| dc.description.abstract | Three genera of the Fungi Imperfecti (<u>Alternaria</u>, <u>Cladosporium</u> and <u>Epicoccum</u>) were isolated in high frequency from the pistillate flowers of white oak. These genera occur worldwide and although several species of each genera are parasitic on crop plants, they are primarily saprophytic in the forest ecosystem. Of the three genera, only <u>Cladosporium</u> is parasitic on <u>Q. alba</u>, causing a leaf mold. Several other genera of fungi were isolated in low frequency from the oak flowers. Included in this group were <u>Penicillium</u>, <u>Pestalotia</u>, <u>Curvularia</u>, <u>Pyrenochaeta</u>, <u>Nigrospora</u> and <u>Fusarium</u>. The effect of fungal spores on pollen germination was investigated. Suspensions of pollen grains and fungi spores were cultured in Van Tieghem cells. Pollen germination <u>in vitro</u> was significantly enhanced by <u>Cladosporium</u> and <u>Epicoccum</u>, but unaffected by <u>Alternaria</u>. | en |
