摘要
为选取秭归本地最佳核桃优株,以秭归野外调查36个株系核桃初选优株为基础,采用单项外形理化性质比较和主成分分析方法分析了果实品质并进行评价。结果表明,ZG08的单果重最大,达到21.62 g;ZG35的可溶性蛋白含量最高达到90.22 mg·g^(-1);ZG10和ZG03出仁率高达58.47%和57.81%;ZG09和ZG12粗脂肪含量高达82.83%和80.17%;经由36个初选优株主成分分析评价得分排名前十的优株为:ZG33、ZG09、ZG04、ZG05、ZG36、ZG31、ZG08、ZG10、ZG35、ZG18。可以得出初步结论:核桃油加工为主的优株为ZG09,核桃种仁加工为主的优株为ZG10,食用干果优株为ZG08,综合用途优株为ZG33。研究结论为综合评判核桃坚果品质的优劣,为核桃定向育种和分类经营提供科学的参考。
In order to select the best local Juglans regia superior trees in Zigui,based on the preliminary selection of 36 J.regia strains through field investigation in Zigui,the fruit quality was analyzed and evaluated using single item comparison of physical and chemical properties and principal component analysis methods.The results showed that ZG08 had the highest single fruit weight,reaching 21.62 g;The highest soluble protein content of ZG35 is 90.22 mg·g^(-1);The kernel yield of ZG10 and ZG03 is as high as 58.47%and 57.81%,respectively;The crude fat content of ZG09 and ZG12 is as high as 82.83%and 80.17%,respectively;The top ten superior plants with scores evaluated through principal component analysis of 36 primary selected ones are ZG33,ZG09,ZG04,ZG05,ZG36,ZG31,ZG08,ZG10,ZG35,and ZG18.Preliminary conclusions can be drawn:the optimal plant for J.regia oil processing is ZG09,the optimal plant for J.regia kernel processing is ZG10,the optimal plant for dry fruit sales is ZG08,and the optimal plant for comprehensive use is ZG33.The research conclusion provides a scientific reference for the comprehensive evaluation of the quality of J.regia nuts and for the targeted breeding and classification management of walnuts.
