摘要
以1 a生枝的树皮为材料,利用酯酶同工酶技术对青岛市19个樱花品种进行亲缘关系鉴定和品种分类研究。结果表明:19个樱花品种的酯酶同工酶酶谱共有12条酶带,其中P7为基本酶带,活性强,为大部分品种所具有,其他谱带在品种间有差异。根据酶谱进行UPGMA聚类分析,得出反映各品种间亲缘关系的树状聚类图。聚类结果以花的重瓣性将19个樱花品种分为两大类群,根据种源、花色和枝姿的不同又分为不同的亚类群和类,其结果与传统分类学结果具有一致性,表明种源、重瓣性、花色和枝姿都可作为樱花品种分类的重要指标,有较好的稳定性。
Phylogenetic relationship identification and classification of 19 Cerasus cultivars in Qingdao were studied by esterase isozyme technology by using of the bark of annual and branches as meterials. There were 12 esterase isozyme bands for 19 Cerasus cultivars. P7 was basic band, which had high activity and was owned for most of the cultivars. Other bands were different between all cultivars. A dendrogram showing genetic relationships was constructed through an UPGMA （Unweighted Pair-group Method Arithmetic Average） method. 19 Cerasus cultivars were divided into two groups based on the charicteristics of double petals. Each group was divided into several subgroups and kinds based on the provenance, color of flowers and posture of branches. Esterase isozyme technology provided the same results of classification on Cerasus cultivars to the traditional method. Provenance, the charicteristics of double petals, color of flowers and posture of branches were the important index for classification of Cerasus cultivars, which had high stability.
