| Abstract: | In order to develop large areas of raw material forest of Taxus yunnanensis for medicinal purposes,it is a fact that superior individual trees with high biologic yield,high alcohol content of Japanese yew and high resistance are selected from Taxus yunnanensis natural forest to set up cutting orchard to provide materials for breeding.Based on the data collection,the paper proposes 3 criteria for preliminary selection of elite individual tree of Taxus yunnanensis namely qualitative requirement on form quality index;biomass index fitting fine regressive mathematic model to achieve the lowest basic point and base line map;the ratio & strength of selection for alcohol content of Japanese yew of small branches to be calculated according to the preselected colony,hence to reckon the criterion for selecting alcohol content of Japanese yew. |
