Abstract

<abstract abstract-type="main" id="jph12292-abs-0001"> <title>Abstract</title> <p> <italic>In vitro</italic> evaluation was carried out on seed samples of wild and cultivated rocket cultivars, most frequently grown in Italy, and obtained from farms affected by the leaf spot caused by <italic>Alternaria japonica</italic> in Piedmont and Lombardy during the fall of 2010. Twelve seed samples were collected and assayed for the presence of <italic>A</italic>. <italic>japonica</italic>. The pathogen was isolated only from not disinfected seeds. Among the two seed samples of cultivated rocket (<italic>Eruca vesicaria</italic>), only one was infected by <italic>A. japonica</italic> at a level of one infected seed out of 800. Four out of ten samples of wild (<italic>Diplotaxis tenuifolia</italic>) rocket seeds were contaminated by <italic>A. japonica</italic> with the highest level of infection detected in a single sample of 3 out of 800. All tested isolates of <italic>A. japonica</italic> obtained from seeds were pathogenic on both wild and cultivated rocket.</p> </abstract>
