Research of the blackberry (Rubus subg. eubatus Focke) plants cultivars winter-hardiness applying the shoots electrical conductance calculation / Telepen'ko Y. Y. // Sadivnytstvo (Horticulture). Ц 2017. Ц 72. Ц P. 202-209. Ц Refs.: 6. Ц in Ukrainian.

The author presents the results of researching the blackberry 25 cultivars bushes shoots tissues electrical conductance in different periods (at the beginning of the plants dormancy period and after the minus temperatures effect on them). Besides, the exact frostresistance level of studied cvs has been determined in the field conditions under the influence of minimally low temperatures. The analysis of the obtained data has revealed the correlation between the investigated indices, in particular, the dependence of the bushes winter-hardiness on their forms.

Key words: blackberry, electrical conductance of the shoots tissues, frostresistance, adaptive properties, indexed damage point, winter-hardiness.
