Abstract

Plum is a rustic species that succeeds in minimal agrotechnic conditions and therefore has expanded extensively in the gardens of the population. Particularly favorable ecological conditions for the plum culture allow for the expansion of new varieties, recently created in our country or imported from abroad. By properly applying crop technologies, high and consistent production can be achieved to meet the needs of domestic consumption and to ensure availability for export. The researches were carried out between 2014 and 2016 within a plantation set up in 1995. The biological material used in this paper is represented by 19 plum varieties (Diana, Ialomiţa, Silvia, Piteştean, Centenar, Minerva, Flora, Carpatin, Valcea, Tita, Tuleugras, RenclodAlthan, Pescăruş, Dâmboviţa, Record and Anna Spath) grafted on 3 or 4 rootstocks (Oteşani 8, Pixy, Miroval and Roşiorvăratic). The paper aims to establish the rootstock's influence on growth and fructification within the graft / rootstock biosystem. The Oteşani 8 rootstock imprints to the studied varieties the smallest growth, while the Miroval rootstock imprints the highest growth force to the varieties studied. In all studied elements. Pixy and Roşiorvăratic varieties give to the studied varieties an average growth force compared to the other two rootstocks.
