摘　　要：本试验研究超干马尾松等种子在密封室温状态下贮藏 1a后其生活力和生理生化特性的变化 ,结果表明 :杉木种子在含水率为 4%～ 5 % ,马尾松种子含水率为 5 % ,木麻黄种子为 1%时 ,种子保持较高活力 ,说明超干处理有利于马尾松。Ultra\|drying Chinese\|fir, pine and Casuarina equisetifolia seeds had higher vigor after one\|year\|storage in ambient temperature. When Chinese\|fir seed MC was between 4 percent and 5 percent , pine seeds MC was 5 percent and Casuarina equisetifolia seeds MC was 1 percent ,its higher viability and vigor could be retained, its cell membrane integrity remained well and the activity of dehydrogenase, α\|Amylase and respiration intensity were highest. So ultra\|dry could improve the storability of Chinese\|fir, pine and Casuarina equisetifolia seeds.
