华北驼绒藜种子的寿命及其采收贮藏

摘要

The longevity of seed is the timeline that seed can maintain vitality. Research has been done on the Ceratoides arborescens seeds' longevity and the results showed that the Ceratoides arborescens seeds enter into germination climax in 48 h (3 days) under 25 ℃ isothermal and sufficient soil water conditions. The germination is fast and concentrative, full seedling can be reached in 4-5 days under the field sowing condition. The Ceratoides arborescens seeds' longevity can last more than 3 years under the general inventory conditions.%种子的寿命是指种子生命力在一定环境条件下能保持的期限。对华北驼绒藜的寿命进行了探索性试验，试验结果表明，华北驼绒藜的种子在25℃恒温水分满足的条件下，48h（第3天）即可进入发芽高潮。发芽的特点是快而集中，田间播种4-5d即可出全苗；华北驼绒藜的种子在一般库存条件下，可达3年以上。
