The research was carried out during the vegetation period of the year 2017 and it was aimed at stu-dying the growth processes in bi-axis nursery apple-trees of Florina cultivar on 54-118 rootstock, depending on planting density and the way of forming two axes. It has been established that the cultivation of bi-axis nursery trees by means of double-sided and alternate budding with two buds enables to increase the trunk diameter indica-tor up to 16.5 and 16.7 mm. The increase of the inter-row spacing up to 65 cm facilitates the thickening of the trunk of bi-axis nursery apple-trees by 1.7 mm as compared with the traditional spacing – 33 cm (15.1 mm). The nursery trees grown in a 45-cm inter-row spacing had the largest height, namely 140 cm. Also it was found out that double-sided and alternate budding with two buds contribute to the increase of nursery plant height up to 139 cm.
