Sažetak
The research of light and substrate role in leaf photosynthetic pigments, free proline content and flower quality indices in two gerbera cultivars (Vino and Ruby Red) showed that flower stems were longer in additional lighting treatment, coco’ s peat amended with rice chaff and cultivar Ruby Red. Chlorophyll b concentration was in negative relation to leaf proline content and correlated to longer flower stems. In general, the higher leaf total chlorophyll concentration was related to longer stems, and such flowers have had larger flower heads. Flower head diameter did not differ significantly between cultivars ; it was dependent on light regime, substrate and their interaction.
