Branches of 15-year-old grafts representing three clones underwent girdling. A varying influence of girdling on fructification was observed. Increase in endogenous gibberellin content in embryonic shoots 48 hours after treatment was most distinct in the less polar gibberellins at levels Rf 0.4-0.6 and 0.8-1.0. Clones were found to exert a stronger influence on endogenous auxins content than girdling.
