Plum is a specie cultivated from ancient times, and the hilly area in the south of the country show suitability for this culture especially for the plantations with valuable varieties and rootstocks. The work shows the influence of the variety, rootstock and the combination variety/rootstock on growth issues, correlations between genetic and physiological processes that occur. The data obtained emphasize the rootstock underground part, his influence on the growth of the trees and phenophases addressing all components. The varieties of plum tree investigated have presented a good compatibility with the two rootstocks, ('Oteșani 8’ and 'P.F. Roșior văratic’). The plum varieties grafted on 'Oteșani 8’ rootstock showed a higher intensity of photosynthesis and 'Oteșani 8’ rootstock influenced more the chlorophyll ratio a/b.'P.F. Roșior văratic’ rootstock influenced the content of carotenoid pigments. The right choice of the combination variety/rootstock with the performance of the correct production technologies, can ensure high yields and quality of fruits.
