摘　　要：针对从吉林引进的钙果在小兴安岭伊春地区的栽培试验,通过分析叶片表形特征,对钙果在高寒地区的表形多样性表现进行探讨,为优选、改良寒地浆果类品种及开发利用提供技术支持。本文采用露地栽培和塑料大棚栽培两种设计,结合叶长、叶宽和叶面积等调查数据,对钙果叶片的比叶面积、遗传变异系数和叶片干物质含量等指标进行分析。结果表明,定植后的钙果叶片表形性状变异幅度为21.87%~34.44%,各品系均表现出较为丰富的遗传变异特征,这与环境因子的差异有直接关系。在不同立地条件下,不同品系表现出了不同的遗传程度,表现最为明显的是钙果4号品系。结论:在引进伊春地区后,钙果不同品系间遗传丰富度差异确实存在;各品系表形特征产生的差异性均取决于环境因子;而各品系遗传活跃度相近也证明了钙果品系内遗传性状相对稳定。In this paper,Cerasus humilis introduced from Jilin Province was cultivated in Yichun area of Xiaoxing’an Mountains.By analyzing leaf surface characteristics,the phenotypic diversity of Cerasus humilis in alpine regions was discussed,which provided technical support for the optimization and improvement of berry varieties in cold region and their development and utilization.The experimental sample plots were established by two designs of land cultivation and plastic greenhouse cultivation respectively.The leaf area,genetic variation coefficient and dry matter content of the leaves were analyzed by combining with the data of leaf length,leaf width and leaf area.Results showed that:the variation range of phenotypic traits of leaves ranged from^21.87%to 34.44%,and all strains showed abundant genetic variation characteristics,which was directly related to the differences of environmental factors.Different strains showed different degree of genetic activity under different site conditions,and the most obvious one was No.4.After the introduction into Yichun area,the differences of genetic richness between different strains of Cerasus humilis did exist and the differences in the phenotypic characteristics were all from environmental factors.The similarity of genetic activity among the strains also proved that the genetic characters in the Cerasus humilis strains were relatively stable.
