MICROCLONAL PROPAGATION OF THE VARIETIES OF HIGHBUSH BLUEBERRY Vaccinium corymbosum L.

Abstract

The aim of the work was to determine optimal conditions for clonal reproduction, growth and development of different varieties of Vaccinium corymbosum from the foreign selection. The objects of research were 5 varieties of highbush blueberry: Bluejay, of early ripening period; Bluecrop, Bluegold, Legacy, of average ripening; Aurora, of late ripening. Optimal conditions of explant surface sterilization have been selected depending on their type and effectiveness of used disinfectants. Maximum quantity of viable sterile regenerates was obtained using the mixture of sterilizing solutions of alcohol and bleach "Belizna" with Tween. Effectiveness of

Photosynthetic Pigments in Shoots of Vaccinium Corymbosum L. (Cv. Elliott)

“…Elliot grown on the experimental plot of 'Berry Partner' Ltd. in the village Sokilnyky of Lviv region of Ukraine were collected in the seasons 2017-2018. V. corymbosum plants were obtained by in vitro propagation on Woody Plant Medium (Yavorska et al, 2016). Collection of V. corymbosum c.v. Elliott plant materials, was carried out during flowering (I), fruiting period (II), in autumn after fruiting (III), the period preparation for winter rest (IV).…”
