This study aimed at analyzing the effect of genotype (G), environment (E) and their interactions (G x E) on the major bioactive components of 2-year licorice (Glycyrrhiza uralensis) population, in order to provide a theoretical basis for the licorice breeding with high content of bioactive components and quality improvement.
Four genotype licorice populations were transplanted under four different environments by using complete randomized block design with three replicates, and four major bioactive components, including glycyrrhizin (GL), total saponins (TS), liquiritin (LQ) and total flavonoids (TF) were determined by UV and by HPLC.
The major bioactive components of licorice were influenced by genotype and environment, and the genotype had more effect on all of the bioactive components. The contents of GL and LQ were codetermined by genotype and environment factors.
There exist different selective effects on different growth region for quality breeding in cultivated population of licorice.
本研究旨在分析基因型（G）、环境（E）及其互作（G×E）对两年生甘草（Glycyrrhiza uralensis）群体主要生物活性成分的影响，为培育生物活性成分含量高的甘草品种及品质改良提供理论依据。
采用完全随机区组设计，将4个基因型甘草群体移栽至4种不同环境下，重复3次，采用紫外分光光度法和高效液相色谱法测定甘草酸（GL）、总皂苷（TS）、甘草苷（LQ）和总黄酮（TF）4种主要生物活性成分的含量。
甘草主要生物活性成分受基因型和环境影响，其中基因型对所有生物活性成分的影响更大。GL和LQ的含量由基因型和环境因素共同决定。
甘草栽培群体品质育种在不同生长区域存在不同的选择效应。
