Abstract
Wood pitting symptoms, induced in high proportions of open-pollinated Hyslop and lower proportions of Columbia crab seedlings by inoculation with stem pitting virus, were as severe in the main and lateral roots as in the trunks and branches. Severe wood pitting occurred also in open-pollinated Delicious seedlings, serving as rootstocks for Virginia crab trees used in stem pitting virus indexing trials. The wood pitting of Delicious seedling rootstocks was usually accompanied by stem pitting on Virginia crab, but in 7 of 113 test trees the rootstock only was affected, and in 9 other trees symptoms were more severe on the seedling rootstock than on the Virginia crab trunk. Tree vigor was as effectively reduced by wood pitting of the root systems as by that of trunks and branches.
