| Abstract: |
| 【Objective】Examine how the quality of the fruit changes as the four primary citrus kinds (Orah, Bingtang, Murcott, and W.Murcott) in Ruili, Yunnan, develop and mature, and offer a theoretical foundation for calculating the window of opportunity for fruit harvesting.【Method】As test materials, four citrus kinds that are primarily grown in Yunnan were employed. Fruits were harvested 150 days after flowering (August 12, 2020 to April 28, 2021) and 240 days after flowering (November 8, 2021 to February 8, 2022). This 2-year experiment was conducted. Every fifteen days, samples were taken routinely, and the quality of the fruit was assessed. 【Result】The single fruit quality and the horizontal and vertical diameter of the four citrus fruit kinds exhibit a trend of initially growing and then flattening as the fruits mature. In a span of two years, the color transition period of W.Murcott peel is earlier in the second year, and the color transition period of Orah and Bingtang is later than the first year, with the exception of Murcott, which consistently experiences a color transition period before 300 days after flowering. Orah fruits also terminate their rapid growth and expansion period before 270 days after flowering, while Bingtang fruits and Murcott fruits do so before 255 days after flowering. After 240, 315, 300, and 270 days of blooming, respectively, the Bingtang, Orah, Murcott, and W.Murcott all showed stable TSS (total soluble solids content) mass fractions. The mass fractions of TA (titratable acid content) were unchanged at 180, 210, 240, and 240 days of flowering, respectively.【Conclusion】The fruits of Orah, Bingtang, Murcott, and W.Murcott attained harvest maturity at 315 d, 255 d, 300 d, and 285 d after flowering, which was suitable for harvesting, taking into account characteristics like fruit Single fruit weight, fruit form, peel color, and inclusion content. |
