The objective of this study were to investigate the fruit disorders, development and mineral composition of 'Chiin Hwang ' by different bagging material. Results indicated that the fruit growth pattern appeared a sigmoid curve. In the fruit mineral concentrations, there were no significant differences in nitrogen and potassium between peel and pulp, but the peel was found high in calcium and magnesium. The black paper bagged friuts had a higher nitrogen concentration the other treatments. There were no significant differences in calcium concentration s than between treatments. The N/Ca, K/Ca and Mg/Ca of friuts were higher in black-paper treatment, likewise the percentages of the friut disorders. Fruit analysis data indicated that the mineral concentrations were elevated in the affected fruits especially in the middle portion and styler-end in breakdown fruits. The N/Ca, K/Ca and Mg/Ca of friuts were higher in the affected fruits than the healthy ones after ethrel treatment.本試驗調查'金煌'芒果果實劣變情形，探討不同材質套袋對'金煌'芒果果實生長發育及成份變化的影結果顯示，果實生長曲線均呈單S型，在果實養分方面以黑袋的氮含較高，在鈣含量方面，各套袋處理間均無明顯差異；其中以白袋之果實氮/鈣、鉀/鈣及鎂/鈣比較低，且果實劣變率亦低。比較劣變果與正常果之各部位養分含量，劣變果實之各部位含量均較正常果為高，氮/鈣、鉀/鈣及鎂/鈣比亦較正常果為高
