8. Antagonistyczny wpływ Trichoderma viride na grzyby owadobójcze Beauveria bassiana, Isaria fumosorosea i Metarhizium anisopliae w warunkach in vitro - Dariusz Ropek, Anna Krysa, Agnieszka Rola, Krzysztof Frączek Abstrakt. Celem badań było poznanie antagonistycznego wpływu grzyba Trichoderma
viride na wzrost i rozwój grzybów owadobójczych Isaria fumosorosea,
Beauveria bassiana i Metarhizium anisopliae. Badania
przeprowadzono w warunkach laboratoryjnych z wykorzystaniem standardowego
podłoża PDA (Biocorp). Materiał badawczy stanowiły dwa szczepy T. viride
słowa kluczowe: grzyby owadobójcze, Trichoderma viride, grzyby antagonistyczne, efekt biotyczny
Antagonistic effect of
Trichoderma viride Summary The aim of
this study was to determine the effect of Trichoderma viride on
the growth and development of entomopathogenic fungi Isaria fumosorosea,
Beauveria bassiana and Metarhizium anisopliae. The studies were
carried out in laboratory conditions on standard medium PDA (Biocorp). Two
strains of T. viride and two strains of each of entomopathogenic
fungi were used in the experiment. Growth of mycelium of two species of fungi
was investigated by dual culture on Petri dishes. The tested fungi used the
nutritional components of the medium to a different extent, which was visible in their unequal growth. Two strains
of T. viride showed the strongest adaptability and they had the fastest
growth rate. The growth rate of entomopathogenic fungi was significantly
slower. However, their growth was not completely inhibited. Furthermore none of
the tested strains of entomopathogenic fungi adversely affected the growth of
the two strains of T. viride. The most uniform linear growth was
observed in dual culture of T. viride (strain 40) and key words: entomopathogenic fungi, Trichoderma viride, antagonistic fungi, biotic effect |
