Abstract: Thirteen samples of geographical species source of Pinus Elliottii from U.S.A. and five samples of the other Pinus from the south of U.S.A. have been experimented as introduced plants in the areas of Yaan city; and both the variation of the early stage and the tendency of the variation have been analysed and calculased according to the seven-year datum of the experiment, which provides scientific basis for the introduction of Pinus Elliottii and five other samples from the south of U.S.A.
