Abstract: 【Objective】 Our aims are to conserve and develop endemic genus of early spring flowers, Ixiolirion(Fisch.)Herb. resource in Xinjiang.【Method】 By consulting digital specimen and relevant phylographic analysis, comparing the publishing process, geographical distribution, and indoor germination experiment, the seed characteristics and germination traits of I. tataricum, were studied.【Result】 Seed characteristics showed the fresh, matured seed of I. tataricum had morphophysiological dormancy(MPD), its seed germination was very sensitive to light, temperature and each other's interaction; The germination rate of seeds in the whole dark condition was significantly higher than that in the light condition, the seed germination rate in the low temperature condition(15/5℃) was higher than that in the other variable temperature condition, and the seed germination rate was the highest in the whole dark condition at constant temperature(14℃).【Conclusion】 Seeds of I. tataricum germinate in early spring, and their morphophysiological dormancy can be broken by low temperature stratification.

Key words: Ixiolirion Fischer ex Herbert, endemic genus, protection and development
