| The objective of this study is to promote germination for mass cultivation of Adenophora triphylla. After the seed soaking for I day in BA and $GA_3$ solution, seed germination was effectively promoted in the treatment of 500mg/L $GA_3$ and the highest germination rate was 94%.The average germination days were 1.5days earlier than those of non-treated seeds. In a chemicals treatment, seed germination rate was 54% in 1% $KNO_3$ treatment but KOH treatment was no significantly effected. The durations of chilling treatment for breaking of dormancy were longer than 2weeks. The optimal temperature for germination was $25^{circ}C$. The promotion of seed germination is presumed to be due to the breaking of dormancy by $GA_3$, chilling treatment rather than seed coat maceration by KOH or $KNO_3$ treatments. |
