Veränderte Temperaturbedingungen als Folge des Klimawandels und ihre Bedeutung für den Erdbeer- und Himbeeranbau

The importance of the predicted temperature increase as a consequence of change in climate on strawberry and raspberry production is discussed with regard to flower initiation, dormancy and temperature optimum for photosynthesis on the basis of a literature review and temperature data from the location of Geisenheim, Germany. June-bearing strawberry and biennial fruiting raspberry cultivars and remontant cultivars for both species are considered. In the future, problems will be expected for flower initiation of June-bearing raspberry and for breaking of dormancy of strawberry and raspberry cultivars with high chilling requirement. The predicted temperature increase will lead to early flowering and cropping of the berries.
