Abstract

To determine an efficient, rapid, and safe measurement for walnuts containing chemical substances, 11 individual Juglans regia walnuts from Hezhang and Puding in Guizhou Province were tested using Fourier transform infrared spectroscopy （FTIRS）. A correlation analysis between FTIR absorbance ratios from the FTIR spectra ［D（1658）/D（3010）, D（1747）/D（3010）, and D（1100）/D（3010）］ and those from a conventional quantitative chemical analysis was employed. The relative ratios of the peaks in the spectra of the 11 individual walnuts were tested using ANOVA（t=11, n=5）and SNK to show differences in contents for various seed components. Results of the ratios among the main components in the walnuts obtained from the FTIR spectra were in favorable agreement with those from a conventional quantitative chemical analysis and had significant correlation coefficients （r＞r0.01（9）=0.735）. The relative ratios of the peaks in the spectra of the 11 individual walnuts showed various components in the seeds all had significant differences using ANOVA（P=0.01）. So, as an easy, fast, and direct technique, FTIR spectroscopy could be used to characterize components and their relative content of plant seeds and could provide a theoretical foundation for breeding and revealing genetic relationships of walnuts in Guizhou. ［Ch, 2 fig. 4 tab. 16 ref.］
