| 摘 要： | 通过对福鼎硖门湾海区坛紫菜病烂情况进行调查、采样和室内培养，运用显微观察方法，研究坛紫菜生理性病变的发生和发展过程。该病主要症状为叶状体梢部颜色逐渐变浅，然后发白、烂化，无明显病灶烂孔；病理表现为叶状体梢部细胞边缘模糊，色素体变色，然后发展为细胞边缘紊乱，细胞溶解，原生质流出，细胞结构失常。病变严重的易引发细菌和原生动物二次感染，造成坛紫菜叶状体出现溃烂，最后完全解离。雨水天气是导致该病变发生的原因，采取剪除叶状体病烂部位和晴好天气延长干出时间是控制该病变的主要措施。

| Abstract: | The rotten disease of Porphyra haitanensis from Fuding Xiamen Bay was investigated in this paper. the samples was collected and took back to culture in laboratory, and then the occurrence and development process of physiological disorder were studied by using microscopy methods. The main symptoms of this dis-ease were faded, pale and then completely rotten in tip part of thallus. No obvious lesions rotten hole was found. Main pathologic symptoms included, in tip part of thallus, cell edge blurred, pigment body color changed and then developed into cell edge disorder, cytolysis, protoplasm outflow, abnormal cellular struc-ture. The severe lesions could easily cause secondary infection by bacteria and protozoa, resulting in ulceration of the thallus, and finally caused the thallus dissociated completely. Rainy weather could easily lead to this disease to break out. Cutting rotten parts of the thallus and extending the drying time in sunny day were the key measures to control this disease. |
