Abstract

Modern training and production systems of plum allow a more efficient production. The aim of this experiment was to optimize the crop load and fruit quality of some new plum cultivars (‘Cacac beauty’ and ‘Hanita’) by using chemical fruit thinning (ATS, Armothin and Etephon- Amid). Amonium-thio-sulphate (ATS) can be recommended for fruit thinning of plum cultivars ‘Cacac beauty’ and ‘Hanita’ in the full bloom. The concentration of 1%, 5% ATS has proved to be enough good according to strongly improvement of fruit quality and reducing of crop load. Armothine, applied in the full bloom can be used for thinning of the examined plum cultivars. As a good concentration could be recommended concentration of 1 and 5 % according fruit quality and affecting the fruit dropping. It was observed a significant better improvement of fruit quality in the cultivar ‘Hanita’ than in ‘Cacac beauty’ cultivar. Ethephon-Amid, compared to ATS and Armothin appeared to be worse thinner for the examined cultivars. A special attention should be paid to the concentration and sensibility of cultivars. The concentration of 120 ppm caused to intensive fruit dropping of the ‘Cacac beauty’ cultivar.
