Geranium robertianum L'Hér. (1789) |

Description |
Deutsch: Geranium robertianum - Einige Blätter färben sich im Spätsommer oder frühen Herbst rot. Diese Farbe ist auf das Vorhandensein von Xanthophyllen zurückzuführen, Pigmenten, die zur Carotinoidfamilie gehören und eine Rolle als Zellschutz gegen durch Chlorophylle katalysierte Photooxidation spielen. English: Herb-Rober - Some leaves turn red in late summer, or early fall. This color is due to the presence of xanthophylls, pigments which belong to the carotenoid family, playing a role of cell protectors against photo-oxidation catalyzed by chlorophylls. Français : Géranium Herbe à Robert - Certaines feuilles virent au rouge à la fin de l'été, ou au début de l'automne. Cette couleur est due à la présence de xanthophylles, pigments qui appartiennent à la famille des caroténoïdes, jouant un rôle de protecteurs cellulaires contre la photo-oxydation catalysée par les chlorophylles. |
