Abstract
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.
Highlights
Arachis hypogaea is an annual herb of the genus of Arachis in leguminous family [1]
When Mn was at the concentration of 900 μmol/L, the plant height of peanut was the lowest, indicating that high concentration of Mn might inhibit the growth of peanut seedlings
The results showed that the growth of lateral roots might be inhibited at high concentration of Mn
Summary
Arachis hypogaea is an annual herb of the genus of Arachis in leguminous family [1]. The provinces of Shandong, Guangdong, Guangxi, Hebei, Henan, Liaoning, Anhui and Sichuan are the main producing areas of peanut in China [2]. The oil contains 19%-43% linoleic acid, which is the essential fatty acid for human body, and its protein contains a large number of essential amino acids for human body; and the composition proportion of oil and protein is appropriate, and the effective utilization rate is high [4]. It contains calcium, iron, phosphorus and a variety of vitamins, which are extremely rich in nutrients and play a very important role in human growth and disease resistance maintenance [4]
