Abstract
The aim of carried out research was comparing the effect of different pruning time on cropping and fruit quality of several early ripening plum cultivars. The experiment was conducted at Fruit Experimental Station – Samotwór near Wrocław in 2001–2004. Objects of studies consisted of 8 year-old plum trees of ‘Herman’, ‘Čačanska Rana’, ‘Sanctus Hubertus’ and ‘Čačanska Lepotica’ cultivars budded on ‘Myrobalan’ seedlings (Prunus divaricata). The experiment was established in a randomised block design in three replications with six trees per plot. In 2001–2003, time of tree pruning was differentiated. Half of trees was pruned only at the end of August (summer pruning after harvest of fruit) and the other one only at the end of March (dormant pruning before blooming time). Time of pruning had no influence on yielding and chemical composition of fruit. Soluble solids, vitamin C, magnesium, calcium, potassium and phosphorus contents in fruit were similar independently of pruning time. Mean fruit weight was significantly higher from trees with dormant pruning.
