摘    要:针对植物航天育种变异大的特点,利用傅里叶变换红外光谱(FTIR)结合二阶导数谱对第4代航天育种白芷与地面组白芷从整体上对主要组分进行测定和对比分析。结果表明:太空白芷主要活性成分香豆素类组分(1 741cm-1)含量增加,蛋白质(1 459,1 419cm-1)和脂肪(930cm-1)组分含量略有增加;而淀粉、膳食纤维(1 152,1 105,1 080,1 050cm-1)的含量大幅度降低。二阶导数谱中峰强差异更明显,1 279cm-1处揭示出太空白芷含有胺类组分。航天育种有利于选育出变异幅度大的特异质白芷新品种。

Abstract:The major components of the 4th generation outer space bred angelica and the ground group were determined and analyzed by Fourier transform infrared spectroscopy (FTIR) and second derivative spectrum, considering the large mutation of the plants with space mutagenesis. The results show that the content of the coumarin (1741 cm(-1)), which is the main active components of the space angelica dahurica increased, and the content of the protein (1 459, 1 419 cm(-1)) and the fat (930 cm(-1)) increased slightly, whereas the content of the starch and the dietary fiber reduced drastically. There are obvious differences between the peak values of the second derivative spectra of the plants, revealing that the outer space angelica dahurica contained amine component at 1 279 cm(-1). Space mutation breeding is favor of breeding angelica with better idiosyncrasy.
Keywords:Space mutagenesis  Angelica dahurica  FTIR
