Studies of Two Seed-Borne Fungi of Some Malaysian Forest Tree Species

Twenty-six species of saprophytic fungi and ten species of potentially pathogenic fungi were isolated from seeds of five indigenous and three introduced forest tree species. Isolation of the fungi using both the blotter and the agar plate methods was carried out to ensure the isolation of as ma...
