摘要: 以5 个砧木(平邑甜茶、八棱海棠、楸子、新疆野苹果、东北山荆子)与富士苹果嫁接组
合的2 年生幼树为试材,采用盆栽方法和碳氮双标记示踪技术,研究了5 个组合的生长特性及其对氮素
荆子组合生长量最小。富士/平邑甜茶组合对15N 的利用率最高,富士/楸子组合最低。15N 和13C 均主要分
配在叶中,其次是1 年生茎,最少的为2 年生茎;富士/东北山荆子组合叶中的15N 和13C 分配率最高,
富士/平邑甜茶组合根中的15N 和13C 分配率最高。从碳氮营养角度来看,富士苹果以平邑甜茶作砧木最

Abstract: Five types of two-year-old apple rootstock-scion combinations[scion:Malus × domestica
Borkh.‘Red Fuji’;rootsocks:M. hupehensis(Pamp.)Rehd. var. pinyiensis,M. micromalus Makino,
M. prunifolia(Willd)Borkh.,M. sievesii(Ledeb.)Roemer,M. baccata Borkh.,recpectively]were used
to study the growth and the characteristics of distribution and utilization of 15N and 13C. The results were as
follows:The biomass of‘Red Fuji’/ M. hupehensis Rehd. was the largest,while that of M. domestica
Borkh.‘Red Fuji’/ M. baccata Borkh. was the least. The 15N utilization ratio of ‘Red Fuji’/ M.
hupehensis Rehd. was the largest,while‘Red Fuji’/ M. prunifolia(Willd)Borkh. was the least. The 15N
and 13C distribution ratio of leaves was the highest,while annual stems was less than leaves,and the
biennial stems was the least. The 15N and 13C distribution ratio in leaves of ‘Red Fuji’/ M. baccata Borkh.
were the largest,while those in the roots of ‘Red Fuji’/ M. hupehensis Rehd. were the largest. Therefore,
‘Red Fuji’/ M. hupehensis Rehd. was the best considering with carbon and nitrogen nutrition.
