所谓人工种子是经人工包裹并能在适宜条件下发芽出苗的单个体细胞胚。它是通过组织培养,将植物的体细胞诱导成在形态和生理上均与合子胚相似的体细胞胚,然后将其包埋于有一定营养成分和保护功能的介质中,组成了便于播种的类似种子的单位。人工种子优点:①繁殖速度快;②体积小,贮藏运输方便且有利于机械化播种;③与试管苗相比成本较低;④能保持并多年利用杂种优势;⑤与常规育种相结合可大大缩短育种年限;⑥节约大量留种
The so-called artificial seeds are artificially wrapped and can germinate under appropriate conditions single somatic embryos. It is through tissue culture, plant somatic cells induced to morphologically and physiologically are similar to zygotic embryos, and then embedding it in a medium of certain nutrients and protective functions, composed of easy sowing Seed-like unit. The advantages of artificial seeds: ① breeding speed; ② small size, easy storage and transportation and is conducive to mechanized seeding; ③ lower cost compared with test tube seedlings; ④ can maintain and use heterosis for many years; ⑤ combined with conventional breeding can be greatly reduced Breeding years; ⑥ save a lot of stay species
