为了保证农林及园艺生产,人们总要想方设法将种子贮藏好多年。近年来,各国普遍注意种质资源的贮备,尤其是濒危及珍稀植物的保存,更需要研究种子的贮藏问题。植物种子寿星多大量资料表明,许多种子寿命比人的寿命要长的多。据美国加利福尼亚大学哈林顿报道,种子寿命在10年以上的有70多科,700多种;寿命在100年以上的有60多种;500年以上的有20多种。这些种子中的老寿星,虽然跨过了几个世纪,还有一定的生命力。
In order to ensure that agriculture, forestry and horticultural production, people always find ways to store the seeds for many years. In recent years, all countries have generally paid attention to the stock of germplasm resources, especially the preservation of endangered and rare plants, and the need to study the storage of seeds. Lots of information on plant seeds shows that many seeds live longer than people. According to reports from the University of California, Harrington, there are more than 70 families and 700 species with more than 10 years of seed life; more than 60 species have a life expectancy of more than 100 years; and more than 20 species have more than 500 years of history. The oldest of these seeds, although spanning centuries, has some vitality.
