Effect of Soaking, Moist Chilling, and Temperature on Germination of Striped Maple (Acer pensylvanicum) Seed Anthony Bourgoin and Dale Simpson Canadian Forest Service Fredericton, NB
Data Analysis Total germination at 8 weeks Data transformed by arcsin square root Data analyzed using SAS
Impact of Soaking Time on Seed Moisture Content Soaking time (hrs)Seed MC (%) 0 7.9 4858.7 7263.5 9665.8 Results
Seed lot Mean germ. Soak time Mean germ. Chill time Mean germ. Germ. temp. Mean germ. 117 *65 a 1 052 a1648 a 5/1590 a 12058 a4857 b2459 b20/3023 b 118 *53 b7259 b3262 c 11968 c9658 b 123 *39 d 1 means with different letters are significantly different at P=0.05 * single-tree collection
Conclusions Soaking seed for 48 hours was sufficient to promote high germination Moist chilling for 16 weeks was adequate to promote high germination Seed germination was maximized at temperatures of 5/15°C Secondary dormancy was induced at germination temperatures of 20/30°C
