种子寿命是种子生活力在一定环境条件下所能保持的最长期限。蔬菜种子的寿命越长,它在生产上可利用的年限越长,这不仅减少了良种繁殖耗费的人力、物力,而且可以减少繁殖代数,避免在播种、去雄授粉、收获等种子生产各环节造成混杂和差错,从而保持种性长久。正确掌握种子生命活动规律,系统了解影响蔬菜种子寿命的因素,采取有效措施,尽最大可能延长其寿命与使用年限,在生产实际中具有重要意义。
Seed life is the longest life expectancy of seeds under certain environmental conditions. The longer the vegetable seed’s longevity, the longer it can be used in production. This not only reduces the manpower and material resources consumed by seed breeding, but also reduces breeding algebra and avoids various steps of seed production such as sowing, deoxynulation and harvesting Cause confusion and error, thus maintaining long-term species. Correctly grasp the rules of seed life activities, systematically understand the factors that affect the life of vegetable seeds, take effective measures to maximize their life expectancy and useful life, in the production of practical significance.
