| Abstract: |
| Aiming to provide a theoretical basis for the harvest management and oil quality improvement of Gardenia jasminoides fruit by investigating the dynamic changes in oil content, nutrient accumulation, and lipid molecular profiles during fruit development in the cultivar Linhai No.1, fruits from 15 days after flowering (DAF) to 180 DAF were collected to determine oil content and internal component (soluble sugars, soluble starch, and soluble proteins) levels. Additionally, fruit samples at five key developmental stages (15, 60, 90, 105, 150 DAF) were subjected to lipidomic analysis using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Pearson correlation analysis was further employed to explore the relationships between oil accumulation and both internal component contents and lipid molecular species. The results showed that the oil content exhibited a sigmoidal (S-shaped) accumulation pattern from 15 DAF to 180 DAF, which could be divided into four stages: initiation (15-60 DAF), rapid accumulation (60-105 DAF), gradual accumulation (105-150 DAF), and stabilization (150-180 DAF). The oil content stabilized after 150 DAF, reaching 16.72% at this time point. The contents of soluble sugars, soluble starch, and soluble proteins all displayed a unimodal trend (initially increasing and then decreasing) throughout the developmental period. Lipidomic analysis identified a total of 776 lipid species across 5 major categories and 25 subclasses, among which glycerolipids were the most abundant category and triacylglycerols were the most abundant subclass, with contents of 58 925.61 μg/g and 57 153.53 μg/g, respectively, at 150 DAF. At 150 DAF, polyunsaturated fatty acids (PUFA) accounted for 82.2% of total fatty acids, with di-unsaturated species being the most prevalent, and the carbon chain lengths of lipid molecules were predominantly concentrated in the range of C68-C72. Correlation analysis revealed that oil accumulation was closely associated with internal component levels and multiple lipid molecular species. In conclusion, the oil content stabilizes after 150 DAF and the oil exhibits a high proportion of PUFA with desirable quality attributes, it is recommended that Gardenia jasminoides fruits be harvested after 150 DAF. |
