Colours of florets of several gerbera (Gerbera jamesonii Bolis ex Adlam) cultivars measured with a colorimeter

Abstract

The colour variation between several gerbera cultivars were analyzed with a tristimulus colorimeter. A pilot study with a few cultivars showed that the flower colour variation between cultivars and colour effects during the growing season can be calculated quantitatively on the basis of data measured by the colorimeter. On the basis of these results the colour differences between a larger group of gerbera cultivars were measured. A consistent number of cultivars was distinct on the basis of colorimetric data and visual colour assessments.
