Sažetak
The effect of 10 ppm 3, 5, 6-TPA (3, 5, 6-trichloro-2-pyridyloxyocetic acid) , 20 ppm GA 3 and their combination on size and weight of cherry fruit (Prunus avium L. cv. Regina) were studied. 3, 5, 6-TPA was applied 25 days after full bloom and GA 3 during stage of fruit color change from green to straw-yellow. Fruit height, width, thickness and weight were measured. Width, thickness and weight of control fruit were the smallest. Fruit from 3, 5, 6-TPA - treated trees did not show significant difference in comparison to control. However, fruit from GA 3 – treated trees had significantly improved all characteristics in comparison to control fruits. Weight of fruit from trees treated with combination of 3, 5, 6-TPA and GA 3 was 14 % higher than control fruit and 2, 8 % higher than fruit from GA 3 - treated trees, but there were no significant difference comparing to fruit from trees treated with GA 3 alone. These results are preliminary results after a one-year study and more research should be done to examine the possible influence of other factors, such as ecological factors, before final management recommendations could be made.
