Asexual Reproduction Method
Asexual Reproduction

    By using our patented Asexual Reproduction Method, developed by our founder and President, Zhiguo Wang, we are able to accelerate the commercial viability of a yew tree, so that it is able to be used for commercialization starting in approximately three years, compared to more than 50 years for naturally grown yew trees. Our patented Asexual Reproduction Method functions through cell replication with identical genes, sometimes referred to as cloning, of Northeast Yew with only a single parent present.  Using our patented Asexual Reproduction Method, we are able to more than replenish the number of yew trees we cultivate and put into production.

    Mr. Wang first studied yew cloning techniques in 1982, for the purpose of addressing the long reproduction time, low reproduction rates and weak survival rates for yew trees in general. With the support of the Ministry of Forest and Science, and the Technology Department of Heilongjiang Province, Mr. Wang successfully completed a project from 1984 to 1995 for asexual cultivation and cloning technology of the yew, and developed the first artificial cloned yew forest in the world. Tests conducted by the Ministry of Educationí»s Key Laboratory of Forest Plant Ecology in Northeast Forestry University have shown that the growing cycle of a cultivated yew is significantly shorter than that of a natural yew and the concentration is taxol is higher.

    On September 21, 2011, the SIPO granted HDS a patent for í░Northeast Yew Asexual Reproduction Methodí▒, or the Asexual Reproduction Method. This patent is valid for 20 years, from September 30, 2010 through September 29, 2030.    

    We believe that our patented Asexual Reproduction Method has three unique advantages:

    First, the Asexual Reproduction Method addresses the low rooting rate problem and accelerates the seedling rate and the maturity period for Northeast yew. It increases the rooting rate to over 80% and the seedling rate to over 85% for Northeast yew. It can bring the Northeast yew to maturity and ready for commercialization for medical use in as little as two-to-three years, compared to more than 50 years for naturally growing yew trees.

    Second, large colonies can form to out-compete other organisms for nutrients. The active ingredients in the offspring were relatively stable with little difference.

    Finally, there is high chance of survival of the offspring with little variation.
