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 CO 2 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 P 32 absorbed were ascertained from radioautographs.
