以从国外引进的5个蓝莓品种为供试材料,研究其在丽江种植条件下果实的外观指标(果实横径、纵径、单果重、果形指数、色泽等)、营养成分(维生素C、可溶性蛋白质、游离氨基酸、可溶性糖、淀粉和花青素等),并利用主成分分析法对所有指标参数进行分析.结果表明:奥尼尔有最优的果形指数(0.86)、最高的单果重(1.87 g)和花青素含量(440.5μg/g),较高的可溶性糖含量(16.69％)、维生素C含量(0.35 mg/g)和游离氨基酸含量(41.11μg/g).主成分分析提取了2个主成分,累计方差贡献率为85.635％,综合评分奥尼尔最高,为最优品种,适合引种栽培及作为育种材料.
Fruit Evaluation of Five Blueberry Varieties Based on Principal Component Analysis
Taking five blueberry varieties introduced from abroad as the experimental materials,the appearance indicators (such as transverse diameter, vertical diameter, single fruit weight, fruit shape index, color, etc.) and nutritional components (such as vitamin C, soluble pro-tein, free amino acids, soluble sugars, starch and anthocyanins) of their fruits under planting conditions in Lijiang were studied. Principal component analysis was used to analyze all indicator parameters.The results showed that O'Neal had the highest fruit shape index (0.86), single fruit weight (1.87 g) and anthocyanin content (440. 5 μg/g), as well as a higher content of soluble sugars (16. 69％), vitamin C (0.35 mg/g) and free amino acids (41.11 μg/g). Two principal components were extracted in the principal component analysis, with a cu-mulative variance contribution rate of 85.635％. The comprehensive evaluation of O'Neal was the highest, making it the best variety suitable for introduction and cultivation, and also the best variety as a breeding material.
