摘　　要：利用傅里叶变换红外光谱仪分别检测17种姜科植物的的光谱特征,并通过系统聚类和相关性系数法来探讨各植物间的亲缘关系。结果显示,聚类分析树系图和相关性分析结果相吻合,当花叶山姜和黑果山姜的距离系数为1(最小),相关系数为0.991(最高),亲缘关系最近。该研究得出同亚属植物间、野草果与山姜属植物属近缘种,支持了顶花莪术、温郁金在分类系统中的独立性,建议划分为独立种。聚类分析中姜科植物种间的聚合较好,物种鉴定正确率达到100%。因此,FTIR结合聚类分析法在姜科植物物种分类及鉴别中是一种可行性手段。FTIR spectra from 11 kinds of Zingiberaceae by Fourier transform infrared spectroscopy method combined with the system clustering and correlation coefficient method were used to explore the relationship among the plants.The results show that the cluster analysis is consistent with the results of the correlation analysis,When the distance coefficients of A.kwangsiensis LSSR was 1（minimum）,the correlation coefficient was 0.950（highest）,phylogenetic relationships recently;25（maximum distance coefficient A.blepharocalyxandC.wenyujin）,correlation coefficient of 0.005（minimum）,phylogenetic relationships farthest.The study draws that A.kwangsiensis and LSSR,C.xanthorrhiza and A.petaloideumare closely related to species,and supported the independence of C.wenyujinand C.yunnanensis in the classification system,the proposal is divided into separate species.The clustering analysis of the plant species is better,and the correct rate of species identification was 100%.FTIR-cluster analysis can be used as a possible means for the classification and identification of Zingiberaceae.
