Abstract
The ability of the nematode antagonistic, mutualistic endo-phyte Fusarium oxysporum strain 162, to colonize the endorhiza of different Fusarium wilt resistant and susceptible cultivars of tomato (Solanum lycopersicon L.) was investigated. The fungus colonized the endorhiza of both wilt resistant and susceptible cultivars of tomato. Colonization after 3 weeks ranged from 40% to 100% in trial 1 and from 32% to 75% in trial 2. Percent colonization declined 6 weeks after fungal inoculation in resistant as well as susceptible varieties. Biocontrol presented by nematode penetration in trial 1 and number of galls in trial 2 reached 82% and 55%, respectively. Surprisingly, the level of nematode control in Fusarium wilt resistant cultivars was found similar or even higher in some cases when compared to that in wilt susceptible cultivars. Although endophyte colonization decreased over time, the antagonistic fungus reduced Meloidogyne incognita infestation significantly in the majority of the cultivars tested.
Zusammenfassung
Ziel der Untersuchung war es festzustellen ob der gegen Nematoden wirkenden mutualistischen Endophyten Fusa-rium oxysporum 162 fähig ist, verschiedene gegenüber Fusariumwelke resistenter bzw. anfälige Tomatensorten (Solanum lycopersicon) zu besiedeln. Der Pilz besiedelte die Endorhiza sowohl der resistenten wie auch die der anfälligen Tomatensorten. Nach drei Wochen die Besiedlungsrate zwischen 40% und 100% in Versuch 1 bzw. zwischen 32% und 75% in Versuch 2. Der Anteil besiedelter Pflanzen nahm sechs Wochen nach der Pilzinokulation sowohl bei resistenten als auch anfäligen Sorten ab. Die biologische Bekämpfung bewirkte in den beiden Experimenten eine Reduzierung der Eindringung um 82% bzw. der Gallenbildung um 55%. überraschenderweise war in einigen Fällen die Nematoden-bekämpfung bei den resistenten Sorten vergleichbar oder sogar höher als bei den anfälligen Sorten. Obwohl die Besiedlung durch den Endophyten im Verlauf der Zeit abnahm, reduzierte der antagonistische Pilz signifikant den Befall durch M. incognita bei der Mehrzahl der getesteten Tomatensorten.
