【摘要】 利用傅里叶变换红外光谱结合二维相关红外光谱对不同萌发天数的油菜种子进行研究。结果显示，油菜种子的一维原始光谱主要由脂质峰、蛋白质峰、糖类峰组成；与对照组（未做萌发处理）相比，萌发油菜的脂质、糖类和蛋白质的含量发生明显变化。在对1 700～1 000 cm^-1光谱范围内的二维相关红外光谱分析中得出，对照组与萌发油菜的自动峰数量、强度、位置均发生明显变化。结果表明傅里叶变换红外光谱是研究萌发油菜种子的一种快速、简便的方法。更多还原

【Abstract】 Fourier transform infrared spectroscopy combined with two-dimensional correlation infrared spectroscopy were used to study germinated rape seeds. The results showed that the one-dimensional original spectra of varies kinds of rape seeds were mainly composed of the characteristic peaks of lipid, protein, saccharides. Compared with the the control group（without germination treatment）, the contents of lipid, saccharides and protein in the germinated rape seeds changed significantly. The number, intensity and position of auto-peaks of the control and germinated rape seeds were different in the two-dimensional correlation infrared spectra in the 1 700～1 000 cm^-1 range. The results showed that FTIR spectroscopy was a rapid and simple method for studying germinated rape seeds.更多还原
