青杄云杉不同植株种子发芽性状的观测与分析

Observation and analysis of seed germination traits of different plant of Picea wilsonii Mast.

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。

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.
