摘要

The disorder was observed in 2 apricot orchards of cv. Tirynthos grafted onto Myrobalan with cv. Stanley as intermediate stock in the southernmost part of Apulia, Salento peninsula, Italy. Affected plants (50 out of 880) showed bushy growth with small leaves that turned chlorotic in summer. The fruits were fewer but larger than normal and tasteless. The bark of the trunk and main branches showed extensive splitting, was spongy and much thicker than that of healthy trees. Upon removal of the cortex,the woody cylinder of the scion, but not of the rootstock, exhibited a clear-cut pitting. There was no appreciable difference in the relative diam. of scion and rootstock. All symptomatic plants were infected by prunus necrotic ringspot ilarvirus (PNRSV) as identified by mechanical transmission to herbaceous hosts and ELISA. Graft transmission trials to woody indicators are under way.
