Influence of the rootstock on the physical-mechanical properties of the plum fruit (Prunus domestica L.)

Abstract

The research was conducted in the experimental-production plum orchard during 2013. Some of the most important physical and mechanical properties of the fruit were investigated in three plum cultivars ("Čačanska Rana", "Čačanska Lepotica" i "Čačanska Najbolja") grafted on four rootstocks: one generative Myrobalan (Prunus cerasifera Ehrh.) and three vegetative ones (Pixy, St. Julien A and Ferley). St. Julien A induced the highest all three fruit dimensions in "Čačanska Najbolja", and length and thickness in "Čačanska Lepotica". Myrobalan and Fereley had the same effect in the "Čačanska Rana". St. Julien A influenced the biggest fruit firmness in "Čačanska Najbolja" and the smallest in "Čačanska Lepotica".
