| 摘 要： | 以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法获取各样品的红外谱图及不同波数下各样品的透过率数据,运用主成分分析及聚类分析等统计学方法对谱图数据进行了比较分析。结果发现,不同地理居群大蒜的红外指纹图谱存在差异,统计学分析结果显示25个品种大致可分为4大类(其中2个样品,4号及25号与这4类间有较大差异),此现象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。

| Abstract: | Twenty five samples of garlic collected from different geographical areas were studied by FT-IRS and their fingerprints were established.Comparative study on the FTIRS data was made by applying the chemometrical methods of principle component analysis(PCA) and clustering analysis.It was shown by the results that: ① chemical composition and relative contents(in %) of the components were found to be different for samples from different geographical areas or populations,which furnished as a base for differentiation of sources of garlic;② as shown by PCA and clustering analysis,the 25 samples could be classified into 4 groups,leaving 2 samples(25# and 4#) locating far apart from the 4 groups;and the grouping was related significantly with the geographical and environmental factors,e.g.the hindrances of gene exchange due to geographical spaces;populational environments of the plantation area of garlic and etc. |
