Mark record


In September preceding the seed year, reproductive buds of white spruce can be recognized with the naked eye. The numbers of ovulate buds are a good indication of the prospective cone crop. A method of sequential sampling on a small number of trees, which enables a prediction of cone crop potential on a stand or regional basis, is presented. This advance information facilitates planning of seedbed preparation for natural regeneration, seed collection and artificial reforestation.
