Growth and iron content of three legume tree species at high root- zone temperature

Abstract

Compared the growth of Gleditsia triacanthos var. inermis (honeylocust), Maackia amurensis (Amur maackia), and Sophora japonica (pagoda tree) at high root-zone temperature. Growth of pagoda tree seedlings is more sensitive to cyclic episodes of high root-zone temperatures than to constant heat. The influence of high root-zone temperature on growth of Amur maackia was similar to that of honeylocust, which in previous studies was more heat resistant than other trees used in temperate urban forests. -from Author
