Effects of propamidine on the ultrastructure of Botrytis cinerea Pers
丙烷脒对番茄灰霉病菌超微结构的影响

Effects of propamidine on cell ultrastructure of Botrytis cinerea Pers. were examined by means of electron microscopy techniques. The studies revealed that propamidine not only inhibited the hyphal growth, but also caused a series of marked hyphae morphological and cell structural alterations. These changes are generally irregular swelling, excessive branching and many tumors on the surface of hyphale, considerable thickening of the hyphal cell walls, particularly at the hyphal tip region, vacuoles and electrondense bodies increasing, excessive mitochondrion irregular swelling, and so on. Above cytological change resulted in the necrosis of hyphal cell.
