Variation in the Ability of Slash Pine Progeny Groups to Absorb Nutrients1

  1. Laurence C. Walker and
  2. Robert D. Hatcher2



Twenty-seven variables were tested to determine whether five slash pine (Pinus elliottii var. elliottii) progeny groups of known parentage differed in ability to absorb and efficiently utilize nutrients. Fertilization × progeny group interactions were significant for N and K in needles and stems, and for CO2 absorption by needles during the first year of growth in an environmental control room. Phosphorus-32 in stems varied between progeny groups, and relative amounts of P32 absorbed were ascertained from radioautographs.
