摘要
1988～1991年对葡萄6个早熟品种和7个四倍体品种进行种子胚培养,成苗率分别达到40%～71%和52%～89%,与常规播种相比,成苗率提高两倍以上。早熟品种和四倍体品种在浆果成熟期接种培养的效果明显地优于花后45天接种者,低温和切喙处理有效地促进了早熟和四倍体品种胚的萌发,并提高了成苗率,提出了一套早熟和四倍体葡萄品种胚培养的有效措施。
The percentage of planflets obtained from in-seed embryo culture of six early ripening grape eultivars and seven tetraploidy grape cultivars were 40%～71% and 52%～89%, respectively, which were more than three times higher than those from both conventional seed plantings. For eady ripening grape eultivars and tetraploidy grape cultivars embryo culturing at mature stage of fruit got significantly better results than culturing at 45 days after anthesis. Cold treatment and beak cut for cultured seeds raised the percentages of embryo germination and plant formation. An effcient approach of embryo culture for early ripening grape cultivars and tetraploidy grape cultivars was made.
