AB  - In this paper the results of chemical fruit thinning in the apple cultivar ‘Granny Smith’ carried out with the herbicide Brevis® containing 150 g kg-1 of metamitron as the active ingredient are reported. In two treatments, the effect of this compound was enhanced by NAA (1-naphthaleneacetic acid). This study was conducted in a commercial apple orchard of PIK “Južni Banat” located in Bela Crkva (Serbia), in two consecutive years (2013, 2014). The planting distance was 3.3×0.8 m (3878 trees ha-1) and trees were trained as slender spindle. Brevis® was sprayed when central fruits in the clusters were 12-14 mm in diameter. Applied treatments in ‘Granny Smith’ were as follows: control, 150, 188, 225, 150 mg L-1 of metamitron + 5 mg L-1 NAA and 225 mg L-1 metamitron + 5 mg L-1 NAA. Spraying volume was 800 L ha-1 in all applied treatments. Metamitron expressed a positive influence on crop load in both investigated years. Treatments containing metamitron alone provided large yield consisting of a high percentage of first quality fruit. The effect of metamitron could be enhanced by mixing with NAA.

AB  - In the present study, the influence of different agents for apple tree chemical thinning on yield components and fruit quality was investigated. The experiment was conducted in apple orchard established with cultivars 'Idared', 'Golden Delicious' and 'Mondial Gala' during 2009. The agents tested were Napthalenacetamid (NAD), alpha-naphtaleneacetic acid (NAA, two concentrations) and Carbaryl (Sevin WP-50). Chemical thinning expressed significant influence on decreasing of fruit number per tree and increasing of fruit size. Among the tested agents only Carbaryl did not show these effects in 'Golden Delicious'. Yield per tree was not affected by chemical treatments in 'Idared', whereas the thinning significantly decreased the yields in 'Golden Delicious' and 'Mondial Gala'. A significant return bloom was recorded in all chemical treatments in 'Idared' and 'Golden Delicious'. Chemical fruit composition was not influenced by thinning treatments in all tested cultivars. In 'Mondial Gala' more intensive fruit colour was recorded in the treatments with Carbaryl and NAD, which also reduced the fruit number per tree.
