Prospects for clonal forestry with radiata pine

Australian Forestry, 1984
Summary The advantages of vegetative propagation of forest trees are discussed. The history of the development of such techniques with radiata pine (Pinus radiata) is outlined and a new technique for mass propagation of cuttings of the species described. It is suggested large scale clonal plantations of this species are now possible.

Eucalyptus Breeding for Clonal Forestry

2013
As global demand for wood increases, planted forests will also become increasingly important. Accepting and promoting them as the only way to address the wood scarcity problem and also to help suppress the demand for illegally logged timber from natural forests is a major issue globally.

Clonal Forestry with Tropical Hardwoods

1993
The tropical forests are resources of enormous potential value as fuel wood, timber, and pulpwood. Although half of the forests of the world are in the tropics, the rate of depletion of these forests is a cause for concern.

Arguments for Redwood Clonal Forestry

1993
Some concerned citizens are cautious about clonal forestry because they worry about “fooling Mother Nature”. But Mother Nature normally clones coast redwood (Sequoia sempervirens). Stump sprouts, or sometimes stem sprouts or root sprouts or adventitious shoots, produce multiple copies of successful clones in local clumps for two, three, or even more ...

Genetics, Biotechnology and Clonal Forestry

1993
Early foresters were among the first to understand and apply principles of evolution to practical forestry (Matthew 1831, 1860). Matthew’s first citation appeared 11 months before Darwin sailed on the Beagle, and earlier published observations on the effect of seed origin on the performance of planted trees go back to 1760 (reviewed in Larsen 1956).

Organization and Implementation of a Clonal Forestry Program

1993
A successful large-scale operational clonal forestry program has evolved in eastern Ontario, Canada since 1975. The beginning of this program can be attributed to three main factors: (1) the demonstrated growth of improved hybrid poplar clones in field tests, (2) the developing wood supply shortage of a local pulp and paper mill, and (3) the ...

Genetic variances among clonally propagated populations of tamarack and the implications for clonal forestry

Canadian Journal of Forest Research, 1987
Genetic variances of three tamarack (Larixlaricina (Du Roi) K. Koch.) populations in central New Brunswick were examined using vegetatively propagated materials. The component of variance due to clones within families was large for both 5-year height and survival and was partitioned into additive and nonadditive genetic variances.

Clonal Forestry in the Eucalypts

1993
The earliest operational use of rooted cuttings in plantations of forest trees was not with the eucalypts, since rooted cuttings were used over 100 years ago in Cryptomeria japonica (Ono 1882). This kind of regeneration has been common in plantations of Populus spp. and Salix spp. Currently, however, the largest operational clonal forestry programs are

Past, Present, and Anticipated Applications of Clonal Forestry

1993
Trees are among the few natural resources that can be renewed, and the need for trees and the wood that they provide is continuing to increase with increases in world population and the striving of peoples to maintain or increase their standards of living.

Limit theorems and a general framework for risk analysis in clonal forestry

Mathematical Biosciences, 1997
Use of clonally propagated plantings in reforestation offers management advantages of phenotypic uniformity and high yields. Disadvantages include low genetic diversity and the possibility that the clone or clones chosen are particularly susceptible to attack by an insect or pathogen unforeseen as a problem at the time of clonal selection.
