title: Winter-hardy sweet cherry cultivars and forms of Nikita Botanical Gardens
abstract: In the Steppe Crimea the formation of archesporial tissue in the anthers of sweet cherry begins in the autumn, when the air temperature declines to 10-16°C. Flower buds stay in this stage all winter and have the highest winter hardiness at that time.
