Abstract

Seed yield in 8- ad 9-year-old yellow birch varied among families and years but averaged more than 1,500 seeds per tree. Long catkins contained more seed than short ones. Seed quality was poor due to insufficient pollination and to differences among trees in flowering phenology.

Keywords
