Temperature requirement for germination of conidiospores and growth of mycelia of Heterobasidion annosum s.s. and Heterobasidion parviporum

Different temperature requirements of the two species Heterobasidion annosum (Fr.) Bref. (P group) and H. parviporum Niemelä & Korhonen (S group) should explain why the distribution areas are different in Scandinavia despite of a wide range of distribution of their host species Picea abies and Pinus...

description Different temperature requirements of the two species Heterobasidion annosum (Fr.) Bref. (P group) and H. parviporum Niemelä & Korhonen (S group) should explain why the distribution areas are different in Scandinavia despite of a wide range of distribution of their host species Picea abies and Pinus sylvestris up to 68°N. Temperature ranges of P and S were observed. Germination percent, length of the germination tubes of the conidiospores and growth rate of the mycelia were measured for 6 individual strains of the S and P group, respectively. When sampled, mycelial strains of the S group showed a significantly faster growth rate at 22°C compared to the strains of the P group. Germination percent and length of the germination tubes of the conidiospores were insignificant at all temperatures. In conclusion, growth rate of the S group increased with temperature until 27°C and increase of the growth rate of the P group stagnated after 22°C. The S group had a wider temperature range than the P group.
