摘　　要：以6年生单主干形‘燕红’和‘沙红’2个桃树品种为试材,采用Elx800酶标仪进行酶联免疫吸附测定法,研究了桃树不同骨干枝角度对成熟果实、树皮、枝皮以及枝条内源激素含量的影响,以期探索出不同骨干枝角度内源激素分布情况,为生产上提供理论指导。结果表明:骨干枝倾斜45°的成熟果实、树皮、枝皮以及枝条中赤霉素(GA)和生长素(IAA)含量显著高于其它处理,玉米素核苷(ZR)和脱落酸(ABA)含量则是骨干枝角度倾斜45°显著低于其它处理;ZR/GA、ZR/IAA、ABA/GA、ABA/IAA均是骨干枝倾斜45°最大,其次是骨干枝倾斜30°,最低的为对照(直立);不同桃树品种成熟果实、树皮、枝皮和枝条中内源激素含量存在差异。The 6-year-old single main-shaped‘Yanhong’and‘Shahong’two peach species were used as test materials.Enzyme-linked immunosorbent assay using the Elx800 microplate reader,to study on the contents of endogenous hormone in mature fruits,bark,branches and shoots of peach trees for the different angle of backbone branches,in order to explore the distribution of endogenous hormones at different angles of the backbone,to provide theoretical guidance for production.The results showed that the contents of gibberellin(GA)and auxin(IAA)in the backbone branches angle of 45°were significantly higher than the other two treatments in mature fruits,bark,branches and shoots,the contents of zeatin nucleoside(ZR)and abscisic acid(ABA)in the backbone branches angle of 45°were significantly lower than the other two treatments;further research indicated that ZR/GA,ZR/IAA,ABA/GA,ABA/IAA were the largest in the backbone branches angle of 45°,the second was the backbone branches angle of 30°,the lowest was the control(the backbone branches angle of 0°);the content of endogenous hormone had a difference for mature fruits,bark,branches and shoots in the different varieties of peach.
