Abstract
Abstract Boysenberry (Rubus hybrid) plants were sprayed to run-off with 4-chlorophenoxyacetic acid (4-CPA) at 100 mg litre-1, in the 1983–84 season, when 80% of flowers had reached anthesis. Harvested yield was not affected by 4-CPA treatment. Berry size was significantly increased because of greater numbers of drupelets in the berries. Drupelet numbers were always increased by 4-CPA, irrespective of the level of insect pollination. Fruit from plants sprayed with 4-CPA ripened one week later than fruit from unsprayed plants, but length of harvest period remained unaltered.
