Abstract

The aim of our study was to compare the growth vigour of three plum cultivars grafted onto four different rootstocks. The vegetative characteristics of rootstock-scion combinations can determine, along with other factors, planting density. Informed decisions regarding tree spacing are needed in commercial orchards to increase profitability, and the use of rootstocks which induce a weaker vigour in cultivars can allow for intensive orchard management. We measured trunk cross-sectional area (TCSA), total volume of shoot growth and canopy volume. The trees were planted in a low nutrient content, sandy soil. Based on the first two years of results ‘St Julien A’ proved to dwarfing, while ‘Marianna 2624’ exceled in its adaptability and drought resistance compared to myrobalan rootstocks in these conditions.
