Effect of NaCl was studied on chlorophyll (Chl) synthesis and its intermediates (protoporphyrin IX, Mg-protoporphyrin IX, and protochlorophyllide), dry mass, ethylene evolution, and activities of superoxide dismutase (SOD) and peroxidase (APX) in wheat (Triticum aestivum L.) seedlings at 24, 48, and 72 h after germination. A conspicuous decrease in Chl synthesis, associated with increase in ethylene evolution and SOD and APX activities, was noted as NaCl concentration was increased from 0 to 100 mM.

Keywords: dry mass; peroxidase; superoxide dismutase; Triticum aestivum
Subjects: antioxidants; chlorophyll synthesis, NaCl; ethylene evolution, NaCl stress; peroxidases; salt stress, chlorophyll synthesis; superoxide dismutase; Triticum aestivum; wheat, chlorophyll synthesis
