Institut für Nutzpflanzenwissenschaften und Ressourcenschutz (INRES) der Rheinischen Friedrich-Wilhelms-Universität zu Bonn Activity of fungal and bacterial endophytes for the biological control of the root-knot nematode Meloidogyne graminicola in rice under oxic and anoxic soil conditions Inaugural – Dissertation zur Erlanggung des Grades Doktor der Agrawissenschaften (Dr.agr.) der Hohen Landwirtschaftlichen Fakultät der Rheinischen Friedrich-Wilhelms-Universität zu Bonn Vorgelegt am 09.03.2010 von Le Thi Thu Huong aus Ho Chi Minh city, Vietnam Referent: Prof. Dr. R. A. Sikora Korreferent: Prof. Dr. M. Becker Tag der mündlichen Prüfung: 29.04.2010 This work is dedicated to my family!Activity of fungal and bacterial endophytes for the biological control of the root-knot nematode Meloidogyne graminicola in rice under oxic and anoxic soil conditions Two endophytic Fusarium moniliforme isolates Fe1 and Fe14, an endophytic bacterium Bacillus megaterium Bm and a rhizosphere Trichoderma isolate T30 with known antagonistic activity toward the root-knot nematode Meloidogyne graminicola were studied for bio-enhancement of rice under glasshouse conditions. The level of colonization of Fe1 and Fe14 in the rice root under oxic and anoxic soil environments was investigated.
