Armeniaca vulgaris, rootstocks, canopies, correlations.Abstract
The study presents the behaviour of 28 apricot cultivars planted in 2017 in the Experimental Field of the Faculty of Horticulture within the University of Agronomic Sciences and Veterinary Medicine of Bucharest. The foreign cultivars grafted on Myrobalan 29C, Saint Julien A and GF 677, were planted at 4.5 x 1.5 m and 3.5 x 2.0 m for Parallel U and respectively, 3.5 x 2.0 m for Trident canopy. Trees vegetative growth was evaluated by analysing the trunk cross section, tree height, fruiting branches number and length. First fruit yield was heighted and the productivity index was calculated. The results show differences in growth correlated with the canopy, cultivars and used rootstocks. Correlations between analysed parameters are presented. As a conclusion, the differences between the two canopies, Parallel U and Trident, using different types of rootstocks show their influence on the annual vegetative growth and on apricot trees productivity. Some preliminary conclusions can be drawn regarding the advantages and disadvantages of using the two canopies in apricot orchards.
