Picea wilsonii Mast.%seed%germination traits
以青杄云杉为材料，观测种子发芽性状，结果表明：不同植株种子发芽率变动在86％～94％之间，均值为90％；发芽势变动在57％～73％之间，均值为65％，发芽率的差异由株间遗传性不同所致。种子具有发芽启动快、整齐的特点，发芽观测时间以14 d为宜。
以青杄雲杉為材料，觀測種子髮芽性狀，結果錶明：不同植株種子髮芽率變動在86％～94％之間，均值為90％；髮芽勢變動在57％～73％之間，均值為65％，髮芽率的差異由株間遺傳性不同所緻。種子具有髮芽啟動快、整齊的特點，髮芽觀測時間以14 d為宜。
이청천운삼위재료，관측충자발아성상，결과표명：불동식주충자발아솔변동재86％～94％지간，균치위90％；발아세변동재57％～73％지간，균치위65％，발아솔적차이유주간유전성불동소치。충자구유발아계동쾌、정제적특점，발아관측시간이14 d위의。
Picea wilsonii Mast.was taken as materials to observe germination traits of seed , the results showed that seed germination rate of different plant was between 86%~94%, mean value was 90%;germinating potential was between 57%~73%, mean value was 65%, the differences of germination rate caused by the genetic of differentce plants .The charac-teristics of seed sprouting were fast and neat , and the suitable observation time was 14 d.
