摘　要：

贮藏的成熟水曲柳种子经夏越冬播种的结果表明, 贮藏的成熟种子经夏越冬播种可以萌发, 东北地区的播种时间宜在9月之前。用适宜的植物生长调节物质处理可以获得较好的发芽效果, 其中以100 mg·L-1激动素浸种1 d的效果较好。

Abstract:

The stored mature seeds of Fraxinus mandshurica were sowed last summer as materials in the research on germination responses of overwintering pregermination on field. The results showed that the stored mature seeds sowed last summer could germinate with the overwintering treatment. In northeast China, the appropriate sowing time was before September. The germination percentage increased with different treatments of plant growth substances, and the treatment of 100 mg·L^-1 kinetin for 1 day had better effects on the germination of Fraxinus mandshurica seeds.

Key words: Fraxinus mandshurica Rupr.; seeds; last summer sowing; germination
