Abstract: 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 foundation for the popularization and application of passion fruit.
