In the conditions of the Republic of Belarus within 2005-2012 (concerning two age periods of a fruit tree life) there were carried out the researches on the study of the influence of cherry (Prunus cerasus L.) crown shapes on trees growth and fruit bearing. It was made with the aim to estimate and select the optimal crown shape taking into account some peculiarities of the experienced cultivars such as 'Vyanok', 'Griot Byelorusski' and 'Zaranka' on a seed rootstock of the cerasiis avium, which allows receiving high yields of fruits. A naturally improved crown shape is the most optimal for the cultivars studied in the experience. It is characterized by smaller indexes of a vegetative tree growth, i.e. the area and increment of a cross sectional area of a stem. It was reached at the expense of smaller quantity of boughs in a crown skeleton. Total productivity at the given crown shape for the research years made 20,8 tons per hectare at the cultivar 'Vyanok', 11,9 tons per hectare at the cultivar 'Griot Byelorusski' and 6,5 tons per hectare at the cultivar 'Zaranka'.
