The plum varieties Edinburgskaya, Mirnaya, Dalikatnaya, Kroman, Narach, Venera, Charadziejka of the Belarasian and Russian selection on the cherryplum rootstock at the experimental orchard planted in 1998 (scheme of planting 5 x 3 m) were studied. It was established that during the period of full fruiting the studied varieties had quite sharp distinctions in crown shape despite annual training and pruning but their parameters did not exceed the parameters of orbicular shape. Studying of arrangement of floral and shoot buds on annual shoots of different diameter and located in various parts of a crone of a tree has shown that more quantity of floral buds is laid on the shoots of continuation of higher orders of branching located more horizontally and having average diameter. The structure of crown had 4 distinct orders of branching. The vigorous variety Dalikatnaya has formed branches of the 5th order up to 8%. The majority of branches of the weak-grown variety Charadziejka had the 2nd order of branching whereas the number of the 4th order branches has made 2% only. Most of bouquet branches of all varieties were 3-4 years old. Bouquet branches of winter-hardy varieties Dalikatnaya, Mirnaya, Narach older than 4 years amounted to 40%. One-year-old sprouts had a certain fruit load and more flower buds are formed in the central part on sprouts of more higher branches orders and are placed more horizontally
