The study presents the behaviour of 28 apricot cultivars planted in 2017 in theExperimental Field of the Faculty of Horticulture within the University of AgronomicSciences and Veterinary Medicine of Bucharest. The foreign cultivars grafted onMyrobalan 29C, Saint Julien A and GF 677, were planted at 4.5 x 1.5 m and 3.5 x 2.0 mfor Parallel U and respectively, 3.5 x 2.0 m for Trident canopy. Trees vegetativegrowth was evaluated by analysing the trunk cross section, tree height, fruitingbranches number and length. First fruit yield was heighted and the productivity indexwas calculated. The results show differences in growth correlated with the canopy,cultivars and used rootstocks. Correlations between analysed parameters arepresented. As a conclusion, the differences between the two canopies, Parallel U andTrident, using different types of rootstocks show their influence on the annualvegetative growth and on apricot trees productivity. Some preliminary conclusionscan be drawn regarding the advantages and disadvantages of using the two canopiesin apricot orchards.
