
Apart from a slight shortening of the peduncle, which did not affect marketability, there were no significant differences in fruit quality.
