A Southern Pine Seed Orchard in the Lower Rio Grande Valley of Texas

An experimental seed orchard of loblolly (Pinus taeda L.) and slash (Pinus elliottii Engelm. var elliottii) pine was established in the lower Rio Grande Valley near McAllen, Texas which is well outside the natural range of these species. The majority of ramets were planted in 1976 with additional material established in 1977. Flower counts made from 1979 through 1982 indicate that a higher number of loblolly flowers per ramet were produced in the South Texas Orchard than in an operational orchard established at the same time in southern Arkansas. Seed analyses did not show the presence of insect pests common to orchards located in the species' natural range.
