The content of antocians in Deutzia plants sprouts in phase of compelling repose before and after of air temperature decrease was studied. When the temperature of air was —6 °С the antocians content in sprouts of plants was 39,6—117,2 mg/100 g of dry mass. After decrease of air temperature to —18 °С the antocians content in sprouts increased in average to 19,4 %. It has been determined that in sprouts of more frost resistant plants the antocians content in tissues increase more significant compared whith less frost resistant.

Keywords: Deutzia Thunb., antocians, compelling repose, frost resistance
