摘　　要：【目的】了解黑果枸杞果实表型变异及表型与活性物质的关联,为其资源开发利用提供参考。【方法】以黑果枸杞果实为试材,提取23个表型特征,并测定其活性物质进行分析。【结果】(1)表型特征圆度、相关性值和熵值变异系数较小,个体间差异小,稳定性高,面积、黄蓝通道值、红绿通道值、对比度和角二阶矩值变异系数较大。(2)活性物质含量变异系数均较大,稳定性差,选择潜力大。表型特征和活性物质间143对相关系数呈极显著水平(P<0.01),20对相关系数呈显著水平(P<0.05)。(3)主成分分析表明红度、绿度、蓝度、亮度、明度、灰度、周长、面积、长度、宽度、角二阶距和能量值特征向量值较高,可作为其果实品质评价的重要参考因子。【结论】黑果枸杞果实有较大的选择潜力,可通过表型特征判断活性物质含量,试验结果可为果实品质评价及无损检测提供参考。[Objective]The aim was to understand the phenotypic variation of Lycium ruthenicum Murr.fruits and the correlation between phenotype and active substances,to provide reference for its resource development and utilization.[Methods]Taking L.ruthenicum as materials,23 phenotypic characteristics were extracted,and the active substances were determined and analyzed.[Results](1)The coefficient of variation of roundness,correlation value and entropy of phenotypic characteristics was small,the difference between individuals was small,and the stability was high.The coefficient of variation of area,yellow-blue channel value,red-green channel value,contrast and angular second moment value was large.(2)The coefficient of variation of active substance content was large,the stability was poor,and the selection potential was large.The correlation coefficients between phenotypic characteristics and active substances were extremely significant in 143 pairs(P<0.01)and significant in 20 pairs(P<0.05).(3)Principal component analysis showed that the characteristic vector values of red,green,blue,brightness,lightness,gray,perimeter,area,length,width,angular distance,and energy value were higher,which could be used as important reference factors for fruit quality evaluation. [Conclusion] The fruits of L. ruthenicumhave great potential for selection, and the content of active substances can be judged by phenotypiccharacteristics. These results provide reference for fruit quality evaluation and non-destructive testing.
