Abstract
This study was carried out on one-year old sweet cherry trees of ‘Burlat’, ‘Canada Giant’, ‘Hedelfinger’, ‘Summer Sun’ and ‘Sunburst’ grafted on both ‘Colt’ and ‘Gisela 6’ in order to determine their compatibility. For this purpose, peroxidase (PRX) isoenzyme bands were identified by polyacrylamide gel electrophoresis (PAGE). Samples of inner bark were taken 12 months after grafting from the following three zones: rootstock, grafting union (which included 5 cm above and below grafting union) and central part of the scion. ‘Hybrid’ zymogram of PRX from grafting union having all bands from both graft partners might indicate compatible grafting combination between ‘Summer Sun’ and ‘Colt’. In all the other cultivar/rootstock combinations, some symptoms of incompatibility can be expected. The results showed that peroxidase activity could be used as a parameter in the early determination of possible graft incompatibility in sweet cherry.
Istraživanja su sprovedena na jednogodišnjim sadnicama trešnje sorti Burlat, Canada Giant, Hedelfinger, Summer Sun i Sunburst, kalemljenih na podloge Colt i Gisela 6. Cilj istraživanja je bio da se utvrdi kompatibilnost ispitivanih kombinacija sorta/podloga. Kompatibilnost je utvrđena na osnovu peroksidazne (PRX) aktivnosti, za čiju je analizu korišćen metod poliakrilamidne gel elektroforeze (PAGE). Uzorci unutrašnje kore su uzeti 12 meseci posle kalemljenja, iz sledeće tri zone: podloga, spojno mesto (dužine 5 cm iznad i 5 cm ispod spojnog mesta) i sorta. “Hibridni” PRX zimogram dobijen analizom spojnog mesta, koji je sadržao sve trake sorte Summer Sun i podloge Colt, ukazuje na kompatibilnost ove kombinacije. U svim ostalim kombinacijama sorta/podloga mogu se očekivati neki od simptoma inkompatibilnosti. Rezultati ukazuju da se peroksidazna aktivnost može koristiti kao parametar za utvrđivanje pozne inkompatibilnosti sorti trešnje na vegetativnim podlogama koje su dobijene međuvrsnom... hibridizacijom.
