  • Breeding of modern rose cultivars decreases the content of important biochemical compounds in rose hips [Elektronski vir]
    Kunc, Nina ...
    This study aimed to determine the content and composition of bioactive compounds in autochthonous rose hips (R. pendulina, R. spinosissima, and R. gallica) and to compare them with the content of ... bioactive compounds in some cultivars (‘Harstad’, ‘Bourgogne’, ‘Mount Everest’, ‘Poppius’, ‘Fruhlingsduft’, ‘Single Cherry’, ‘Fruhlingsmorgen’, ‘Violacea’, and ‘Splendens’) derived from these main species. Due to insufficient information on how bioactive compound content changes when crossing roses, this study also sought to ascertain whether modern rose hip cultivars are still a sufficiently rich source of bioactive compounds and could, therefore, be potentially used as a functional food. All material was collected in the Arboretum Volčji Potok (Slovenia). The ascorbic acid content was highest in the ‘Harstad’ cultivar (12.79 g/kg FW), and the total organic acid content varied from 1.57 g/kg FW (R. spinosissima) to 34.39 g/kg FW (‘Harstad’). Of all the carotenoids analyzed, only lycopene and b-carotene were present in all the samples. The total carotenoid content was highest in the ‘Fruhlingsmorgen’ cultivar (100.84 mg/kg FW), derived from R. spinosissima, and lowest in the main species, R. spinosissima (9.26 mg/kg FW). It can be concluded, therefore, that the content of bioactive compounds in rose hips of modern cultivars is generally lower than in rose hips of old cultivars and original species included in this study. The research results confirm that modern breeding strategies are mainly focused on goals such as abundant flowering and resistance to diseases and pests and not so much on the content of bioactive compounds.
