Excessive and inappropriate application of industrial N fertilizer can result in severe environmental and ecological problems, but whether the input of N fertilizer could affect the composition of mineral elements in corn has not been reported. Effects of input of N fertilizer on the composition of mineral elements (Se, Mo, I, Mn, Fe, Cu, Zn, Ca, Cr, K, Na, and Mg), in corn grain were investigated by ICP-MS (inductive coupling plasma-mass spectrometry). Se, I, Mn, Fe, Zn, Cr, K and Ca were significantly lower in the treatments with N fertilizer compared to a control without N fertilizer. There was a significant negative conrrelation (R) between four mineral elements and N fertilizer input: I, -0.71; Zn, -0.65; Ca, -0.75; K, -0.89. Therefore appropriate... |

In order to compare the nutrition components of transgenic maize seeds (chitinase gene), achieved by the pollen-mediated approach, with its non-transgenic counterpart, Vitamin B1, vitamin B2, fatty acids and essential amino acids of transgenic maize seeds and their counterparts were analyzed by the Chinese national standard methods or AOAC methods. The results showed that the contents of all the six kinds of fatty acids detected in transgenic maize seeds were significantly higher than those in their non-transgenic counterpart, the content of vitamin B2 in transgenic maize was significantly lower than that in non-transgenic maize seeds, the content of total amino acids in transgenic maize seed was higher than that in non-transgenic maize seeds, while... |
