Abstract EN
Plants from the Allium genus are valued worldwide for culinary flavor and medicinal attributes.
In this study, 16 cultigens of bunching onion (Allium fistulosum L.) were grown in a glasshouse under filtered UV radiation (control) or supplemental UV-B radiation [7.0 μmol·m−2·s−2 (2.68 W·m−2)] to determine impacts on growth, physiological parameters, and nutritional quality.
Supplemental UV-B radiation influenced shoot tissue carotenoid concentrations in some, but not all, of the bunching onions.
Xanthophyll carotenoid pigments lutein and β-carotene and chlorophylls a and b in shoot tissues differed between UV-B radiation treatments and among cultigens.
Cultigen “Pesoenyj” responded to supplemental UV-B radiation with increases in the ratio of zeaxanthin + antheraxanthin to zeaxanthin + antheraxanthin + violaxanthin, which may indicate a flux in the xanthophyll carotenoids towards deepoxydation, commonly found under high irradiance stress.
Increases in carotenoid concentrations would be expected to increase crop nutritional values.
