Detection and location of Seed-Borne Fungi of Blonde Psyllium and their Transmission in Seedlings
M. A. Elwakil and K. M. Ghoneem

Abstract:
Eighty-six samples of blonde psyllium seed were collected from commercial markets in Egypt and tested for seed borne fungi. Both blotter and deep freezing methods were used to detect the maximum number of internal and external seed-borne fungi. A total of 41 species of fungi belonging to 21 genera were identified using the two selective methods. The pathogenicity of Fusarium oxysporum, F. solani and F. moniliforme was studied in psyllium seeds and seedlings. Both seed and soil inoculation were used in the studies. A higher percentage of pre- and post-emergence damping off developed from seed inoculation with each of three fungi than from soil infestation. The transmission of Fusarium oxysporum, F. solani and F. moniliforme from seed to mature plants of blonde psyllium was studied. All three fungi were found in root, hypocotyl and lower stem tissues of psyllium plants at intervals of 35, 60 and 120 days post-germination.
