摘要: Abstract The effects of elevated O3 in different soil conditions on foliar elements stoichiometry were investigated 3 native tree species with a free-air enrichment system northern Japan over two growing seasons. Essential (Mg, K, Ca, Mn, Fe, Ni, P, N) and non-essential (Cr, Al) analyzed leaf samples obtained from 6 treatments soils at 5 collection times 2014 to 2015. In this study, relationships among the within each negative correlations between N metal observed birch (Betula platyphylla var. japonica). From differences contents as well their retranslocation rate, beech (Fagus crenata) determinate shoot growth pattern rather more sensitive stress contents, meanwhile oak (Quercus mongolica crispula) was possibly susceptible dynamics immobile elements. Soil nutrients have distinct impacts rate P. Principal component analysis revealed that Mn K can become indices assessing both short long term monitoring these species. Our findings are essential further comprehension nutrient conservation mechanism cool-temperate forests.
