Abstract:: Eight Xinjiang wild rose seeds were used as materials to investigate the effect of seed-coat thickness and low-temperature stratification on Xinjiang wild rose seeds under introduction conditions by low-temperature stratification treatment and seed polishing.The results showed that with a seed-coat thickness of 0.408-0.665 mm，seeds with a germination rate>50% were Rosa beggeriana Schrenk，Rosa laxa Retz.，Rosa ilicnsis and Rosa platyacantha Schrenk in a descending order (germination rate，87.17%，72.17%，75.44% and 68.97%，respectively).Compared with the seed polishing of these four rose seeds，no obvious differences were detected.With normal seed-coat thickness of rose seeds (>0.665 mm)，the germination rate of Rosa oxyacantha M.Bieb.，Rosa acicularis Lindl.，Rosa albertii Reg.and Rosa spinosissima L.var.altaica was relatively low，with Rosa spinosissima L.var.altaica showing a germination rate of 0.00%.Seed polishing increased the germination rate of these four rose seeds in different degrees.The seed germination energy of Rosa beggeriana Schrenk，Rosa ilicnsis，Rosa laxa Retz.and Rosa platyacantha Schrenk were basically concentrated in 7—9 days after low-temperature stratification treatment.
