FROST RESISTANCE OF STRAWBERRY VARIETIES IN CONTROLLED CONDITIONS
Abstract
The resistance of strawberry varieties to early winter frosts was studied in the laboratory conditions. It was determined that the temperature lowering till -15°C did not cause irreversible damages of strawberry varieties. In early December the temperature lowering till-20°C intensified the damages of strawberries varieties ‘Solovushka’ and ‘Sara’ to 3 rating, ‘Alba’ to 4.5 rating and ‘Marmolada’ to 4.2 rating. During the winter it was determined that the strawberry reaction was intensified on the thaw by the end of the winter period. As a result of the experiment it was revealed the strawberry varieties ‘Solovushka’ and ‘Sara’ with the greatest level of frost resistance.
