Утолщение штамба и апикальный рост двупроводниковых саженцев яблони сорта флорина в зависимости от плотности размещения и способа создания двух проводников

Abstract. The research was carried out during the vegetation period of the year 2017 and it was aimed at studying 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 indicator 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 doublesided and alternate budding with two buds contribute to the increase of nursery plant height up to 139 cm
