Because of the increasing importance of the kiwifruit (Aetinidia deliciosa) as a commercial crop in Italy, and the risk that plants are exposed to when intensively grown in a new region, we tested actinidias for reaction to some common viruses in Italy and screened some plantations for possible virus diseases in Piedmont (North-West Italy). Out of 17 viruses inoculated in young Actinidia plants, tobacco necrosis and tobacco rattle viruses produced continuously growing lesions on inoculated leaves, while cucumber mosaic virus caused systemic leaf chlorosis and stunting. Over 100 samples from filed-grown Actinidia were inoculated to test plants, but no virus could be isolated. It is suggested that Actinidia, in common with other members of the order Guttgerales, may possess some resistance to virus infection.

Abstract
Because of the increasing importance of the kiwifruit (Aetinidia deliciosa) as a commercial crop in Italy, and the risk that plants are exposed to when intensively grown in a new region, we tested actinidias for reaction to some common viruses in Italy and screened some plantations for possible virus diseases in Piedmont (North-West Italy). Out of 17 viruses inoculated in young Actinidia plants, tobacco necrosis and tobacco rattle viruses produced continuously growing lesions on inoculated leaves, while cucumber mosaic virus caused systemic leaf chlorosis and stunting. Over 100 samples from filed-grown Actinidia were inoculated to test plants, but no virus could be isolated. It is suggested that Actinidia, in common with other members of the order Guttgerales, may possess some resistance to virus infection.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
