摘　　要：试验以新采收的红叶黄栌种子为试材,采用不同的贮藏条件和不同的药剂催芽处理,研究有效促进黄栌种子萌发的方法。结果表明:采用-10℃储藏与常温贮藏相比对种子萌发没有效果,而采用4℃沙藏则可明显提高黄栌种子的发芽率;用KNO3溶液浸种处理,可使红叶黄栌种子发芽率明显提高,当KNO3浓度为8%时最高,发芽率为48%。In this test, new harvest C. coggygria var. cinerea seeds were soaked with different medicament dispose and storage conditions to see the effect, the effective ways of promote seed germination of Cotinus coggygria Scop were studied. The result showed that the normal temperature storage and storage of seed germination without effect compared with below ten degrees celsius, and the storage way in the sand can obviously improve C. coggygria var. cinerea seed germination rate. On seeds soaking treatment with 8% potassium nitrate solution, the germination rate was highest, it was 48%.
