Observational analysis evaluates seed-borne pathogens in five tree species, suggesting germination impacts.
An important step in the management of plant diseases is seed health testing to detect seed-borne pathogens. The study was carried out to assess seeds of five forest trees (Khaya senegalensis, Acacia senegal, Mansonia altissima, Parkia biglobosa and Adansonia digitata) for seed borne pathogens. Agar plate and paper towel methods were respectively used to isolate the pathogens and determine the germination percentage. Fungal pathogens belonging to seven genera (Rhizopus, Fusarium, Macrophomina, Penicillium, Lasiodiplodia, Aspergillus and Colletotrichum) were isolated and identified. Species of Penicillium and Aspergillus were more dominant on the test tree species. Adansonia digitata recorded the highest germination percentage as well as highest percentage post emergence mortality. Parkia biglobosa had the highest vigour index with Khaya having the least index for vigour.
