STUDIES ON THE DEVELOPMENT OF SOME STRATEGIES FOR SWEET CHERRY TREE PLANTING DISTANCE AND MANAGEMENT

This papers presents the growth and fruiting of the Valerii Chkalov, Record, Ferrovia, Kordia, Regina, Stella, Skeena, Bigarreau Burlat, Lapins, Early Star, Samba and Black Star varieties, grafted on the Cerasus mahaleb, L., MaxMa 14 and Gisela-6 rootstocks in different combinations and planted at different distances, which are grown in the southern and central area of the Republic of Moldova have been investigated. The sweet cherry trees with an age between 9 to 14 years that had been grafted on Cerasus mahaleb, L. showed a stronger growth as compared to the trees with an age between 4 to 10 years that had been grafted on Gisela 6, and the tees with an age between 8 to 10 years which had been grafted on MaxMa 14. High vigour trees are grown on non-irrigated soils; the sweet cherry trees, grafted on Gisela 6 and MaxMa 14 rootstocks are grown on fertile well-irrigated soils. The studied associations of varieties and rootstocks turned out to be suitable for cultivation in terms of the soil and climatic conditions of the area.
