Abstract

In a study carried out by Wageningen UR Greenhouse Horticulture & Flowerbulbs, the effects of the light intensity of LEDs and the CO2 content in the greenhouse air have been investigated on photosynthesis, production and quality in the raspberry varieties Kwanza and Lagorai in a November planting. For a realized CO2 content of 775 ppm, 10 times as much CO2 had to be dosed than for a CO2 content of 460 ppm. However, the effect on production was minor or absent. A light intensity of 137 compared to 100 μmol.m-2.s-1, the production in the 2 varieties increased by almost 12% with 15% more PAR light from the sun and LEDs over the total period. There were large production differences between the varieties. The LAI of Lagorai was with more than 7 m-2.m-2 very high.
