嫁接对茶树新梢化学成分的影响

摘要

Grafting with eultivar "Yunaadaye" as stock and tea clones"Wuniuzao" and"Ｚhenong-113" as scio was carried out.Chemical compsition in shoots the combination plants was inveaigated and compared with scion clones trans planted at the same time as grafting did.The results showed that comtents of amino acids and caffeine were increased in com bination plants but tea ployphenols and tea catechins were decreased.%以云南大种为砧木、乌牛早和浙农113为接穗进行嫁接试验，并与同期移栽的乌牛早和淅农113进行化学成分分析比较.结果表明，嫁接对该2品种的化学成分含量均有明显影响，氨基酸和咖啡因含量增加；茶多酚和主要儿茶素类含量减少.
