Rezumat

The study subject of the experience was Fuji Kiku apple variety, grafted on M9. The trees were trained as slender spindle training system. The distance of plantation is 3.5 x 0.8 m. The experimental plot it was placed in the orchard „Domulterra” Ltd. founded in 2013 year. The research was conducted during the period of 2016 year. This study had the aim to determine the efficacy of different agents on the thin-ning of apple fruits. To study thinning of apple fruits were experimented the following variants: 1. Control – without treatment; 2. Manual thinning; 3. Ger ATS LG, 12 l/ha; 4. Geramid New, 1,5 l/ha; 5. Dirager, 0,3 l/ha; 6. Goltex 700SC, 3,5 l/ha; 7. Dira Max LG, 2,5 l/ha; 8. Gerba 4 LG, 2,5 l/ha. During the research, it was studied the number of blossom clusters after thinning, mean fruit weight, yield, average fruit diameter and size classes based on their diameter. It was established that, the good effect of thinning was noticed after two application of Ger ATS LG, 12 l/ha. In the case of no favorable conditions during the previous treatment, it is possible to utilize Goltex 700SC, 3.5 l / ha, Dira Max LG, 2.50 l/ha and Gerba 4 LG in the dose 2.5 l / ha, when the size of the central flower of the inflorescence has a diameter of 10-15 mm. It not recommended for the Fuji Kiku variety to use growth regulators based on NAD (Geramid New) and ANA (Dirager), because formed a large pygmy fruits.
