Inbreeding Experiments in Sugar Maple (Acer Saccharum Marsh.) -- Early Results

Basic to any pollination work is a thorough knowledge of the flowering and fruiting behavior of the species with which the breeder plans to work. For sugar maple, an unpublished exploratory study by the author in 1958, involving both field observations and a search of the literature on the species reproductive processes, pointed up the need for research on its flowering and fruiting behavior. That exploratory work also was helpful in outlining the objectives and procedures to be used in a second and more intensive investigation. This paper is a report on one phase the more intensive and more comprehensive second study. namely, on the incidence of self-fertility and the characteristics of selfed progenies in the early seedling stages.
