Title: Effects of Cu stress on growth and physiological characteristics of tobacco seedlings.
Abstract: The seedlings of two tobacco varieties(89112 and shuang-70) were cultured under different Cu concentration(0,0.5,1,5 and 10 mg/L) to investigate the effects on the content of MDA and chlorophyll,activity of SOD and POD,and biomass.The results showed that the MDA content first raised and then decreased with increase of Cu concentration,the activity of SOD and POD was increased under the low Cu concentration and inhibited under the high Cu concentration,the chlorophyll content and biomass increased when Cu concentration was below 1mg/L and decreased when Cu concentration was above 1 mg/L.
