摘要: During a 4.-year field experiment at ihe Experimental Slatton for Arable Farming in Lelystad, the Netherlands, witloof chicory plants, grown root production, were surveyed Ihe presence of epiphylic or saprophytic populations softrot bacteria (Enriniu carotovora and Pseudomonus marginalia) on their leaves. Isolates pectolytic collected frotn leaves identified influence environmental variables was assessed testing hypothesis an increase number isolates plants field. A significant linear correlation (R- = 0,47, n= 20, P 0.002) found regression titne (tnonth) temperature (monthly average). The average monthly growth rate significantly greater than zero during seasoti, indicating bacteria. ratio between Envinia changed growing season from predominance pseudomonads frorn May until July to ati equal Atigust harvest. Erwinia negatively correlated with total global radiation. Ecc later attributed protection high radiation levels adverse temperatures tmicroclimate under canopy. Zusammenfassung Zichoriepflanzen wurden wahrend der Wurzelproduktion einem Freilandversuch auf den epiphytischen Befall durch Nassfaulebakterien pektolytischen Gattungen und Pseudomonas marginalis untersucht, Der vierjahrige Freiland versuch wurde Versuchsstation fur Acker- Gemusebau Niederlande, ausgefuhrt. Isolate Bakterien von Zichorieblattern identifiziert. Effekt Umwelteinflussen das Vorkommen analysiert, ausgehend Hypothese die Zahl Wachstumsperiode Zichoriepflanzen zunimmt. Die Anzahl war mit Zeit (Monate) Temperatur (Monatsmittel) signifikant korreliert (R2= 0.47, 0.002). monatliche Zuwachsrate gesamten Pflanzen positiv, einen steigenden schliesen last. Das Verhaltnis zwischen - Isolaten veranderte einer Mai bis Juli zu zahlenmasig gleichen August zur Ernte Zichoriepflanzen. Strahlungsintensitat negativ ihre Zunahme ab wird Schutz vor schadlichen Strahlungsintensitaten Temperaturen sich schliesende Gewachs erklart.
