Abstract
The light requirement for germination of loblolly pine seeds can be met during stratification or germination. One hour of irradiation with light at a avelength of 660 nm and an intensity of 600 ergs/cm2/sec fulfilled the light requirements for germination of seeds stratified for 28 days. Fifteen minutes of the same light at an intensity of 2000 ergs/cm2/sec was adequate when the stratification period was only 15 days. Exposure of seeds to light during stratification neither hastened nor increased germination in light.
