INFLUENCE OF ROOTSTOCK ON THE GROWTH AND FRUCTIFICATION OF PEAR VARIETIES IN OLTENIA
Pear extension is a necessity for our country. There are many areas favourable for the pear species in the country, and the Oltenia area has proved to be an area with particularly favourable climatic conditions for varieties and rootstocks. Depth of rooting, as well as branching, is a genetic feature of the variety and species. Within the experience, there are varieties with a highly developed radicular system (absorbent roots helping to absorb the fertilizer better) and such varieties with roots that reach 80 cm are Untoasă Giffard, Untoasă Hardy, Abatele Fetel and Cure. The period of growth of pear varieties ranged from 56 to 67 days. The varieties showed a good affinity of the two partners, namely a growing behaviour and very good development of the partners. Physical and chemical properties help us to orient the respective varieties for fresh direct consumption as well as for industrial processing in different forms. From the researched type there can be kept in the culture for the southern area of Oltenia the varieties: Untoasă Hardy, Passe Crassane, Olivier de Serres and Cure.
