摘要
为了比较不同地理居群大蒜的理化性质差异, 以25份不同地理居群的大蒜为研究对象, 采用傅里叶变换红外光谱仪获取各样品的FTIR图谱, 利用光谱仪随机软件中的“快速比较”功能进行了不同地理居群大蒜的相似度比较。 结果发现, 不同地理居群大蒜的FTIR图谱存在差异, 快速比较显示其相似度为76.3%~99.8%, 呈现出较为明显的多样性分化, 并在一定程度上反映了大蒜种植地居群环境对大蒜理化性质的影响, 为大蒜种质资源的鉴定和评价提供了一种简便、 快捷、 无损的新型方法。
Abstract
In the present paper, 25 garlic samples from different geographical populations were studied. FTIR spectra for each sample were obtained by using Fourier transform infrared spectrometer, and the similarity of garlic samples from different geographical populations was compared through “quick comparison” function in software of the spectrometer. The results showed that there are differences among FTIR spectra of garlic samples from different geographical populations.The quick comparison showed that the similarity is from 76.3% to 99.8% and the diversity of differentiation is more obvious. To some extent, the results reflected the effects of populations environment on physical and chemical properties of garlic. The study provided a simple, rapid, non-destructive and new methods for identification and evaluation of garlic germplasm resources.
