吉林东部不同东北刺人参种群种实表型性状变异规律
Phenotypic Trait Variations of Seed and Fruit of Different Oplopanax elatus Populations in Eastern Jilin Province
摘要
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.关键词
