Abstract

Evaluates storage and germination environments of Coreopsis lanceolata. Highest total germination and most rapid and uniform germination of seed occurred at constant 15C. Recently harvested seeds had 44% total germination. Plant growth regulators (giberellic acid, ethephon, or kinetin) increased germination and reduced the number of germination days by 50%. Storing fresh seeds for greater than 6 months also increased total germination (seeds stored at 5C and 10% to 20% relative humidity (RH), or 15C at 20% to 35% RH). Higher seed storage temperatures led to increases in the time it took to reach total germination.
