不同种质黄果枸杞数量性状及其颜色差异比较

Comparison of Quantitative Characters and Color Differences of Yellow Wolfberry With Different Germplasm

以7个黄果枸杞品种(系)为试材,采用田间试验的方法,研究了不同种质黄果枸杞14个数量性状及其颜色的差异性,对其色度及与颜色有关的营养成分进行相关分析,以期为黄果枸杞优质育种和开发利用提供参考依据。结果表明:1)“宁农杞4号”和‘W-13-26’聚为一类,表现为花冠直径大、果型大、叶片大;其它5个黄果枸杞品种(系)聚为一类,表现为花冠直径小、果型小、叶片小。2)14个数量性状中叶片的变异程度高于果实和花性状。3)7个黄果枸杞品种(系)的果实颜色互相之间具有显著差异(P<0.05),其中‘W-11-14’的亮度L、色度角h最大,红度a最小;“宁夏黄果”的红度a、黄度b、饱和度c最大;‘HZ-13-01’除红度a以外其它色度指标均为最小。4)黄果枸杞果实中总类胡萝卜素含量与果实红度a、黄度b、饱和度c呈极显著正相关关系(P<0.01);黄酮含量与果实红度a呈极显著正相关关系(P<0.01),与饱和度c呈显著正相关关系(P<0.05)。

Seven yellow wolfberry varieties(lines)were used as test materials,the method of field trials was used,14quantitative characters and color differences of different germplasm yellow wolfberry were studied,and a correlation analysis between the chromaticity and the nutrient composition related to the color was conducted in order to provide a reference for the high-quality breeding,development and utilization of yellow wolfberry.The results showed that,1)‘Ningnongqi 4’and‘W-13-26’were aggregated in one category,the diameter of the corolla was large,the fruit shape was large,and the leaves were large.The other five yellow wolfberry varieties(lines)were grouped into one type,which showed that the corolla had small diameter,small fruit shape and small leaves.2)Among the 14 quantitative traits,the variation degree of leaves was higher than that of fruit and flower traits.3)The fruit colors of 7yellow wolfberry varieties(lines)were significantly different from each other(P<0.05),among them,the brightness(L)and chromaticity angle(h)of‘W-11-14’were the largest,and the redness a was the smallest.‘Ningxia Huangguo’had the highest redness(a),yellowness(b)and saturation(c).The‘HZ-13-01’was the smallest except for the redness(a).4)The content of total carotenoids in the fruit of yellow wolfberry had a very significant positive correlation with fruit redness(a),yellowness(b)and saturation(c)(P<0.01).The content of flavonoids had a very significant positive correlation with fruit redness(a)(P<0.01),which had a significant positive correlation with saturation(c)(P<0.05).
