Abstract: The research aimed at studying the effect of different concentrations of nanometer iron oxide on tomato growth. Using different concentration of nanometer iron oxide to deal with tomatoes,and measure the biomass,anti-oxidizing system,lipid peroxidation and contents of soluble sugar. The results showed that,after dealing with different concentration of nanometer iron oxide,the biomass had obvious change;and anti-oxidizing enzymes,contents of soluble sugar had marked variation. The trend mainly showed first increasing then falling,and tomatoes had the best growth status at 50 mg/L of nanometer iron oxide,showing the obvious growth-promoting effect. It was concluded that,different concentration of nanometer iron oxide had influence on the tomato growth,low concentrations can promote growth,while high concentrations can cause noticeable oxidative stress reaction of tomato.

Key words: nanometer iron oxide, tomato, growth behavior
