Influence of Armillaria root rot on the foliar nutrients and growth of some coniferous species

摘要

AbstractArmillaria root rot induces a reduction in the concentrations of N, P, K, Mg and Na; an increase in the levels of Ca, Mn, Fe and Zn; and a decrease in the annual height growth of the diseased trees of four coniferous species. The data indicates that these changes are caused by interferences in the metabolism of the infected host.
