Germination of Basidiospores of Fomes pini on Pine Wood Extract Media

Key Points

Eighty percent of basidiospores germinated in xylem extracts from weevil-killed leaders.
The extracts' pH was optimal for germination, influencing Fomes pini’s growth conditions.
Significant germination differences were observed based on the age of weeviled branches, reflecting their viability.
Germination rates dropped to 0-2% in extracts from lateral branches dead for five years, highlighting age-related effects.

Abstract

Abstract Weevil-killed leaders and dead lateral branches of Pinus strobus L. were compared as infection courts for Fomes pini . Eighty percent germination of basidiospores occurred on media containing cold water extracts of xylem from bases of weeviled leaders dead 1 to 20 years and lateral branches dead 10 or more years. Germination on similar media containing extracts from bases of lateral branches dead 1 year was 40 percent and on those dead 5 years was 0 to 2 percent. The pH of extracts from both weeviled leaders and bases of lateral branches was within a range favorable for germination.
