FRUIT QUALITY IN FUNCTION OF THE GRAFT/ROOTSTOCK BIOSYSTEM WITH SOME PLUM TREE VARIETIES
The paper emphasizes the fruit quality with different plum tree varieties in functionÂ of the graft/rootstock biosystem in an orchard located eastward of Craiova town.
The researches have been carried out in 2006-2008 period and there were studiedÂ 7 plum tree varieties (IALOMIŢA, FLORA, VÃ‚LCEAN, TULEU GRAS, DÃ‚MBOVIŢA,Â VALOR and STANLEY) which were grafted on 4 rootstocks (Oteşani 8, Pixy, Miroval andÂ Roşior văratic).
Â The main researched aspects on fruit have been: the size and the mass of the fruit,Â the mass of the kernel, the pulp and kernel ratio, the number of fruits and kernels per kg asÂ well as the content of soluble dry matter and sugar of the fruits.
After the study, the Vâlcean variety recorded the fruits with the biggest size (49.34Â mm) and mass (71.58 g), for one kg of fruits there was needed 14 units. AnotherÂ conclusion is that Stanley variety has recorded the highest percent of soluble dry matterÂ (23.10%).
