【摘要】 了解不同东北刺人参种群种实性状变异规律，为良种选育提供依据。以长白朝鲜族自治县泡子涯小沟、冷沟子林场、十五道沟，临江市东小山林场，集安市大顶子村5个不同东北刺人参种群为研究对象，对果柄长、果柄直径、果实纵径、果实横径、果形系数、单果质量、种子长、种子宽、种形系数、种子千粒重10个种实表型性状进行测定及统计分析。结果表明：东北刺人参种群间种实性状变异系数均值(28.3%)大于种群内(20.63%),变异主要来源于种群间；相关性分析结果显示，东北刺人参种实有10对性状的相关性不显著，其余每对种实性状均呈现出显著或极显著相关性；主成分分析结果显示，果实横径、果实纵径、单果质量、种子长和种子千粒重代表了东北刺人参种实性状的绝大部分信息。综合评价可知，长白朝鲜族自治县十五道沟东北刺人参种群的种实性状最优。更多还原

【Abstract】 To understand the variation rules of seed and fruit traits of Oplopanax elatus in different populations, with the aim of providing the basis for breeding of high quality varieties.Five different populations of Oplopanax elatus in the Paoziya Xiaogou of Changbai Korean Autonomous County, Lenggouzi Forest Farm, East Hill Forest Farm of Linjiang City, Fifteen Daogou and Ji’an Dadingzi Village were taken as research objects.The peduncle length, peduncle diameter, fruit longitudinal diameter, fruit transverse diameter, fruit type coefficient, single fruit weight, seed length, seed width, seed type coefficient and 1 000-grain weight of seed were measured and analyzed statistically.The results showed that the mean coefficient of variation of seed-fruit traits among populations(28.3%) was larger than that within populations(20.63%),and the variation of seed-fruit traits was mainly from inter populations.Correlation analysis showed that 10 pairs of seed-fruit traits were not significantly correlated each other, and the rest showed significant or extremely significant correlation each other.The results of principal component analysis showed that fruit transverse diameter, fruit longitudinal diameter, single fruit weight, seed length and 1 000-grain weight of seed represented most of the information of seed-fruit traits of Oplopanax elatus.Comprehensive evaluation results showed that the traits of seed and fruit of Oplopanax elatus population in the Fifteen Daogou of Changbai Korean Autonomous County were the best.更多还原
