Fusarium species of Turkey

In this study, the researches which were made with Fusarium species in Turkey were reviewed and it was indicated that 28 Fusarium species were determinated in 34 plant species. INTRODUCTION Fusarium species form the most widespread fungi gmups in nature. They live . in several forms on organicmaterialsin every kind of soil from the poles to the equator (Maraite et al., 1973; Kranz et a1., 1977). Some of the species are real parasites. These fungus spccies are determinedas the pathogen in the all organs of wild and cultivated plants. The symptoms differ according to the organs and species of the plants. However, the most visible symptoms appear as rodt rots or wilts. Some Fusarium speciesas F. avenaceum, F. culmorum, F. monili-forme, F. e ~ uiseti are able to infect many plants without distinguishing the plant species. Some spccies are specialized in the genus of, species of, even varieties of the certai ,plants.For example,F. coeruleum,F. eumartii andF. sambucinum are specializedin potato,F. buharicumin cotton,F. xyllarioides . j' 10 coffee. ~ / A1though the Fusarium species appear on the ,several plants organs, the main place where theyare present, is the soit. They get into the plants by this way. They can live in soit for many years because they produce the resistant spores in the soit. ~) Trakya Universitesi Ziraat Fakultesi Arastirma Gorevlisi (**) Harettepe universitesi EAitim Fakultesi OAretim uyesi.
