Abstract:
To seek method of breaking seed dormancy of different kinds of wild tulips and appropriate temperature for germination to improve their germination quality outside their habitat，the influences of germination temperature，different concentrations of GA3 and stratification time on the Final Germination Percentage (FGP) and Mean Germination Time (MGT) of T.iliensis（2011，2013）and T.sinkiangensis（2013） were studied.The results showed that all these tulips seeds had dormancy，T.sinkiangensis had shallower dormancy than T.iliensis and their germination conditions were inconsistent，germination result of T.iliensis seeds collected in different years had remarkable differences，seeds gathered in 2011 was much better than that of 2013.The most suitable temperature for seeds of T.sinkiangensis and T.iliensis to germinate was 10℃.Different concentration of GA3 and stratification time had significant influences on FGP and MGT values of different kinds of tulips seeds，500 mg/L was the suitable concentration for T.iliensis seeds collected in 2013，300 mg/L was the suitable concentration for T.iliensis seeds collected in 2013,T.sinkiangensis seeds needed no exogenous GA3 to germinate；seeds of T.iliensis (2011,2013) needed stratification of 21 days to break dormancy，T.sinkiangensis seeds need no stratification to reach the germination rate of 95%.In conclusion，GA3 and stratification treatment had no additive effect on germination of tulip seeds were used and stratification treatment could be substituted by GA3 treatment.
