IDENTIFICATION OF NEW VOLATILE COMPOUNDS IN THE CITRUS HYBRID MANDARINQUAT 'INDIO'
The volatile composition of the hybrid mandarinquat Indio peel extract was investigated for the first time. In-depth gas chromatography-mass spectrometry (GC-MS) analysis of the chromatograms showed a high complexity, likely due to the addition of traits from both parents. Consequently, many minor peaks could not be identified due to co-elutions, which generated unknown mixed MS spectra. Further investigation based on a more sophisticated processing procedure (deconvolution software) and advanced chromatographic techniques (heart-cut multidimensional gas chromatography) have been carried out. Compared to deconvolution software, the use of a two-dimensional GC-MS system proved to be more efficient to elucidate the co-elutions. Finally, our study showed that, even though the hybrid contained many of the compounds found in one or both parents, a few compounds that have never been identified in any of the parents were identified. The presence of these volatile compounds in hybrids may result from the interaction between the two genomes during hybridization, in which one may cause the activation of some genes in the other, which are otherwise silent in the parent genome.
