Growth response to latent virus infection of apple trees on seedling rootstocks


, : Growth response to latent virus infection of apple trees on seedling rootstocks. Acta Horticulturae (44): 237-244

Chlorotic leaf spot virus and stem pitting virus failed to produce measurable effects on Delicious and Golden Delicious cvs on seedling rootstocks when inoculated into trees alone or in combination. Data obtained during a 5-year study showed that the level of 7 plant nutrients in leaves and the increases in trunk diameter of Delicious trees were not appreciably changed by these viruses. Similarly growth of Golden Delicious trees, fruit yield and appearance were not adversely changed.
