20.500.12556/RUL-136017 Apple fruit (Malus domestica Borkh.) metabolic response to infestation by invasive brown marmorated stink bug (Halyomorpha halys Stal.) The brown marmorated stink bug (BMSB; Halyomorpha halys Stal.) has become a significant pest in Slovenia, especially in apple, pear, peach, and cherry orchards. In our study, apple fruit of the apple cultivar ‘Red Pinova’ were evaluated for visual injury and sugar, organic acid, and phenolic contents. The chemical composition of the area around the puncture wound, the uninjured part of the infested apple, was compared to, as a control, only uninjured apples. There was a significant response of the apple around the puncture wound, resulting in an 11.9 g/kg FW higher total sugar content, a 1.4 g/kg FW lower total organic acid content, and an 11.9 g/kg FW higher total phenolic content compared with control apples. A strong phenolic response in the puncture wound area, with high flavanol and hydroxycinnamic acid contents, with increases of 118% and 237%, respectively, compared with control apples, was detected. The brown marmorated stink bug induces a strong phenolic response in the injured area of the apple. The results of this study illustrated how apple fruit responds to the BMSB injury, not only sensorily (visual injury, odor), but also chemically in the form of metabolic responses. injury insect organic acids pests phenolics sugars jablana marmorirana smrdljivka škodljivci rastlin poškodbe kemična sestava plodovi poškodbe plodov sladkorji fenolne spojine organske kisline true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-06 15:10:45 2022-04-06 15:10:46 2022-09-15 04:13:13 0000-00-00 00:00:00 2021 0 0 7 str. iss. 8, art. 212 Vol. 7 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632 2311-7524 10.3390/horticulturae7080212 72388099 RAZ_Zamljen_Tilen_2021.pdf RAZ_Zamljen_Tilen_2021.pdf 1 DF3430E3D0414D9BC17D7AD806AC6D80 9e0a1cf652ee55859f1e9b8d2ee68d9d75c31c871d1333d8188142e466e169cc 2ceb7b67-b5ab-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155436 https://www.mdpi.com/2311-7524/7/8/212 1 ee83eb7e-b5aa-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155435 Biotehniška fakulteta 0 0 0
