Date of earlywood-latewood transition in provenances and families of loblolly pine, and its relationship to growth phenology and juvenile wood specific gravity

Creator:

Jayawickrama, K. J. S., McKeand, S. E., Jett, J. B., and Wheeler, E. A.

Abstract:

When grown together in plantations, fast-growing southern and coastal sources of loblolly pine (Pinus taeda L.)often have lower wood specific gravity than northern and inland sources. This study investigated whether this phenomenon could be explained by a later transition to latewood, associated with a longer period of height growth, of...

Rootstock effects on scion growth and reproduction in 8-year-old grafted loblolly pine

Creator:

Jayawickrama, K. J. S., McKeand, S. E., and Jett, J. B.

Abstract:

Contributions of sites, rootstocks, and scion clones (and the nteractions between these factors) to scion growth and reproduction were studied in loblolly pine (Pinus taeda L.). Twenty-five full-sib families were used as rootstocks. Six scion clones were grafted on them in all combinations. Study sites were three seed orchards in...
