Resistance of Twenty-one Sweetgum Families to Botryosphaeria ribis

Abstract

Botryosphaeria ribis caused cankers and branch mortality in all sweetgum (Liquidambar) families inoculated in an open-pollinated progeny test. The highest infection occurred in the 21 sweetgum families inoculated in September (78%), followed by November (54%), and May (43%). There was no significant difference among sweetgum families. Some families were more susceptible than others at certain dates.
