Early Flowering and Seed Production in Plantations of Sugar Maple

Early flowering and seed production are important factors in tree-breeding experiments leading to the genetic upgrading of planting stock. Reforestation programs that make use of genetically improved stock require orchards that consistently produce heavy crops of flowers and seed. But very little information is available on the earliness of flowering and seed yield in sugar maple (Acer saccharum Marsh.). This is especially true among plantation-grown trees of both graft and seedling origins. I have made observations on trees of one plantation of sugar maples of graft origin and two plantations of seedling origin, and found that grafted sugar maples, between the ages of 3 and 8 years, are capable of flowering heavily during a peak year. But trees of seedling origin, with one exception, have not flowered after 21 growing seasons.
