Title:
Concentrations of nitrate, organic acids, free amino acids, cations and sugars in komatsuna (Brassica campestris var. perviridis) grown with carbonate, sulfate and chloride application
Publication date:
2008
Summary:
The concentrations of nitrate, organic acids, free amino acids, cations and sugars in komatsuna (B. campestris var. perviridis cv. Osome) grown in soil treated with carbonate, sulfate and chloride (CO3-TK, SO4-TK and Cl-TK, respectively). Komatsuna was cultivated in pots (6 hills per pot) filled with light-colored Andosol in a greenhouse for 37 days with a soil water potential (SWP) right before harvesting of -6.2 and -62 kPa. Carbonate, sulfate or chloride at 26.5 mmolc each in the form of potassium salts was applied to each pot. Chloride application to komatsuna induced relatively high concentrations of potassium, calcium and magnesium ions, and the low concentrations of malate, glucose and fructose on a dry weight basis. Carbonate application induced relatively high concentrations of malate and low concentrations of nitrate. Sulfate concentration was almost intermediate between chloride and carbonate concentrations. The variation in concentration was not substantial for free amino acids. These tendencies were almost the same under both SWPs. Most of the variations in component concentrations were attributed to the regulation of ionic and osmotic balance as a response to chloride, nitrate and sulfate absorption, as evident in the quantitative relationships among the components and water in komatsuna. The absorption of nitrate appeared to be influenced by the pH of the soil. Marked differences in glucose, fructose and malate concentrations were evident among CO3-TK, SO4-TK and Cl-TK on fresh and dry weight bases.
