Abstract
The growth of seeded and seedless fruits of ‘Sah Keng’ variety litchi was studied. The seed grew rapidly in the early stage, the normal and aborted seeds could not be macroscopically distinguished until about 30 days after full bloom. The volume and weight of normal seed increased continually and attended full size about 50 days after full bloom, however the aborted seed grew slowly and ceased about 40 days after full bloom. The growth of volume of seeded fruit, expressed as three components length, diameter and thickness, was larger than seedless fruit. Increase in fruit length mainly occurred at early stage while that in diameter and thickness mainly occurred at later stage. Fruit weight increased rapidly in the later stage due to the growth of aril. The weight of seeded fruit was heavier than seedless fruit through growth period, but the aril weight between seeded and seedless fruit were not significantly different. It suggested that the seed size might he less important on the growth of aril in litchi. The total soluble solids in fruit increased continually and reached the maximum at maturity. The total soluble solids of seeded fruit was higher than seedless fruit, but not significantly.
研究荔枝沙坑種正常果及焦核果各構成部份之生長顯示種子於初期迅速增大，至花後 30 天正常及焦核種子發育即有顯著不同，此後正常種子之體積及重量均繼續增加，至花後 50 天即接近成熟大小，焦核則生長緩慢至 40 天即停止發育。果實體積以果長、果徑及果厚表示，正常果均大於焦核果，果長於初期增加較速，果徑及果厚在後期增加較速。果重在發育後期因果肉之生長而迅速增加，於發育過程，正常果之果重均顯著大於焦核果，但果肉重之差別則不顯著，顯示種子大小對果肉生長之影響不大。果肉可溶性固形物含量於發育期持續增加，至成熟期達到最高，正常果之可溶性固形物含量高於焦核果，但二者差異不顯著。
