不同根砧對椪柑葉內無機養分及果實品質影響

Influence of Citrus Rootstocks on Leaf Inorganic Nutrients and Fruit Quality of Ponkan Trees

本試驗在探求椪柑採用酸橘及廣東檸檬作根砧時，對於椪柑葉內無機養分濃度及果實品質影響。分析結果獲知兩種根砧之椪柑葉內鈣濃度及果汁率均有顯著差異，葉內鈣濃度因根砧不同而有差異，果汁率則可能受葉內鈣濃度影響。

The influence of rootstock on leaf mineral nutrition and fruit quality of Ponkan on two rootstocks was studied. Pronounced differences in leaf Ca and fruit juice percentage were detected. The level of leaf Ca was related to rootstock suggesting a different absorption of mineral nutrients by rootstock. The fruit juice percentage appeared to be influenced by the level of leaf Ca.
