DETECTION OF TRANSGENIC COTTON USING THz SPECTROSCOPY AND WEIGHTED DISCRIMINATE ANALYSIS
Abstract
Terahertz spectroscopy combined with weighted discriminate analysis (WDA) is performed with different transgenic cottons (HD-1, HD-73, and Coker 312). The time-domain spectra of the samples are transformed into frequency-domain spectra by using fast Fourier transform. Then the absorbance curve of the samples is obtained. By applying the absorbance data in conjunction with the WDA model, the identification rates of the different transgenic cottons are 89.4, 89.7, and 92.5%, respectively. The experimental results demonstrate that THz spectroscopy combined with WDA is a novel and feasible way to detect transgenic cottons.
