摘　　要：野蔷薇的种子低温砂藏30 d才开始发芽,然后再需50 d时间才能结束发芽,发芽率为75%左右。酸处理、酸蚀裂口处理可缩短种子低温砂藏时间和发芽时间;通过清水分级可剔除劣质种子,提高种子质量的一致性,从而提高发芽率和发芽整齐度。将野蔷薇种子用盐水分级,剔除劣质种子,然后将分级种子用浓盐酸处理20 min,制成酸蚀种子,再经裂口处理,制成分级酸蚀裂口种子,则处理种子低温层积13 d开始发芽,发芽时间缩短为16 d,发芽率提高到90%以上。The germination percentage was about 75% for a batch of Rosa mutiflora seeds, which started to 30 days and nearly 50 days duration of germination straticafied at low tempreture （0 -4℃） , The starting time and the duration of germinatiom could be shortmened if seeds was treated with HC1 and cracked. On the other hand, germination percentage and germination tidiness could be improved if seeds was sorted with water. According to these results, firstly seeds of Rosa multiflora was sorted with water, then treated 20 minutes with HCl and cracked and straticafied successively. As a result, only 13 days starting time and 16 days duration of germination was needed for seeds to germinate, and germination percentage could be improved to above 90%.
