    Abstract

    Abstract In Bleiswijk, researched is done on the effect of supplemental lighting with lamps (700-800 nanometer) just at the end of the day period (15.30 - 16.00) and at the beginning of the night period (16.00 - 16.30) on spherical leaves of chrysanthemum. There are single flower chrysanthemums grown. Varieties: Anastasia Anastasia lilac and Anastasia white. In addition, on a practice company in the village of De Lier and in one cultivation in Bleiswijk research is done on the effect of supplemental lighting, during last 4 cultivation weeks with Retrofit lamps (700-800 nanometer, Lemnis Lighting), during the day period (04.00 - 16.00). In all crops is little spherical leaves occurred. However, it is noted that the extent to which a certain trend, spherical leaves prevents greater, if right after the day period is lit with lamps (700-800 nanometer). It turns out, that gives no positive effect on the lamps (700-800 nanometer) underexpose by the weight of the stems. It turns out, that by exposing the beginning of the night period with after the lamps (700-800 nanometer) number of side shoots and weight of the side shoots decreases, the percentage the length of the stems are longer, the reaction time shorter and dry matter of the plants is higher. There are no differences in crop development found if during the day period is lighted. This research is financed by Productschap Tuinbouw. © 2012 Wageningen, Stichting Dienst Landbouwkundig Onderzoek (DLO) onderzoeksinstituut
