Abstract:
G A 3 sprays (50, 65, 100 mg/L) were applied to six single tree replications of mature `Redhaven' and `Cresthaven' trees on 23 June 1989 to measure their effect on fruit maturity and the relationship among its indices. There was little effect of GA 3 on fruit diameter except on the final harvest when the treated trees had 6% larger fruits. Seventy-two percent of the total yield of `Redhaven' control trees was mature at the first picking while only 30% of total yield from treated trees was ready on the same date. GA 3 had a similar effect on fruit maturation on `Cresthaven'. Fruit on treated `Redhaven' trees were on average 1.3 kg firmer than control. Furthermore, GA 3 increased the firmness over control on the shaded and sunny side and the suture of the fruit and no interaction between the location of pressure test and GA 3 treatments was observed. There was a slight reduction in yellow ground color of G A 3 treated fruits. The effect of GA 3 on the relationship between individual fruit color and firmness will be examined. The effects of 1990 GA 3 sprays on peach maturity and quality will also be presented.
