Abstract
In this experiment, early ripening plum trees were pruned at two different times. The experiment was conducted at the Fruit Experimental Station in Samotwor near Wroclaw in 2001-2004. Objects of the study were 8 year-old plum trees of 'Herman', 'Cacanska Rana', 'Sanctus Hubertus' and 'Cacanska Lepotica' cultivars budded on 'Myrobalan' seedlings (Prunus divaricata). The experiment was established in a randomised block design in three replications with 6 trees per plot. In 2001-2003, time of tree pruning was differentiated. Half of the trees were pruned only at the end of August (summer pruning after harvest of fruit). The other pruning took place at the end of March (dormant pruning before blooming time). Time of pruning had no influence on vegetative growth and chemical composition of leaves. No matter what the time of pruning, the total sugars, reducing sugars, potassium, calcium, magnesium and phosphorus contents in leaves were similar. Sugars, calcium and phosphorus contents were significantly influenced by the year. Foliar nutrient content differed according to the plum cultivar. 'Sanctus Hubertus' showed markedly lower leaf K and Mg contents, whereas 'Cacanska Lepotica' had a higher P content. Pruning time had an influence on the crop efficiency index. Dormant-pruned trees were significantly more productive.
