Abstract：By collecting and investigating the germplasm resources of Cynanchum paniculatum in Shan-dong Province , the seed neatness , thousand seed weight , moisture content , germination rate and viability were measured, and the seed quality classification standard was preliminarily established .The results showed that the neatness of good Cynanchum paniculatum seed was above 90%,the thousand seed weight was above 5.0 g,the moisture content was below 9.0%,and the germination rate was above 90%.The TTC method could be used for determination of seed viability of Cynanchum paniculatum and had better effect when the TTC concen-tration was 0.5%after soaking for 24 hours and staining for 4 hours.And the average seed viability was about 90%.The seed quality of Cynanchum paniculatum was preliminarily classified into three grades .
