In the conditions of the Republic of Belarus there were presented the results of the influence of manufacturing methods on a branching degree of annual seedlings of fruit crops in a nursery. It was revealed, that the method of an apical leaves nipping the most effectively stimulates branching at annual seedlings of apple and sweet cherry cultivars. The given method provides getting from 2 to 6 side shoots at apple yearlings and from 4 to 7 ones at sweet cherry (Prunus avium L.) trees. For a pear (Pyrus) tree the best variant is cutting on a crown which allows receiving 7 – 9 side shoots. Application of the growth regulators Circon and Regalis has appeared to be effective for branching stimulation at apple (Malus) and sweet cherry annual seedlings. It provides the formation of 5 – 10 side shoots of 12 – 15 cm in length depending on a cultivar. At seedlings treatment by Circon in concentration of 0,025 % and by Regalis in concentration of 0,3 % of the sweet cherry cultivar 'Gastsinets' there were developed 5 – 8 side shoots, while at a poor branching cultivar 'Gronkavaya' there were only 2 – 4 ones. For pear cultivars 'Lagodnaya' and 'Prosto Mariya' there was an effective application of the growth regulator Regalis in the concentration of 0,3 % that allowed plants to generate 3 side shoots of 13 – 15 cm in length.
