Comparison of the mycelial growth of some Phellinus spp. isolates on different agar media
Journal Title: Fragmenta Naturae - Year 2017, Vol 50, Issue
Abstract
The aim of this paper was to examine and compare the mycelial growth of Phellinus spp. The following isolates were used: P. igniarius (marked 1 and 2), P. pini (3 and 4), P. pomaceus (5 and 6), P. robustus (7 and 8) and P. torulosus (9). The growth of the isolates was checked on Potato Dextrose Agar (PDA), Malt Extract Agar (MEA), Wheat Agar (WA) and Sawdust-Wheat Agar (SWA) in order to confirm their suitability for Phellinus. The isolates were incubated at 25°C. The results for the mycelial growth (G) (understood as the average values of the diameters of colonies after ten days of incubation) and short descriptions of the cultures on MEA are presented. The mycelial growth of each isolate was the weakest on MEA (G = 37.3 mm), while it was more abundant on the other media (G > 50 mm). P. pomaceus (G = 64.7 mm) and P. igniarius (G = 59.8 mm) had the highest G. In the case of P. pomaceus and P. igniarius, intraspecies differences were observed on all of the media.
