| Abstract:
Fruit quality of strawberry is influenced by the genotype and the growing environment. Simulations of climate change predict in general an increase of temperature within the next decades. Respective effects were simulated here on strawberry plant growth, yield, and fruit quality by the presence or absence of polyethylene tunnels from the end of winter to the end of harvest. Factorial discriminant analyses of ten cultivars identified the vitamin C content of the fruits, the harvest begin, the leaf/fruit ratio, and the fruit weight as the main discriminating parameters. Based on these results five cultivars (‘Antea’, ‘Asia’, ‘Manille’, ‘Matis’, and ‘Yamaska’) were tested for their response to increasing temperatures; the effect was highest for harvest begin, fruit colour, and vitamin C content. The importance of the response varied between the cultivars. The processes for such different responses as well as the effects on other health related compounds will be further analysed. | |
