摘要： 1. 'Fairchild'和艷陽柑為典型的單s生長曲線.'Fairchild'和艷陽柑果實總酸含量隨果實發育而下降,糖隨果實之發育而增加.酸含量中以檸檬酸為主,總酸含量下降乃是因檸檬酸含量下降所致.糖以果糖和蔗糖為主. 2. 探討艷陽柑和'Fairchild'果實最適當之鮮食採收期.'Fairchild'於花後36週糖酸比達20以上,風味佳,為早熟品種.艷陽柑花後39週糖度高,顏色佳,但酸度仍高,宜貯藏. 3. 艷陽柑果實採後以12.5 ℃冷藏之效果優於簡易通風式貯藏。'Fairchild' and 'Sunburst' tangor growing in Chia-yi of Taiwan had a typical single sigmoid growth pattern. The total soluble solid content in 'Fairchild' and 'Sunburst' tangor increased and the titratable acidity（]﹪Mas citric acid）^ decreased during ontogency. The results indicated that the harvest time of 'Fair child' and 'Sunburst' tangor can be 36 weeks and 39 weeks after anthesis, respectively.
The optimum storage temperature of 'Sunburst' tangor is at 12.5℃J.
