摘　　要：研究引进酸浆和本地野生酸浆在小兴安岭高寒地区统一栽植后的遗传变异表现及遗传多样性,为杂交后代性状早期选择提供依据。对引进酸浆品种及小兴安岭岭野生挂金灯酸浆2个品种叶片性状的表型特征、变异程度等相关数据进行分析。通过对2个酸浆品种叶片形态特征指数进行系统分析证明,虽然2个品种间叶片大小存在着明显差异,但本身叶型指数等指标均分布于组内合理区间内;通过对干物质含量(LDMC)、比叶面积(SLA)及变异系数(C V)3项指标进行统计分析说明,引进酸浆品种因叶片更大,所以在能量累积方面更占优势;遗传系数计算说明,引进酸浆品种组内遗传性状稳定,遗传系数较小。挂金灯酸浆品种虽为本地野生品种,但其遗传系数较高,说明在不同栽植条件下更容易受环境饰变影响,性状并不稳定。In order to study the genetic variation and genetic diversity of introduced and local wild Alkekengi officinarum after unified planting in the Xian Hinggan Ling alpine region,and provide a basis for the early selection of traits of hybrid offspring,the phenotypic characteristics,variation degree and other related data of leaf traits of the two introduced Alkekengi officinarum varieties and the two wild varieties of Physalis alkekengi L.var.francheti in Xiao Hinggan Ling were analyzed.The results showed that:through the systematic analysis of the leaf shape characteristic indexes of the two varieties of Alkekengi officinarum,it was proved that although there were significant differences in leaf size between the two varieties,the leaf shape indexes of the two varieties themselves were distributed within a reasonable range within the group.Through the statistical analysis of three indicators,namely,leaf dry matter content(LDMC),specific leaf area(SLA)and coefficient of variation(Cv),it was shown that the introduced varieties of Alkekengi officinarum had more advantages in energy accumulation due to their larger leaves.The calculation of genetic coefficient showed that the genetic characteristics of the introduced varieties of Alkekengi officinarum were stable and the genetic coefficient was small.Although the variety of Physalis alkekengi L.var.francheti was a local wild variety,its genetic coefficient was high,indicating that it was more vulnerable to environmental modification under different planting conditions,and its character was not stable.
