Abstract: In order to studyStipa glareosa seed germination characteristics and mechanism of dormancy, seed germination and experiment ecological methods was used to study the effects of different light, cut through the kind of and removal of different proportions of skin (fruit) onStipa glareosa endosperm germination and analog field conditions different burial depths seedling emergence. The results showed that:Stipa glareosa germination rate under dark conditions was significantly higher than light conditions; removal of 75% of the endosperm, Stipa glareosa germination was the fastest; different burial depth when buried of 0.5 cm in shallow sand seed germination andStipa glareosa was the highest rate of seedling emergence but dormancy rate was the lowest; sand burial depth of more than 2 cm after,Stipa glareosa seed germination, seedling emergence rate and sand burial depth was negatively correlated with sand burial depth dormancy rate increases.Stipa glareosa seed was the germination type latent dark conditions. Artificial seedingStipa glareosa seeds should be 0.5-2 cm depth is appropriate.
