Sažetak
In fruit production thinning is very important to achieved production with optimal fruit number per tree of high quality. Thinning of plum fruit is mostly still done by hand which is costly and not an economically viable. In this experiment, the mechanical string thinner, Darwin, was used for thinning of plum trees. Mechanical blossom thinning with Darwin is a new thinning option for plum production. The objective of this study was to evaluate the influence of mechanical thinning at bloom on plum yield and fruit quality. The trial was performed at the Agricultural institute Osijek, on experimental orchard Tovljač during the 2017 season, on the cultivars Stanley and Čačanska ljepotica. In trail hand-thinned control was used for compared to mechanical thinning performed with the Darwin. Results showed that mechanical thinning with Darwin decreased the total yield per tree in both cultivars compared to the control. Average fruit weight increased with increasing in rotor speed. Fruit firmness and TST in treatment with mechanical thinning also increased in both cultivars compared to control. This study provides preliminary data about mechanical blossom thinning of plum and it demonstrated that mechanical bloosom thinning have potential in plum production as alternative to hand thinning.
