摘要

太魯閣櫟主要分佈於台灣東部：該地區有許多石灰岩發育成的土壤。我們在該地區三處石灰岩土與非石灰岩土直，每處採取四至五侏太魯閣櫟上冠層的葉部並分析其養分。結果顯示除了硼(B)以外，三處太魯閣櫟的藥部養分雖然有差異，但是濃度大至在適當的範圍，並且與其生長的土壤化學性質不具相關性。缺鐵黃化症並未出現在石灰質的土壤上。

Q. tarokoensis is mainly distributed in eastern Taiwan where many soils derived from limestone bedrocks are calcareous. The foliage nutrient concentrations of 4-5 trees of this species were studied on each of 2 calcareous and 1 noncalcareous soils in the region. Results show that some differences in foliar nutrient concentrations among the 3 soils occurred; but except for boron, all other nutrient concentrations were in the range of sufficient values, and differences in foliage nutrient concentrations were not reflected in differences of soil chemical properties. No symptoms of Fe chlorosis were noted in trees growing on calcareous soils.
