Abstract

Seasonal effects on wound susceptibility and canker expansion in honeylocusts inoculated with Thyronectria austro-americana.

Abstract

Field-grown 2-yr-old honeylocust (Gleditsia triacanthos var. inermis) seedlings were planted at a research nursery in Fort Collins, Colorado, and inoculated each month for 2 yr with the fungus Thyronectria austro-americana. Resulting canker sizes were recorded monthly for one year after inoculation. Canker size was largest after summer and autumn inoculation. Canker expansion ceased 7-10 months after inoculation in all seasons except spring (when it ceased after 3-4 months).
