| 为选育黑果枸杞优树植株，以人工种植的黑果枸杞为研究对象，在大面积实地调查的基础上，根据黑果枸杞树形、枝条、花、叶、果实、抗病虫害状况等30个优树表型，经过2 a表型稳定性的观测，初步选出表型性状优良的黑果枸杞100株，采其果实。以高花青素为目标，根据药理作用相似相辅的原理，选择多酚、黄酮为辅助指标，利用各性状的均值、标准差和极差建立黑果枸杞优树综合评分法，复选出14株优等植株。指标间相关性分析表明花青素与黄酮含量呈极显著正相关（p＜0.01）；花青素与多酚含量呈显著正相关（p＜0.05）；黄酮与多酚含量呈弱相关。研究结果进一步说明花青素、黄酮、多酚作为优树选择指标的合理性，为建立黑果枸杞无性系苗圃、优树再复选提供了筛选依据。 |

| In order to explore the superior tree plants of Lyciumruthenicum and search for excellent varieties, taking the artificially planted Lyciumruthenicum as the research object, on the basis of large-scale field investigation, according to 30 superior tree phenotypes of Lyciumruthenicum, such as tree shape, branch, flower, leaf, fruit, disease resistance, and insect pest status, 100 Lyciumruthenicum plants with excellent phenotypic characteristics were preliminarily selected and their fruits were collected after 2-year observation of stability of phenotype. Taking high anthocyanins as the target, according to the principle of pharmacological action similarity, polyphenols and flavonoids were selected as auxiliary indexes, and the comprehensive scoring method of superior trees of Lyciumruthenicum was established by using the mean, standard deviation, and range of each character, and 14 superior plants were selected. In the correlation analysis, it was found that anthocyanins and flavonoids content were significantly positively correlated (p<0.01); anthocyanins and polyphenols content were significantly positively correlated (p<0.05); flavonoids and polyphenols content were weakly correlated, which further explained the rationality of anthocyanins, flavonoids, and polyphenols as the selection index of superior trees, and provided the basis for the next step to establish the clone nursery and superior tree selection according to support. |
