ASPECTS REGARDING THE BEHAVIOUR OF THE INTERACTION VARIETY/ROOTSTOCK AT SOME TREE VARIETIES ON THE SOILS FROM THE REGION OF OLTENIA

Abstract

The root growth, the time of growth and the exerted functions are important aspects that we should consider. One of these important functions is the settlement into the ground which is achieved by the rootstock, by distributing horizontally and vertically, but also by their density.
The apricot varieties on the Armeniaca vulgaris rootstock had different growths and the Umberto and Neptun apricot varieties had weaker vigour. The affinity between the apricot varieties and the Armeniaca vulgaris varieties was very good (0,98-0,99).
The Bella di Giugno pear variety was more superficially anchored in sand and the Williams, Red Williams and Republica varieties had a deep root system, according to the research method. Great vigour was observed at the Napoca, Williams and Red Williams varieties and the compatibility of the pear varieties on Armeniaca vulgaris was very good. The apricot and pear varieties observed on those rootstocks can also be extended to other areas.
