The strawberries in the Innovation and Demo Centre ( IDC ) Taste at Wageningen UR Greenhouse Horticulture in Bleiswijk were planted on January 20th and the first fruits will be harvested soon.

The varieties Elsanta, Sonata, Darselect and Honeoye were chosen because differences in flavour and healthy compounds were anticipated between the varieties. In order to compare them with each other, they will be harvested in more or less the same period.

Different strategies with artificial lighting

Three different strategies with artificial lighting are being used to influence fruit composition and taste. In the first place, LED top lighting is situated at the top of the greenhouse with an intensity of about 90 μmol/m2/s. In a different strategy LED lighting hangs about 30 cm above the crop and in combination with top lighting, produces over 230 μmol/m2/s at the leaf level. The last strategy is LED interlighting, from which light partly shines on the leaves and fruits. Hopefully, the harvested fruits will contain additional compounds to improve the taste and/or health. This will be analysed by instrumental measurements and taste panels .

Saturday, May 10th 2014, the Innovation and Demo Centre (IDC) Flavour will be opened for Dutch consumers with a large fruit and vegetable market “Feast of Flavour!”. A large number of activities are being organized around taste and the greenhouse with strawberries will be opened for visitors.
