A Study of Distribution Status and Conservation Method in Endemic Genus of Early Spring Flowers, Ixiolirion Fischer ex Herbert in Xinjiang
摘要
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.关键词
