Effect of Stratification on Seed Germination of Amomum tsaoko
In this research,we studied the effect of temperature and light,constant temperature stratification,alternating temperature stratification and stratification after dehydration on seed germination of Amomum tsaoko.The results showed that the viability of freshly seed was significantly greater than the germination rate,which indicated that there was obvious dormancy phenomenon in freshly collected Amomum tsaoko seeds.Both constant temperature stratification and alternating temperature stratification could promote seed dormancy release of Amomum tsaoko,but the treatment effect of warm stratification was the best.After warm stratification for 90 days,the germination percentage of Amomum tsaoko seeds was up to 82.0％.Seed moisture content of Amomum tsaoko could significantly influence seed germination,when seed moisture content was lower than 15％,seed germination rate decreased significantly.
