Notes: Germination Characteristics of Red Maple in Northwestern Ontario
Abstract:Immediately after dispersal in June, seed from 12 trees at the northwestern limit of red maple's (Acer rubrum L.) range were chilled for 0, 33, or 90 days and subsequently incubated at 5°-15°C or 20°-30°C. An average of 44 percent of the unchilled seed germinated at 5°-15°C, and 2 percent germinated at 20°-30°C. Thirty-three days chilling resulted in 72 and 27 percent germination at 5°-15°C and 20°-30°C, respectively, and 90 days chilling promoted almost complete germination under both temperature regimes. Rechilling ungerminated seed for 90 days after incubation resulted in their germination. There were major family differences in germination characteristics. Forest Sci. 30:670-672.
