| 中文摘要: |
| 利用傅里叶变换红外光谱（FTIR）法获得4 个茶树群体种质资源的红外光谱图，结合系统聚类和
相关性系数法对所得的光谱数据进行分析比较。结果显示：各茶树群体种的红外光谱整体上十分相似，但由于
内含化学成分及相对含量存在差异，其具有各自的特征红外光谱。根据红外光谱的特征峰形和吸光度值，不仅
可以区分各群体种，而且可以评价其质量。同时，依据红外指纹图谱特征，可以将4 个茶树群体种分为3 个类
群，第一类是龙胜龙脊茶和临桂宛田茶，第二类是凌云白毫茶，第三类是南山白毛茶。FTIR- 聚类分析法可以
作为茶树群体种鉴定和质量评价的一种可行性手段。 |
| 英文摘要: |
| FTIR spectra of four tea germplasm resources were obtained by Fourier transform infrared
spectroscopy（FTIR）method，system clustering and correlation coefficient method were used to analyze and
compare these spectral data. The results showed that，Because of the different proportion of chemical constituents
in each tea germplasm resource，although there was a great similarity in infrared spectrum，the results still showed
differences in the characteristic peaks of infrared spectrum among four tea germplasm resources. According to the
spectral peak and absorbance ratio，four tea germplasm resources could easily be identified，and different quality
could be evaluated. By infrared fingerprinting，four tea germplasm resources could be divided into three categories，
the first category included：Longsheng Longji tea and Lingui Wantian tea；The second category included Lingyun
baihao tea；The third category included Nanshan Baimao tea. FTIR-cluster analysis can be used as a feasible method
for the identification and quality evaluation of tea germplasm resource. |
