Abstract
Abstract The length of the lag phase following treatment and the persistence of the eventual growth suppression effect of 1.15 g paclobutrazol (PBZ) per tree declined as the area of treated soil surface beneath the tree increased. Treating one side of the tree row was as effective as treating both sides, but immediately adjacent “control” trees were largely unaffected by these soil-surface treatments. In a 2nd experiment, single, or multiple sprays applying the same amount of chemical in total gave equal growth control in the season of application, but residual growth control was slightly superior on trees sprayed four or 10 times. All PBZ treatments advanced anthesis but failed to improve flower number or fruit set. The weight of individual cherries was increased in each of the three years following the soil-surface application of PBZ, but, except for a reduction in soluble solids, fruit quality was unaffected. Foliar sprays of PBZ in 1984 led to larger fruit size in 1985, but fruit coloring was delayed and soluble solids were reduced. A preharvest spray of 20 ppm gibberellic acid (GA 3 ) substantially enhanced the PBZ effect on fruit size and color but also increased fruit firmness, juice acidity, stem length, and fruit removal force and reduced the incidence and severity of pitting following 2 weeks of cold storage. Chemical names used: β-[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1 H -1,2,4-triazole-1-ethanol (paclobutrazol).
