| Abstract:
In this work 5 rootstocks (apricot seedling, Nemaguard, GF-31, Pixy, a plumcot) and 7 cultivars (as dried apricot cvs: Hacihaliloglu, Kabaasi, as table apricot cvs: Karacabey, Aprikoz, Beliana, Rouge du Roussillon, J.Foulon) were used. The rates of bud-takes of all experimental cvs were low on Pixy rootstocks. From the stand point of stem diameters and heights it was found that apricot seedlings and plumcot's rooted cuttings were the strongest, GF-31's rooted cuttings were strong and Nemaguard and Pixy seedlings were weak rootstocks. Among the cvs, Kabaasi seemed to be weaker than the others. Branching of the nursery plants was less on Pixy than the other rootstocks. The uptakes of N, P, Ca and Mg were affected by the rootstocks. In the leaves of the cvs budded on different rootstocks the levels of N and P were found normal but the K levels were generally very high due to the high K contents of the soils. The leaves were found deficient in Ca and Mg because of the antagonistic effect of K, Fe, Mn, Zn and Cu contents of the leaves were found adequate and it seemed that their uptakes with the exception of that of Fe, were not affected by the rootstocks. | |
