摘　　要：以鸡树条荚蒾种子为材料,研究其在室内变温条件下沙藏催芽处理的发芽能力,结果表明：在8℃~23℃相对较高温度的变温处理条件下,经历了近4个月的沙藏层积处理,平均发芽率为92%,不发芽种子均因霉烂所致,无空粒、病虫粒等,说明授粉相对充分,没有种实虫害发生。幼苗平均高度为4.75 cm,子叶展开。The germinating ability of sand storage accelerating germination treatment under the varying temperature condition indoors was researched by taking the Viburmum sargentii koehne seeds as material. The result showed that the average germination rate was 92% through sand storage stratification treatment for nearly 4 months under relative higher changing temperature treatment 8℃ ~ 23℃. The seeds which didn＇t bud resulted from rotting. There was no empty,disease and pest grains and so on. It demonstrated that the fertilization was sufficient relatively and had no occurrence of seeds insect attack. The average height of seedlings was 4. 75 cm. The cotyledon unfolded.
