Abstract:

Non mycorrhizal and preinoculated VA mycorrhizal seedlings of Brassica oleracea were exposed to Fusarium moniliforme at 10, 15, 20, 25% soil moisture contents at 18°C temperature and a light intensity of 1500 lux. Pre inoculated VA mycorrhizal seedlings of B. oleracea showed a significant reduction in pathogenic invasion at 20% soil moisture content by F. moniliforme. Non mycorrhizal B. oleracea plants showed a high degree of susceptibility to pathogenic invasion by F. Moniliforme. Preinoculated mycorrhizal plants showed a significant increase in the dry weight of shoot. Highest pathogenic infections by F. moniliforme occurred at 25% soil moisture contents and a significant reduction in dry weight of shoot was recorded at this soil moisture level. At the same soil moisture level (25%) a significant reduction occurred in VA infections.
