The effects of different menganses (Mn) concentrations on the growth and development of peanut seedlings were analysed in the present study. The results showed that the main root length, lateral root number, plant height, dry weight of aboveground and underground parts of peanut seedlings were all influenced by the concentrations of Mn obviously. Moreover, the growth of peanut could be significantly promoted at low concentration of Mn (150 μmol/L), while inhibited by high concentration of Mn (900 μmol/L). Therefore, these conclusions could help us to understand the most suitable concentration range of Mn for the growth of peanut, and could also analyze the specific performance of the harm of Mn toxicity on peanut, so as to lay a theoretical foundation for improving the yield of peanut and expanding the cultivation area.
