Морфологические показатели кустов голубики (Vaccinium corymbosum L.) в лесостепи Украины

Abstract

The authors present the outcomes of a two-year study on the growth peculiarities of the northern highbush blueberry (Vaccinium corymbosum L.) under the conditions of the Right-Bank Forest-Steppe of Ukraine (Kiev). The purpose of the research was to determine the biometric indices of blueberry plants (height, diameter and shape of the bush, the number and length of annual shoots and the assimilation surface area). Five varieties were studied: Amanda, Bluestar, Johnny, Kerry and Chick. These varieties were planted in the spring of 2008, according to the scheme 3 × 1 m. As a result of the performed investigations the varieties were divided into high- , moderately- and low-growing. The group of high-growing varieties included Amanda, Chick and Kerry varieties. Johnny variety was included in the group of moderately-growing and Bluestar variety was characterized by undersized bushes. Chick variety had a semi-spread bush shape while other varieties have an upright shape. The varieties Kerry and Chick developed more annual shoots, while Amanda and Kerry varieties have the longest ones. Chick and Kerry varieties are characterized by the greatest area of assimilation surface.
