摘要(Abstract):

探讨不同品系黄芩表型性状的差异与相关性。比较了14个黄芩品系的10个地上部性状和6个根部性状,并运用SPSS 17.0统计软件对数据进行方差分析、相关分析和主成分分析。结果表明不同品系黄芩的表型性状变异十分丰富,多样本方差分析显示F为3.169~71.58,差异显著,参比品系中性状表现最优良的是15号。相关分析显示,除侧根数、根粗、根长外,其余性状之间均存在显著相关性,芦头直径与根鲜重存在极显著性相关,相关系数高达0.877。主成分分析表明黄芩单株整体产量和根粗可作为优良品种选育的综合参考指标。不同品系黄芩的主要表型性状存在显著差异及相关性,可为黄芩品系的性状特征区分、评价及优良品种选育提供理论依据。
To research the differences and correlation between Scutellaria baicalensis about phenotypic traits of different strains,10 aboveground traits and 6 root traits of S. baicalensis in two-year-transplanted plants from 14 different strains were compared respectively,and the SPSS 17. 0 statistical software was used for data analysis. It showed that phenotypic traits variation of different S. baicalensis strains was rich and the F value ranged from 3. 169 to 71. 58. The difference was significant between each other and germplasm 15 performs the most outstanding characters. Correlation analysis showed that there existed a significant correlation between the characters except for lateral root number,root diameter and length. The correlation coefficient between the fresh weight of root and the reed head diameter was up to 0. 877. Principal component analysis showed that the average of overall yield per plant and root diameter could be used as the comprehensive reference index for germplasm evaluation. The differences and correlations in phenotypic traits of different S.baicalensis strains,provide theoretical basis for distinguishing germplasm and breeding good varieties of S. baicalensis.
