ABSTRACT
<p><b>OBJECTIVE</b>To screen the optimized methods for detection seed viability and germination rate determination of Atractylodes macrocephala, and determine the relationship between seed viability and germination rate.</p><p><b>METHOD</b>There were four methods, which including 2,3,5-triphynel tetrazolilum chloride (TTC) staining, red ink staining, BTB staining and Nongjia method, to evaluate the 12 A. macrocephala local varieties'seed viability and measure their germination rate.</p><p><b>RESULT</b>Seed viability of A. macrocephala using TTC staining ranked the first compared to that of other three methods. Seed viability was significantly related with germination rate using TTC method. Their correlation coefficient reached 0.915 and regression equation was also found out between seed viability (X) and germination rate (Y), which was Y = -0.083 4 + 0.995 4X.</p><p><b>CONCLUSION</b>TTC staining was the optimal method to determine A. macrocephala seed vitality. Furthermore, seed viability was significant related with germination rate of A. macrocephala.</p>
