Effects of Temperature on the Germination of Selected Wildflower Seeds1
Year: 1982
Type: article
Abstract: Seeds of Coreopsis tinctoria Nutt., Ipomopsis rubra (L.) Wherry, Linum perenne L., and Asclepias tuberosa L. were germinated under constant light at 155 ± 10 μEm −2 sec −1 on a thermogradient plate to determine optimum temperatures for germination. Optimum temperatures were 30°C for C. tinctoria , 25° for L. perenne and 30° for A. tuberosa . I . rubra exhibited poor germination at all temperatures in light. C. tinctoria, L. perenne and A . tuberosa germinated within temperature ranges of 15° to 35°, 15° to 25°, and 25° to 35°, respectively. A. tuberosa was the slowest germinating of the 3 species.
