怎样才能使有核葡萄品种在不改变其品种特性的基础上,人为控制使其成为无核葡萄,现已引起国内外专家们关注。在日本利用赤霉素处理有核葡萄诱发无核葡萄已获得成功,但我国在这方面的研究比较少,尚未见报道。笔者在1991年5月下旬和6月上旬利用500ppm赤霉素对巨峰、先锋、乍娜、马奶4个葡萄品种进行试验,每个品种处理10穗,以用水处理为对照,在盛花期前10天浸穗一次。试验结果表明,经过赤霉素处理,巨峰、先锋、乍娜
How to make the nuclear grape varieties without changing the characteristics of their varieties, based on artificial control to become a seedless grape, has attracted the attention of experts at home and abroad. In Japan, the use of GA3 treatment of nuclear grapes induced seedless grapes has been successful, but our research in this area is relatively small, has not been reported. The author used 500ppm gibberellic acid to test 4 grape varieties of Jufeng, Pioneer, Zhana, and Mamma in late May and early June of 1991, each treated 10 spikes with water treatment as the control, 10 days immersion spike once. Test results show that, after gibberellin treatment, Kyoho, Pioneer, Zachary
