蚕豆火肿病由巢豆油壶菌(Olpidium Viciae Kusano)引起,症状特点是病部产生小瘤状突起。我们对该病的组织病理学研究[1]表明是一种增生型组织病变,病菌仅定殖在侵入叶、茎的表皮细胞内,病菌的侵染引起邻近侵染点的表皮细胞及其下的叶肉细胞或茎的皮层组织细胞转化为分生细胞,并不断分裂增生和细胞体积增大,导致蚕豆病组织
The flamingo beans are caused by Olpidium Viciae Kusano, a symptom characterized by nodules on the surface of the disease. Our histopathological study of the disease [1] showed a proliferative histopathology in which the germs colonized only the epidermal cells that invaded the leaves and stems. The infection of the germs caused the epidermal cells in the vicinity of the infection site Of mesophyll cells or stem cortical cells into meristematic cells, and continue to divide and proliferate and cell volume increases, resulting in broad bean disease tissue
