摘　　要：分别取艳红桃树同一株上的芽变枝（样品1）和非芽变枝（样品3）以及芽变枝芽接离体株（样品2）的鲜叶进行了酯酶（EST）同工酶谱带分析。结果：样品1～3具有A1、B1、B2和C2共同谱带。其中，C1为样品3的独有谱带t样品1和样品2均缺失C1谱带．表明芽变源于C1谱带的缺失，样品1和样品3具有很近的亲缘关系，在嫁接无性繁殖条件下样品1和样品2的芽变性状稳定。The fresh leaves of Yanhong peach from homophyletic bud mutation （sample 1） and non-bud mutation （sample 3）, and plant budding in vitro （sample 2） were analyzed by esterase isozyme. The results show that the sample 1, 2 and 3 have common bands of A1, B1, B2 and C2. Band C1 is the special one of the sample 3 and lacking in samplel and 2, which indicates bud mutation originates from loss of C1. Sample 1 and 3 has very close. Properties of bud mutation in sample 1 and 2 are stable under propagate conditions of graiting.
