Abstract:

The objectives are to study the effects of different concentrations of ferrous ions on the growth and accumulation of mineral elements in different parts of sugar beet (Beta vulgaris L.) seedlings, and to provide a basis for sugar beet planting in different soils. In this study, sugar beet variety ‘KWS1176’ was taken as the research material, and the growth status of the seedlings was studied with the Fe2+ concentration of 0.06, 0.12, 0.24, 0.48, 0.96, 1.92 and 3.84 mmol/L (CK, T1-T6) by hydroponic culture, and the contents of mineral elements in different tissues were determined. The results showed that along with the increase of Fe2+ concentrations in nutrient solution, the concentration of Fe in both aboveground and underground parts of the plant increased continuously. The content of plant nitrogen, phosphorus, potassium and other macro-elements showed different degrees of downward trend with the increase of Fe2+ concentration. In addition, the manganese content in plants showed a decreasing trend, while the copper and zinc content increased with the increasing stress degree. In summary, the high concentration of ferrous ions in the substrate will greatly affect the absorption of mineral elements by the seedlings, and have a negative impact on the growth and development of sugar beet seedlings.

Key words: sugar beet, ferrous stress, growth and development, mineral elements
