| 摘 要： | 研究分析了华北平原11种植物种子萌发所需要的生物学零度和积温,结果表明:与其原产地年均气温比较,由于长期的适应,各植物的生物学零点和原产地的平均气温存在明显的正相关关系;种子萌发的积温和种子萌发的生物学零度之间存在显著地负相关关系。

| Abstract: | Temperature is an important environmental factor influencing seed germination. In this study, the accumulated temperature and biological zero for germination of 6 Poaceae species and 5 fabaceae spe- cies of North China Plain were analyzed. The results showed that compared with its average annual tem- perature of the origin, due to the long-term adaptation, there were most significant positive correlations between the biological zeros of the plant and the average temperature of the origin ; there were most signif- icant negative correlations between the accumulated temperature and biological zero of seed germination. |
