人类生活离不开种子,种子养活了全人类。随着生物技术的发展,科学家们已研制成功各种人工种子;人工种子的诞生,又向人类展示了十分诱人的前景。 人工种子是模仿天然种子的结构研制而成的。它由人工种皮、人工胚乳和培养物(胚状体、不定芽、毛状根、腋芽、小鳞茎等)三部分组成。人工种皮也像天然种子一样由内、外两层构成,是由能与植物组织密切溶合的高分子化合物(如海藻酸钠、明胶等) Human life is inseparable from the seeds, the seeds feed all mankind. With the development of biotechnology, scientists have successfully developed a variety of artificial seeds; the birth of artificial seeds, in turn, has shown to humans a very attractive prospect. Artificial seeds are made from a structure that mimics natural seeds. It consists of artificial seed coat, artificial endosperm and culture (embryoid body, adventitious buds, hairy roots, axillary buds, bulbs, etc.) composed of three parts. Artificial seed coat also like the natural seed from the inside and outside the two layers by the close integration of plant tissues with high molecular compounds (such as sodium alginate, gelatin, etc.)
