Factors Affecting the Incidence and Development of Black Seed Rot of Slash Pine Caused by Lasiodiplodia theombromae

A study was initiated in the fall of 1988 to determine the incidence of diseased seed occurring in seed orchard trees before cone harvest, and the impact of cone harvesting practices on the incidence of seedborne fungi and the development of disease in seed. Four ramets of four slash pine clones (16 trees total) were selected. in a north Florida seed orchard. Cones were harvested from each tree on three dates (8/31, 9/14, 9/26) and were divided among three treatments.
