Virescence disease in Hydrangea macrophylla (florists' hydrangea): graft transmission of the causal agent and symptoms


, : Virescence disease in Hydrangea macrophylla (florists' hydrangea): graft transmission of the causal agent and symptoms. Acta Horticulturae (59): 153-159

Plants of a seedling clone of H. macrophylla were inoculated at monthly intervals by grafting with buds from a hydrangea with virescence disease to determine the relationship between time of inoculation and symptom development. Most of the plants inoculated early in the season showed severe foliage symptoms and some developed flower symptoms during the first season following bud inoculation.
