The study was conducted in two successive years to examine the capacity of formation of sylleptic shoots in nursery trees of ‘Abbé Fétel’, ‘Conference’ and ‘Starking Delicious’ pear cultivars grafted on quince MA and quince BA 29 rootstocks during the first year after bud grafting. Tree height, trunk diameter – 10 cm above the bud union and number of sylleptic shoots were measured at the end of each season. Tree height was measured from the ground level. The greatest number of sylleptic shoots was registered in ‘Abbé Fétel’ in both seasons, and the smallest in ‘Starking Delicious’. Tree height and tree diameter were highly significantly affected by cultivar in both years and by rootstock in 2008. The interactions between them did not significantly affect the examined parameters. The study showed that the early growth and syllepsis of pear nursery trees during the first year after bud-grafting were incomparably more affected by cultivar than by rootstock.

Badanie przeprowadzono w dwóch kolejnych latach w celu zbadania zdolności tworzenia pędów syleptycznych u drzewek gruszy odmian ‘Abbé Fétel’, ‘Conference’ oraz ‘Starking Delicious’ okulizowanych na podkładkach pigwy MA oraz BA 29 w pierwszym roku wzrostu okulantów. W każdym sezonie mierzono wysokość drzewa, średnicę pnia na wysokości 10 cm nad miejscem okulizacji, a także liczbę pędów syleptycznych. Wysokość drzewa mierzono od poziomu gruntu. Najwyższą liczbę pędów syleptycznych zanotowano w obu sezonach dla ‘Abbé Fétel’, natomiast najmniejszą dla ‘Starking Delicious’. Na wysokość i średnicę drzewa istotny wpływa miała w obu latach odmiana, a w roku 2008 – podkładka. Współzależność między komponentami nie wpłynęła w sposób istotny na badane parametry. Badania wykazały, że na wzrost oraz rozgałęzianie się drzew gruszy podczas pierwszego roku po okulizacji większy wpływ miała odmiana niż podkładka.
