福建省农科院葡萄品种选育组在直接从日本引进的纯正的伊豆锦品种树上进行无核化处理,无核果粒重一般10～13克,最大16克,果粒已达有核果巨峰那样巨大粒级标准,且裂果少、着粒牢固、着色均匀、提前成熟,达到了可供生产实用的要求,标志了品种引进及处理技术上的成功。本葡萄选育组1992年仅能在较弱的树体上进行无核化处理,随后则有条件在养分较充裕的强壮树上处理试验以获更佳效果(果粒可更大),以此推进无核化
Fujian Provincial Academy of Agricultural Grape Varieties breeding groups in the direct introduction of Japan from Japan Genuine Izu Kam tree species of non-nuclear treatment, non-core fruit weight is generally 10 to 13 grams, the largest 16 grams, the fruit has reached a nuclear fruit Kyoho That huge size standards, and less cracking, grain solid, uniform coloring, mature in advance to meet the practical requirements for production, marking the species introduction and processing of technical success. The grafting group of the grapes could only be denuclearized on weaker trees in 1992, and subsequently the conditions were better tested on stronger trees with stronger nutrients (fruit size may be larger) This promotes denuclearization
