Jayawickrama, K. J. S.; McKeand, S. E.; Jett, J. B.; Wheeler, E. A. (NRC Canada, 1997-07)

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 ...

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

Jayawickrama, K. J. S.; McKeand, S. E.; Jett, J. B. (NRC Canada, 1997-11)

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 ...
