Abstract: This invention is a method for inducing early flowering in juvenile phase softwood tree species, particularly those within the genus Pinus. This is accomplished by reducing temperature and photoperiod conditions, during a time in which growth would otherwise be active, so that the tree falls into a quiescent or resting phase short of full dormancy. Early bud set occurs, yet active bud development continues. The resting phase is maintained for a sufficient time for sexual buds to differentiate and form. The plant is then allowed to resume normal growth and flowering. By this method both male and female flowers have been produced in grafted loblolly pine scions as young as three years from seed. Normally little or no flowering occurs in this species until trees are from 15 to 18 years old.
