Abstract

Bacteria are frequently associated with freshly ejected ascospores of Hypoxylon pruinatum, and are capable of reducing or preventing ascospore germination. In Minnesota 72% of the cankers had perithecia contaminated with bacteria and bacteria increased when stromata were kept moist continuously. When bacteria were suppressed spore germination was increased as much as 94%. Bacteria isolated from healthy bark also inhibited ascospore germination and may prevent establishment of Hypoxylon pruinatum in aspen.
