Abstract

The aim of this research project has been to identify and propagate novel naturally occurring hardwood varieties with decorative wood. As well, we hope worked towards improving the propagation of two known hardwood species for future application in the plantation forestry industry. As such, the main goals of this study have been to 1. Locate and sample trees displaying wood defects, and 2. To subsequently propagate trees with suspected figured wood in tissue culture and 3. To develop efficient propagation techniques for both curly birch hybrid aspen. This paper will outline both the means used to locate trees of interest from diverse regions of British Columbia, the types of figured wood and tissue collected, and the interim results of the regeneration process with respect to successful surface sterilization techniques, plant growth hormone regulator concentrations and ratios that have proven successful in successive stages of propagation (callus induction, shoot induction, root induction, etc.), as well as current shoot induction media trials that we hope will prove successful for certain lines that have shown resistance to shoot regeneration in culture. To date, we have been successful in our collection of figured wood material for propagation in tissue culture, and the plant regeneration process is well underway. Proof of concept has already been established in our laboratory with the regeneration of curly birch from apical buds and leaves. Regenerated curly birch trees are now in their third year of growth, and are displaying the beginnings of curly/abnormal wood traits in the base of their stems. More recently, we have regenerated hybrid aspen using the same protocol for our figured wood lines and determined optimal rooting conditions through rooting experiments in vitro. Finally, this paper will provide directions and implications for further research that will be continued through the BC Forest Science Program in 2005/06.
