摘要：

Volatile profiles emanating from stored potatoes inoculated with pathogens Erwinia carotovora and Fusarium roseum were monitored using a dynamic headspace analysis method to investigate their possible use in a system for detection of disease. Small containers filled with sound and disease‐inoculated potato tubers were purged continuously with purified air and the volatiles concentrated on polymeric adsorbent (Chromosorb 105) located at the container outlets. Subsequently, the trapped volatiles were thermally desorbed and analyzed by GC and GC‐MS. Examination of the normal and disease‐induced volatile profiles indicated differences in the range of metabolites produced. Pentane and especially dimethyl disulfide dominated the profiles of potato tubers infected with Erwinia carotovora and Fusarium roseum, but were not detected in the headspace above noninoculated samples. At least one additional compound was unique to the Fusarium dry rot infection. Copyright © 1990, Wiley Blackwell. All rights reserved
