Abstract:
Responses of 36 crab apple cultivars (Malus
spp.) to inoculation with the viruses apple chlorotic
leaf spot (CLSV), apple stem pitting (SPV),
and apple stem grooving (SGV) are given.
SPV
symptoms occurred in 19, CLSV symptoms in
11, and no external symptoms of SGV were
observed.
These results should be considered
when selecting crab apple cultivars as inter-
planted pollinizers which could be endangered
ecause of natural, root, graft transmission from
virus infected apple cultivars.
