| dc.description.abstract | Variation of fruit characters within and among trees were studied in two shriveled-seed varieties of ‘Sah Keng’ and ‘Kang Wei’ and the most widely cultivated normal-seed variety ‘Hak Ip’. Analysis of variance showed that the variation among trees contributed more to the total variability than that within tree. Analysis also indicated that the variation among locations was much greater than that of within and among trees, in ‘Hak Ip’ variety.
In general, fruit length, fruit diameter, fruit weight, shell weight, and aril weight were not significantly different within tree. The protuberance of the shell, aril color, percentage of shrivelled seeds and ratio of aril weighs in fruit were not significantly different both within and among trees in most locations. The variation of soluble solids, flavor and seed size were different depending on the varieties and locations.
The shrivelled seed of ‘Sah Keng’, ‘Kang Wei’ and ‘Hak Ip’ were 36%, 26%, and 0%, respectively. Eating quality of shrivelled-seed fruits were superior to normal-seed fruits in smaller seed size and higher aril ratio. The fruit diameter, fruit Weight, and shell weight were highly correlated to seed size in two shrivelled-seed varieties, but not in normal-seed variety. The fruit size and fruit weight of normal-seed variety were larger and heavier than shrivelled-seed fruit, however, the soluble solids was not significantly different.
研究荔枝小核種沙坑及港尾晚生與大核種黑葉果實性狀品種間、株間與株內之變異，由變方分析結果顯示果實性狀株間變異大於株內變異；最廣泛栽培黑葉之四個地區綜合分析結果顯示地區間果實性狀變異大於株間及株內。果長、果徑、果重、果殼重及果肉重等性狀株間之差異為顯著，而株內差異不顯著斗在多數地區之果棘、果肉色、小核率及果肉率於株間及株內之差異均不顯著；而可溶性固形物，風味及種子大小之差異因地區及品種而有異。
沙坑、港尾晚生及黑葉等品種之小核率分別為 36%、 26%及 0%，二小核種之可溶性固形物與黑葉種相近，其他性狀之差別亦於本文中分別比較。
比較小核種沙坑及港尾晚生品種內大核果及小核果之差異，顯示大核果之果實大小及果重略大於小核果；但其可溶性固形物含量差異不顯著。小核果較大核果之優點為種子小，高果肉率及易於剝除果肉。二小核種之果徑、果重及果殼重與種子大小之相關均高且顯著，而大核種果實性狀和種子大小之相關係數均低且不顯著。 | en_US |
