First, the strawberries dormancy (A) Morphological manifestations of sleep and physiological changes Strawberry into the dormant in late autumn. Hibernation morphological manifestations: the new leaf petiole short, leaf area is small, the old leaves fall, stolons stop happening, plants dwarf. In natural conditions, the dormant state continued until early spring next year. Strawberry into the dormancy, the body growth inhibitory substances - abscisic acid content increased growth promoting substances - ghrelin and gibberellin activity decreased, the starch in the leaves into more soluble sugar, root and short stems stored a large number of Nutrients.
