Abstract

The use of energy saving measures in greenhouse horticulture let to many questions about crop transpiration. By allowing a higher RH in the greenhouse, a lot of energy can be saved, but this also leads to a reduction in crop transpiration. This is associated with a series of problems in crops which will be discussed in this report. Based on interviews with experts and a literature study the various problems are discussed in more detail. This unveils, that not only RH, but also light quality and quantity are involved. This might point towards the involvement of assimilates (sugars) in the discussed problems. Whether the reduction in radiative heath towards the crop when using LED also leads to a reduction in crop transpiration has not been shown. It seems that this rather stimulates crop transpiration. In this report several methods will be discussed to measure crop transpiration, of which the use of weighing gutters seem the most reliable. In the conclusion of this report, new research direction are recommended, including a better physiological formulation of the discussed problems. This report serves as a bridge between fundamental knowledge and practice and contributes to the advancement of sustainability of the greenhouse horticulture sector.
