| Abstract: | The growth situation and peroxidase (POD) of seedlings of two tomato cuhivars were investigated under the stress of different concentrations of Cu2+ and Cd2+. The toxicity differences of Cu2+ and Cd2+ to tomato seedlings and the corresponding differences between two tomato cultivars were observed through the stress trial with the above two heavy metal ions. The results showed that low concentration of Cu2+ and Cd2+ could promote the growth and could enhance the POD activity of tomato seedlings, while high concentration Cu2+ and Cd2" could inhibit seedling growth and POD activity of tomato seed-lings. Cd2+ functioned more obviously than that of Cu2+, two tomato cultivars also presented difference in response to heavy metal stress. |
