Abstract

Da foglie di cetriolo della cv. " Marketer ", presentanti maculature di tipo internervale e paranervale di varia estensione, è stato isolato nella primavera 1967 un batterio di cui è stata accertata la patogenicità, mediante inoculazione artificiale su foglie e frutti. Dalla sindrome riscontrata sulle piante colpite, che erano allevate in una serra del litorale riminese (Forli) e dagli esiti dell'esame microbiologico si ritiene corretto riferire il parassita a Pseudomonas lachrymans (Smith et Bryan) Carsner. From Cucumber leaves of the cv. " Marketer " with variously extending internerval and paranerval spotting a bacterium was isolated in Spring 1967. We have ascertained its pathogenicity through artificial inoculation on leaves and fruits of Cucumber. From the symptoms observed on the diseased plants, which were grown in greenhouses of the Riminese coast-line (Forli), and from the results of the microbiological examination, it appears correct to refer the parasite to Pseudomonas lachrymans (Smith et Bryan) Carsner.
