| 摘 要： | 利用红外光谱(傅里叶变换红外光谱(FT-IR)、二阶导数红外光谱(SD-IR)和二维相关红外光谱(2 D-IR))研究人工老化水稻种子。结果表明,人工老化水稻种子的原始光谱整体相似,二阶导数光谱在1800~800 cm-1范围内的吸收峰强度和形状出现差异。二维相关光谱显示,水稻种子随老化时间的增加,在800~1350 cm-1范围内自动峰的位置和强度显示差异。研究表明,红外光谱可以对人工老化水稻种子进行快速有效的检测。

| Abstract: | In this study,the artificial aged rice seeds were studied by Fourier transform infrared spectroscopy(FT-IR),second derivative infrared spectroscopy(SD-IR)and two dimensional correlation infrared spectroscopy(2 D-IR).The results showed that the original spectra of artificially aged rice seeds were similar on the whole,and the intensity and shape of the absorption peaks varied from 1800 to 800 cm-1 in the SD-IR.Meanwhile,the 2 D-IR showed that the position and intensity of the automatic peak in the range of 800 to 1350 cm-1 were different with the increase of the aging time.In conclusion,the results showed that infrared spectroscopy could detect the artificial aged rice seeds quickly and effectively. |
