| Abstract: |
| 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. |
