As for Leucaena leucocephala seedlings, MDA is not the main product of lipid peroxidation and Tephrosia candida seedlings do not only rely on SOD and POD action to reduce active oxygen content. Through comprehensive analysis on water holding capacity of leaf, cytomembrane permeability, MDA content and SOD, POD activity, Dodonaea viscosa seedlings show the highest drought resistance, then Leucaena leucocephala, Tephrosia candida the last.
