Time of flowering (number of days between start of forcing and 10% CS), flower homogeneity (number of days between 10 and 90% total flowering) and maximum percentage of OFs (max. % OF)1 for R. simsii ‘Nordlicht’ and R. simsii ‘Sachsenstern’ under different light conditions.

1Maximum percentage of OFs is the percentage of OF at full bloom (before flowers started to wilt). 2Light conditions during flowering were: forcing at natural light conditions (F), forcing at optimal light conditions with 16 h supplemental light (SON-T, 75–80 μmol m-2 s-1 at plant canopy level) (FA), and post-production flowering (FAL) where FA plants with CS were placed in a growth chamber under controlled conditions mimicking growing conditions similar to those in the consumer’s home (19.8 ± 0.4°C, 73.7 ± 9.5% RH, and 18 h light at 11 μmol m-2 s-1). 3Means (n = 10) within a column followed by different letters are significantly different (p = 0.02, Mann–Whitney U Test).
