Evaluation of Open Pollinated Paper Birch (Betula Papyrifera Marsh.) Seed Sources Grown in Different Containers and Media
Twelve week growth of paper birch seedlings from 50 individual tree sources was evaluated using two container and media types. Growth was significantly greater in Spencer-Lemaire Book Planters than in Plant Band containers. Seedlings grown in Pro-Mix BX were larger than those grown in peat-vermiculite (4:1). Seedlings from plus trees were significantly greater in height and root collar diameter than those from average parents. Regional differences in performance were observed.
