| 摘 要： | 通过生理、生化途径对杉木三个种源种子活力的初步研究表明：发芽率、幼根平均长度、发芽指数、发芽高峰值、活力指数等生理发芽指标间紧密相关；在生化指标中，过氧化物酶活性与种子日平均发芽的率的波动呈规律性变化；电导率亦随种子活力的高低而波动。

| Abstract: | Research was made on the vitality of China fir seeds from three provenaces by physiological and biochamical means.The results showed that physiological germination indexes such as germination percentage,germination index,germinative peak value and vitality index were closely interrelated.As the biochemical indexes were concerned,the vatality of peroxidase and the fluctuation of daily average germination percentage displayed a regular change.Electro-conductivity also undulated along with high or low seed vatality. |
