Catkin Growth, Seed Production, and Development of Seed Germinability in Quaking Aspen in Central Alberta

Initial release of seeds of quaking aspen (Populus tremuloides Michx.) differed by 2.5 weeks between 1984 and 1988 but began in both years when catkin moisture content was less than 70%. Germinability of freshly extracted seed increased as the collection date approached the time of release. Artificial ripening increased germination speed of seed collected 8 days before a release.
