美国克姆苏大学园艺学家克恩研究成功了胚珠培养技术。此技术能加快无籽葡萄新品种的繁育,提高产量,增加了培育无籽葡萄植株的可能性。目前培育无籽葡萄新品种是采用成熟的母体与无籽植株父本花粉授粉获得的。由于这个方法有80%的子代产生种子,故效率较低,在获得的无籽葡萄品种中,胚珠在生长早期就败育。克恩尝试使用胚珠培养技术来防止胚珠 Kern University horticulturalist Kern successful study of ovule culture techniques. This technology can speed up the breeding of new seedless grapes, increase yield, increase the possibility of cultivating seedless grape plants. At present, the cultivation of new seedless grapes is based on pollination of mature parent and seedless male parent pollen. Since 80% of the progeny in this method produce seeds, they are inefficient, and in the seedless grape varieties obtained, the ovules are aborted in the early stages of growth. Kern attempts to use ovule culture techniques to prevent ovules
