Alternatives of chemical thinning in ‘Fuji Suprema’ apples
Abstract – The fruit thinning of an apple tree is one of the most important cultural practices for increasing fruit size and quality, in addition to avoiding the alternation of production.

| Sumario: | Abstract – The fruit thinning of an apple tree is one of the most important cultural practices for increasing fruit size and quality, in addition to avoiding the alternation of production. Chemical thinning is widely used in apple growing, because it reduces the need for labor and allows the activity to be performed in an appropriate period. Combinations of flowering and post-flowering chemical thinners have provided more effectve results for cultivars with high fruit set. The aim of this work was to evaluate the response of the application of combinations of flowering and post-flowering chemical thinners in ‘Fuji Suprema’ apple tree. The experiments were conducted from 2011 to 2013 evaluating the combination of benzyladenine (BA) with GA4+7+BA, ANA and ethephon, used in different concentrations and times of application. The flowering and post-flowering chemical thinners are efficient for ‘Fuji Suprema’ apple tree. The flowering chemical thinners GA4+7+BA or BA and the post-flowering chemical thinner BA combined with ANA or ethephon presented the closest results to hand thinning, being an efficient alternative. |
