种子是种子植物所特有的繁殖器官,它使植物得以传种接代,生生不息。然而种子本身并不是“长生不老”的,它与动物一样,都有一定的寿命,贮藏时容易变质和受虫害,种子的性状也非一成不变,尤其是花费大量的人力物力,精心培育而成的。有些良种遗传性状很不稳定,第二,三代便退化了。能不能在实验室里大量培养出遗传性状稳定,品质优良,便于保管的种子呢?现在由于生物工程的发展, Seeds are the unique reproductive organs of seed plants, which allow plants to be passed on from generation to generation. However, the seeds themselves are not “immortalized”. Like animals, they have a certain life span. They are easily spoiled and pest when stored, and their traits are not constant. In particular, it takes a lot of manpower and resources to nurture . Some elite genetic traits are unstable, the second, three generations will be degenerated. Can a large number of laboratories in the development of a stable genetic trait, good quality, easy to keep the seeds it? Now due to the development of bio-engineering,
