摘要

An estimation of the virus sanitary situation of stone and pome fruit mother-tree plantations by ELISA was undertaken in 1992 and 1993 for the first time in Greece. State and private plantations were visited and samples were collected from 387 stonefruit and 376 pome fruit trees. At least one tree from each variety included in the state collections was sampled, whereas private mother tree orchards were sampled at approx. 6% of total trees. ELISA was used to test for plum pox potyvirus (PPV), prunus necrotic ringspot ilarvirus (PNRSV) and apple chlorotic leaf spot trichovirus (ACLSV) in stone fruit samples, and apple mosaic ilarvirus (ApMV), apple stem grooving capillovirus (ASGV) and ACLSV in pome fruit samples. Virus incidence greatly differed according to the location of the plantations. In the case of viruses possessing a natural means of dissemination, the most serious problems were encountered when mother trees were located near commercial orchards. PPV and PNRSV incidence in peach trees inNaoussa, Imathia (northern Greece) rose to 100 and 48%, respectively; PNRSV incidence in almond trees in Volos, Magnissia (central Greece) to 94%. Peach and almond plantations away from production areas showed lower virus incidences (ranging from 0-33%)and they could be sanitated by careful indexing and further eradication of infected trees. Isolated apricot mother tree plantations in Argolida county (southern Greece) were free of PPV, whereas in the nearby Korinthia county, the PPV incidence was 1%.ACLSC, which is only disseminated by the infected propagation material, was most prevalent in pome fruits with an incidence ranging from 29.4-100% in apple trees and from 20-27% in private pear plantations. ApMV incidence in apple trees was 2.7-10.6% andthat of ASGV, identified for the first time, was 0-14.7%.
