MYCELIAL GROWTH AND SPORULATION OF Fusarium spp. PATHOGENIC TO Ilex paraguariensis IN DIFFERENT CULTURE MEDIA AND UNDER EXPOSURE TO DIFFERENT LIGHT LEVELS
The aim of this study was to evaluate the effect of different culture media and light levels on mycelial growth and sporulation of Fusarium spp. pathogenic Ilex paraguariensis plants. For the tests, one isolate of F. oxysporum and six isolates of F. solani, were transfected with the following cultur...

Zusammenfassung: | The aim of this study was to evaluate the effect of different culture media and light levels on mycelial growth and sporulation of Fusarium spp. pathogenic Ilex paraguariensis plants. For the tests, one isolate of F. oxysporum and six isolates of F. solani, were transfected with the following culture media: potato dextrose agar (PDA), potato-sucrose agar (PSA), malt extract agar (MEA) and V8. They were exposed to three light levels: 0, 12 and 24h of white light. The V8 and MEA culture media promoted the growth in diameter of the colonies, while the MEA and BSA media contributed to the sporulation of Fusarium spp.
O objetivo deste trabalho foi avaliar o efeito de diferentes meios de cultura e níveis de luminosidade no crescimento micelial e esporulação de isolados de Fusarium spp. patogênicos a Ilex paraguariensis. Para os testes foram utilizados um isolado de F. oyxsporum e 6 isolados de F. solani. Os isolados foram transferidos para placas de Petri contendo os seguintes meios de cultura: BDA, BSA, MEA e V8, em seguida, foram submetidos a três níveis de luminosidade: 0, 12 e 24h de luz branca. Os meios V8 e MEA beneficiaram o crescimento em diâmetro das colônias já o MEA e BSA contribuíram para a esporulação de Fusarium spp. |
