摘要：

Exogenous gibberellins GA(3) and GA(4+7) treatments on 'English Morello' sour cherry trees 58 days after an thesis were evaluated in relation to their effect on fruit firmness, size distribution, colour development, titratable acidity to firmness ratio, yield, efficiency indices as well as leaf fall senescence. Moreover in the season following the applications their effect on flower bud characteristics including frost hardiness, fruit set and fruit drop, were examined. Foliar GA(3) treatment had the most positive effect on 'English Morello' fruit size in the year of application and in the following season. GA(4+7) treatment in the first experimental year increased sour cherry fruit firmness. Both GA(3) and GA(4+7) delayed leaf senescence process in the autumn. GA(3) application had a positive effect on flower buds survival in comparison to control trees after frost occurred in spring. No GAs subsequent effect on next year fruit set and yield compared to control was found.
