The technique and numerical law of testing the seed quality of Phellodendron chinense are explored theoretically and practically in this paper.The results indicate that the seed vigor and germination ability can be tested by X ray contrast method (Xc method).Between the seed germination percentage (Ga) and Xc vigarbility (Xv) ,the linear correlative relation is Ga=0.941 7 Xv-10.001, with the contrast conditions of 20%～30%BaCl 2,20～40℃ and 5～7 h and the judging standards are given. In testing seed vigor index (Vi) , two quantitative indexes are determined,which are the seed length (L) and the Xc vigarbility. Moreover, the nonlinear model, Vi=0.000 1 L 1.887 4 Xv 1.749 5 is established.
