Foliar Nutrient Concentrations of Quercus tarokoensis at Three Locations in Eastern Taiwan-plant analysis

Quercus 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 shows that some difference in foliar nutrient concentrations among the 3 soils occurred; but except for Boron, all other nutrient concentrations were not reflected in difference of soil chemical properties. No symptoms of Fe chlorosis were noted in trees growing on calcareous soils.太鲁阁栎（Quercus tarokoensis）主要分布于中国台湾东部，该区域广泛分布由石灰岩母质发育而成的钙质土壤。本研究针对该区域的2种钙质土壤与1种非钙质土壤，在每种土壤上分别选取该物种的4~5株植株，对其叶片养分浓度展开测定分析。结果表明，3种土壤条件下该树种的叶片养分浓度存在一定差异；但除硼（Boron）外，其余养分浓度均未与土壤化学性质的差异呈现相关性。在钙质土壤上生长的该树种未观测到缺铁性失绿（Fe chlorosis）症状。
