| 【目的】研究‘桂芒一号’果实生长发育规律及进程，为‘桂芒一号’栽培管理和品质控制提供参考。【方法】以广西南宁地区自主选育的‘桂芒一号’芒果为研究材料，测定果实生长发育过程纵横侧径、单果重、种核重、种仁重及可溶性固形物含量、酸含量等指标，分别采用多项式回归和求导方法建立‘桂芒一号’芒果果实生长发育数学模型和累积速度模型，以期为‘桂芒一号’芒果高产优质栽培管理措施和品质控制提供参考依据。【结果】研究结果表明‘桂芒一号’芒果果实外观生长变化表现为近“S”形，花后37-65d为‘桂芒一号’芒果果实的快速生长阶段，花后110d期开始逐渐出现胎萌现象，120d后熟果实可溶性固形物含量达到采收标准，140d起出现穿根。根据各项指标建立数学模型，各项指标拟合方程有二元三次方程、二元二次方程及指数函数，累积速度方程有二次方程、一次方程及指数函数。【结论】本研究以南宁地区观察测量数据建立的‘桂芒一号’芒果生长发育动态数学模型可为‘桂芒一号’芒果果实发育期的栽培管理技术措施和品质控制提供参考依据。 |

| 【Objective】To providing a theoretical basisi for taking appropriate measures for improving the yield and quality of Guimang 1 mango.【Method】The study used Guimang 1 mango,a locally bred cultivar in Guangxi, as the research material. The growth and development process of the fruit was measured in terms of longitudinal, transverse, and lateral diameters, single fruit weight, seed weight, kernel weight, soluble solids content(SSC), and acid content. Polynomial regression and derivative methods were employed to establish mathematical models of fruit growth and development,as well as cumulative growth rate models. The aim was to provide a reference for high-yield and high-quality cultivation management measures of Gui Mang No. 1.【Result】The results showed that the growth pattern of Guimang 1 fruit exhibited an approximate "S". The rapid growth phase occurred from 37 to 65 days after flowering(DAF). The phenomenon of vivipary began to appear around 110 DAF, and the soluble solids content of the ripe fruit reached the harvest standard after 120 DAF. The phenomenon of root penetration was observed starting at 140 DAF. At 80 days, the morphological development period of the fruit kernel and seed is completed. The fruit kernel is hard and develops earlier than the fruit morphology. However, at 113 days, the seed coat of the seed turns brown and the seed is mature. The fruit does not reach the optimal harvest period until 129 days.The fitted models for various growth indicators included binary cubic equations, binary quadratic equations, and exponential functions, while the cumulative growth rate models were described by quadratic equations, linear equations, and exponential functions.【Conclusion】 In conclusion, the dynamic growth patterns and established mathematical models of Guimang 1 mango can serve as a scientific reference for formulating high-yield and high-quality cultivation management strategies，especially during the fruit development stage. |
