During the period of seed storage in 2019, stored Fraxinus angustifolia and F. ornus seeds showed signs of infection and fungus Epicoccum nigrum was isolated from mould and necrotic lesions on the seeds. In order to confirm the pathogenicity of E. nigrum towards F. angustifolia and F. ornus seeds, an experiment that included inoculation of seeds with E. nigrum and the assessment of germinability was performed. The inoculation with E. nigrum strain caused mould to around 20% of F. angustifolia and 58% of F. ornus, necrotic lesions to 96% of F. angustifolia and 92% of F. ornus, and decrease in germinability to 95% of F. angustifolia and 97% of F. ornus seeds. This study presented, for the first time, the ability of E. nigrum to cause high infection rates and reduced germinability of the F. angustifolia and F. ornus stored seeds. The transmission routes and possibilities for preventive strategies were discussed.

Epicocccum nigrum 对贮藏条件下狭叶白蜡树和山白蜡树种子的破坏

2019年种子贮藏期间，贮藏的沙曲柳和山茱萸种子出现感染迹象，从种子霉菌和坏死病灶中分离出真菌Epicoccum nigrum 。为了确认大肠杆菌的致病性。 nigrum朝向F。 沙枣和F. _ ornus种子，进行了一项包括用E. nigrum接种种子和评估发芽能力的实验。用E接种。 龙葵菌株导致霉菌达到F的 20% 左右。 沙枣和 58% 的F。 ornus , 坏死病变达 96% F . 沙枣和 92% 的F。 ornus，并且发芽率下降到F的 95% 。 沙枣和 97% 的F。 红花种子。这项研究首次展示了E的能力。 nigrum导致F的高感染率和降低的发芽能力。 沙枣和F. _ 鸟储存的种子。讨论了传播途径和预防策略的可能性。
