  • In this study, we focused on UV-B irradiation (280-320 nm) as a novel disease control method as an alternative to synthetic fungicides. Previous studies have reported that UV-B irradiation is effective in controlling powdery mildew (Podosphaera pannosa) in roses. To optimize the irradiation method to treat rose powdery mildew, we cultivated roses using UV-B irradiation […]

In this sense, methods of manipulating wounded regions to stimulate adventitious roots have most frequently been applied to hardwood species. Our first experiments investigating the role of […]
