Joel: It is my understanding that radiata pine is very easy to root from
cuttings. In a PhD dissertation out of the University of California
at Berkeley, D.R. Vogler obtained greater than 90% rooting from
cuttings of a wide range of radiatia pine clones. His dissertation
citation is "Vogler, D.R. 1991. Genetic interactions in the radiata
pine - western gall rust pathosytem. PhD Dissertation, UC- Berkeley"
The propagation chapter is chapter 3. I do not know if this research
was published in a journal. One of the most recent cited papers to
easy rooting in radiata pine is: Libby, W.J., Brown, A.G., and
Fielding, J.M. 1972. Effects of hedging radiata pine on production,
rooting, and early growth of cuttings. New Zealand Journal of Forest
Science 2:263-283.
