Investigation on Phytotoxic Effects of Fungal Metabolites




Mycotoxins, which are metabolites of certain fungi, also inhibit plant growth. In this research, the effects of metabolites of Alternaria alternata, Alternaria solani, Aspergillus niger, Penicillium purpureum and Fusarium sp. on the germination of wheat (Triticum sativum L.), lentil (Lens culinaris Medik.), tomatoes (Lycopersicum esculentum Miller) and cucumber (Cucumis sativus L.) seeds were investigated. According to the results, culture filtrates of the fungi retarded or inhibited germination of the seeds. It was observed that the fungal metabolites considerably suppressed hypocotyl growth. These metabolites retarded the growth of wheat and lentil seedlings which were germinated under natural conditions and planted in the culture filtrates.
