Roses (Rosa spp.) are widely cultivated in Italy for ornamental and aesthetic purposes. In autumn 2020, petal brown spots on rose buds especially on petals were observed in outdoor potted plants in Tuscany (Italy), causing aesthetic damage compromising marketability of cut flowers. A study about morphological and phylogenetic features of the disease-associated fungus, followed by a pathogenicity assay according to Koch's postulate, was carried out. The recently described Fusarium clavum (FIESC 5) was found to be the causal agent of petal brown spot disease on rose buds in Tuscany, Italy.

玫瑰:镰孢镰刀菌F. incarnatum-equiseti种复合体5)的新寄主植物,引起花瓣褐色斑点

玫瑰(Rosa spp。)在意大利广泛种植,用于装饰和美学目的。在2020年秋季,在意大利托斯卡纳的室外盆栽植物中观察到玫瑰花蕾上的花瓣褐色斑点,尤其是花瓣上的褐色斑点,对美学造成损害,损害了切花的适销性。对疾病相关真菌的形态和系统发育特征进行了研究,然后根据科赫的假设进行了致病性分析。在意大利的托斯卡纳,最近描述的镰孢镰刀菌(FIESC 5)是玫瑰芽上的花瓣褐斑病的病原体。
