Changes in isoenzyme profiles of antioxidative enzymes, superoxide dismutase, peroxidase and catalase, in leaves of Impatiens flanaganiae Hemsl. subjected to different light conditions were investigated. and H 2 O 2 themselves is relatively low, their metal-dependent conversion to the highly toxic OH is thought to be responsible for the majority of the biological damage associated with these molecules (Elstner 1982 , Allen 1995 . There are three modes by which photo-oxidative stress
