Ten farm experiments were made in 1987 and 1988 with five apple cultivars. Bee pollination was limited by caging branches during shorter or longer time in the blossoming period. Intensity of bee visits was observed and yield was measured. Reduction of the effective period of bee pollination dramatically reduced the yield. Intensity and/or limitation of bee pollination has not been proved to be of significant effect on fruit quality. At the same time, it has been established that the widely accepted dogma "the more the number of fruits the smaller the size and the mass of apples" has not been fully valid at the branch level under the conditions of bee pollination, because no effect was found on the size of apples when there was at least an acceptable yield (10 or more apples per 200 flower) on branches receiving intensive bee visits of different duration in cvs. Idared, Jonee, and Starkrimson Delicious
