连翘不同果形质量评价

Quality Evaluation of Different Fruit Types of Forsythiae Fructus

目的:探讨连翘的种内变异,明确不同果形连翘的形态特征,质量和产量的差异,为更好的开发、利用和保护连翘种质资源,以及优良品种的选育,奠定了基础。方法:观察不同果形连翘的形态特征,测定其果实长宽及产量,作为划分果形的依据;采用高效液相色谱法对不同果形连翘中化学成分的含量进行了测定,并对其进行综合评价。结果:种内变异的调查,根据连翘果实不同形状进行了分类,分为长角椭圆形、椭圆形、纺锤形、狭长形、圆形等果形;并对不同果形的经济指标和性状进行了评价分析和描述。结果表明纺锤形产量较高,属丰产型;测定不同果形连翘中连翘苷、连翘酯苷A、醇溶性浸出物及农业经济指标百果重,运用主成分分析对不同来源连翘进行了综合评价。其中纺锤形综合评价较好。结论:本实验为连翘品质的提高以及新品种的选育奠定基础。

Objective： To study on the intraspecific variation of Forsythiae Fructus, clarify the morphological characteristics,quality and yield in different habits and different fruit types,and lay the foundation for better development,utilization and protection of germplasm resources as well as breeding of fine varieties of Forsythiae Fructus. Method： The morphological characteristics of different fruit types were observed,and their length,width and yield were measured as basis for determining the type of fruit. The contents of chemical components in different fruit types were measured by using high performance liquid chromatography（ HPLC） and the comprehensive evaluation was then carried out. Result： Upon investigation of intraspecific variation,the fruits of Forsythiae Fructus were classified into long oval,oval,spindle,elongated and round types. The economic indexesand properties of these different fruit types were analyzed and described. The results showed that the yield of spindle shape was highest,so it was among the high yield types. The phillyrin,forsythiaside A,ethanol soluble extraction and weight per 100 fruits in agricultural economic index of different fruit types were measured,and a comprehensive evaluation of different sources of Forsythiae Fructus was carried out by the method of principal component analysis. The comprehensive evaluation of spindle shape was better. Conclusion： This experiment could lay foundation for the breeding of new varieties and the quality improvement of Forsythiae Fructus.
