DEVELOPING IMPROVED NURSERY CULTURE FOR THE PRODUCTION OF ROOTED CUTTINGS OF CANADA YEW (Taxus canadensis Marsh.)

摘要

Since the early 1990s, when the first anti-cancer drug containing paclitaxel was marketed, yew species (Taxus spp.) around the world have been threatened by unsustainable harvesting practices. Canada yew (Taxus canadensis Marsh.) a species native to eastern Canada and the north eastern United States is now facing similar pressures. In response to an increasing demand for biomass, in 1997, a domestication program was started. In 2003, a series of nursery trials was initiated to evaluate the potentialof several plant growth regulators and cultural treatments for improving rooting of recalcitrant clones. This poster reports initial results from these trials.
