摘　　要：应用傅里叶红外光谱(FTIR),测试分析了4种番茄花粉样品的一维红外谱和二阶导数谱。结果表明,番茄花粉富含蛋白质、氨基酸和碳水化合物类成分;航天诱变选育番茄花粉的图谱与普通系统选育花粉的图谱基本类似,但在个别峰位处发生了变异。2种航天诱变选育花粉产生的共同变异是CH3和C—O振动峰增强;不同的是大小番茄航天诱变选育花粉分别在酰胺Ⅰ带和酰胺Ⅱ带处的吸收增加。Four tomato pollen line（two tomato pollen lines with space flight mutagenesis, and two common tomato pollen lines） were studied by FTIR The method combines two steps： FTIR spectra, and second derivative spectroscopy. The results indicate that the LR spectrum of tomato pollen is mainly composed of absorption of protein, amino add, and carbohydrates, etc, and IR spectrum shows a small change. The same change occurs lot the two space tomato： the absorhance appearsat 1 100-830 cm ^-1 region and 1 390 cm^-1 peak is stretching. However, absorbance at 1 645 cm^-1 was stretching for the big space tomato, while the absorbance at 1 535 cm^-1 was stretching for the small space tomato.
