Post-bloom thinning with 6-benzyladenine improves apple fruit quality
The effect of the post-bloom thinning agent 6-benzyladenine (BA) on fruit quality was examined on both ‘Delicious’ and ‘Golden Delicious’ apple cultivars over a two-year period in Tasmania. A standard program of bloom thinners was used in all trials prior to application of BA. Seed numbers were reduced markedly in ‘Delicious’ but only slightly in ‘Golden Delicious’. Fruit increased in firmness and soluble solids concentration in both cultivars with BA treatment. Pygmy fruit were produced by some treatments in one of the ‘Delicious’ trials. BA counteracted the fruit flattening effect of ethephon in the first year ‘Delicious’ trial but not in the second; BA had no effect on fruit shape of ‘Golden Delicious’. Overall, BA had a positive effect on fruit quality in the two apple cultivars studied. This study provides further evidence that both temperature and application time play an important role in the effectiveness of BA as a post-bloom thinner and its impact on fruit quality.
