Effects of pollination cultivars on the characteristic volatile organic compounds in pears using <i>E</i>-nose, HS-SPME-GC-MS, and HS-GC-IMS.

ABSTRACT: Xenia effect significantly influences fruit quality, with underexplored impacts on pear aroma. This study systematically evaluated eight cultivars' effects on 'Starkrimson' pears using electronic nose (E-nose), headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS), and headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS). Pollination with 'Zaosu' (ZS) pear maximized volatile organic compound (VOC) concentrations (terpenoids, esters, aldehydes) and achieved optimal solid-acid ratio (291.78), enhancing fruity, green, and sweet aromas. Conversely, 'Huagai' (HG) pear pollination reduced VOC accumulation and fruit quality. Other cultivars showed intermediate effects on total soluble solids (TSS), titratable acidity (TA), and aroma.
