Nasturtium officinale exposed to low temperature at 10-12°C was investigated to study the possible application of eutrophicated waterbody resoration in winter of some parts of China. The fresh weight, soluble protein and photosynthetic pigments as well as antioxidant enzymes and biomass changes were measured to study the effect of low temperature on the growth of this plant. The results demonstrated that the soluble protein of Nasturtium officinale at low temperature increased compared with that of plant that grown in optimum temperature, so this plant can synthesize higher level protein to resist low temperature stress. The biomass of Nasturtium officinale also increased at such low temperatures. SOD and POD activity increased to resist oxidative stress when the plant was exposed to low temperature of 10-12°C. CAT activity and MDA content of Nasturtium officinale did not change much at such low temperature. Only photosynthetic pigments decreased in low temperature compared with that of plant grown in optimum temperature.The plant did not suffer from seriously oxidative damage at such low temperature condition, so the plant is suitable for using in the wading eutrophicated natural waterbody restoratin in winter of some part of China.
