Abstract

SummaryLarge increases in fruit size and yield of Victoria plum were obtained when mixtures of GA3 and an auxin were applied four and six weeks after petal fall, whether or not D PU was included in the mixtures. GA3 was essential in the first spray and beneficial in the second. Of the three auxins tested, 2,4,5-TP was more effective than NOXA, and, compared with NAA, did not reduce fruit size in the year of application or flowering in the following year. Hand thinning fruitlets two weeks after applying hormone sprays increased the size of the remaining fruits and the fruit bud production of the sprayed trees. The application of PP528 to sprayed trees, although reducing yield, failed to improve fruit weight and did not greatly alleviate the reduction in return bloom.
