Summary:To establish the seed quality grading standard of artificial tuber of Pinellia ternata. Hundred-grain weight, moisture content, germination rate, viability, single-grain diameter, purity and visual form of mature artificial tuber seed from tissue culture of P. ternate were determined. The key indicator and reference indicators for artificial tubers quality grading were defined statistically by SPSS analysis. Germination rate and viability were the primary indicators, hundred-grain weight, moisture content and purity were important reference indicators. The quality of each grade should reach the following requirements: for first grade, hundred-grain weight > 10 g, moisture content > 70%-80% , germination rate > 80%, viability > 85%, single-grain diameter > 0.7 cm, purity > 80%; for second grade, hundred-grain weight 8-10 g, moisture content > 70%-80%, germination rate 60%-80%, viability 70%-85%, single-grain diameter 0.3-0.7 cm, purity 75%-80%; moisture content > 70%-80%, and the others don't reach second grade was the third grade.
