摘　　要：为了筛选出百香果最佳搭架方式,本研究选取5种典型的搭架方式:篱壁式单层架(FBSD)、篱壁式双层架(FBSS)、宽窄行单层架(KZHD)、宽窄行双层架(KZHS)、平棚垂帘式搭架(PPJ),比较分析百香果的产量、营养成分差异,并进一步采用多元统计分析方法对其进行主成分分析(PCA)及综合评价。结果发现:在FBSS和KZHS下百香果产量最高,亩产分别为1156.48 kg和1035.13 kg。不同搭架方式下百香果外观品质未表现出显著差异,百香果糖酸比在FBSD、FBSS、KZHD、KZHS和PPJ不同方式下分别为2.89、2.45、2.72、2.46和2.26。FBSD总氨基酸(TAA)、必需氨基酸(EAA)、风味氨基酸(FAA)含量最高,分别为1366.60、369.64和799.50 mg/100 g,必需氨基酸占总氨基酸的含量为27.05%;FBSS总氨基酸(TAA)和风味氨基酸(FAA)含量最低,分别为948.54和549.68 mg/100 g,必需氨基酸占总氨基酸的含量为29.61%;5种搭架方式甜味氨基酸和酸味氨基酸含量分别占风味氨基酸的37.09%~41.08%、58.92%~62.91%。对39种指标进行PCA,从中提取了4个主成分因子,其累计方差贡献率为100.0%。根据4个主成分方差贡献率建立综合评价模型计算出不同搭架方式的综合总得分,排序为FBSD(2.097)>KZHD(1.836)>FBSS(1.589)>KZHS(1.476)>PPJ(1.229)。说明在这5种搭架方式中,FBSD是百香果种植过程中最佳搭架方式。该研究可以为百香果搭架方式的推广应用奠定理论基础。In order to select the best frame modes of passion fruit,five typical frames were selected in this study:hedge single-layer frame(FBSD),hedge double-layer frame(FBSS),wide-narrow row single-layer frame(KZHD),wide-narrow row double-layer frame(KZHS),flat shed vertical frame(PPJ).Through the analysis and comparison of the difference of yield and nutritional components of passion fruit,and the multivariate statistical analysis method(PCA)was used for principal component analysis and comprehensive evaluation.The results showed that the yield of passion fruit was the highest under FBSS and KZHS,and the yield per mu was 1156.48 kg and 1035.13 kg,respectively.There was no significant difference in the appearance quality of passion fruit among different frame modes,and the sugar-acid ratio of passion fruit in FBSD,FBSS,KZHD,KZHS and PPJ were 2.89,2.45,2.72,2.46 and 2.26,respectively.The contents of total amino acid(TAA),essential amino acid(EAA)and flavor amino acid(FAA)in FBSD were the highest,which were 1366.60,369.64 and 799.50 mg/100 g,respectively.The content of essential amino acids accounted for 27.05%of the total amino acids.The contents of total amino acid(TAA)and flavor amino acid(FAA)in FBSS were the lowest,which were 948.54 and 549.68 mg/100 g,respectively,and the content of essential amino acids was 29.61%.The contents of sweet amino acids and acidity amino acids in the five frame modes accounted for 37.09%~41.08%and 58.92%~62.91%of the flavor amino acids,respectively.Four principal component factors were extracted from 39 indexes by PCA,and the contribution rate of cumulative variance was 100.0%.According to the contribution rate of variance of four principal components,a comprehensive evaluation model was established to calculate the comprehensive total scores of different frame modes,and the order was FBSD(2.097)>KZHD(1.836)>FBSS(1.589)>KZHS(1.476)>PPJ(1.229).It showed that among the five frame modes,FBSD was the best frame modes in the process of passion fruit planting.This study can lay a theoretical fo
