| 内容記述 | In this study, we used stable carbon isotope ratios (C-13/C-12) in crop and soil samples. It is well known that C-13 and C-12 are fractionated in the photosynthesis process at a certain ratio, depending on plant types, i.e. C3, C4 and CAM plants. If all the carbon in crops originated only from the air, the stable carbon isotope ratio would take a constant value; however, if there were any contributions from soil carbon, the ratio would be changed. This approach has been used in our previous study for rice (Tagami and Uchida, 2009) and we tried to use the method for leafy vegetables. Leafy vegetables were cabbage, Chinese cabbage, lettuce, and leeks, and associated soil samples were collected in Japan. Stable carbon isotope ratios and total C concentrations using an elemental analyzer connected to an isotope ratio mass spectrometer (Thermo Fisher Scientific, Flash EA and Delta V Advantage). Finally we found that the percentage of soil origin carbon to the total plant carbon was 2.9%, and the soil-to-plant transfer factors ranged 0.12-1.1 with an average of 0.5, which was within the previously reported values for radish (Sheppard et al., 1991). |
