Supplemental Mass Pollination to increase Seed Yields in Loblolly Pine Seed Orchards

Abstract

Abstract Supplemental mass pollination was evaluated in a young and a mature loblolly pine (Pinus taeda L.) seed orchard in two successive years. Supplemental mass pollination reduced both conelet and ovule abortion in one year in the young seed orchard and resulted in a 222 percent greater potential seed yield than untreated check ramets. The response was small and statistically nonsignificant in the other year. The potential seed yield was not increased in either year in the mature seed orchard.
