A stand of longleaf pine in Suffolk County, Virginia was visited November 13-14, 1997 and mature cones gathered by clipping the tips of branches with an extension pole. Two thousand six hundred fourteen seeds were obtained from 121 cones with an average yield of 21 seeds per cone. One thousand seven hundred forty eight seeds were used in an experiment to determine whether hydrogen peroxide would provide significantly greater germination than controls. Seeds were sown in greenhouse beds in mid-December and covered to a depth of 1/4 inch with soil. Germination commenced within one week and by the end of January there was no significant difference between the treatments with germination averaging 52%.
