Fig. 2From: Diversities of decay resistance and n-hexane-extractive contents in seven half-sib families from plus trees in todomatsu (Abies sachalinensis)Photographs of antifungal activity test using a paper disc containing various concentrations of n-hexane extracts. A mycelial disc of Fomitopsis palustris or Trametes versicolor was inoculated on the center of the potato-dextrose-agar medium in a 9 cm petri dish, and paper discs (8 mm in diameter) containing various concentrations (20–3,000 μg per disc) of n-hexane extracts were placed around the mycelial disc (a). Circles indicate inhibition of mycelial growth of F. palustris after 8 days of inoculation by n-hexane extracts (b)Back to article page
