20.500.12556/RUL-140923 Effect of brown marmorated stink bug (Halyomorpha halys Stål.) infestation on the phenolic response and quality of olive fruits (Olea europaea L.) Olives ripen in the late autumn and represent a good source of nutrients that Halyomorpha halys uses to prepare for diapause. This is the first study to investigate the impact of H. halys infestation on the phenolic response and olive fruit quality in the pierced tissue of damaged fruits and in the non-pierced part of damaged fruits of ‘Istrska belica’ and ‘Pendolino’ cultivars. Both total phenolic content and antioxidant capacity contents significantly increased in the infested fruits of the cultivar ‘Istrska belica’. Total phenolic content in the pierced tissue of damaged fruits increased by 10.7%, while the content of AC in the non-pierced tissue of damaged fruits increased by 7.11% and in the pierced tissue of damaged fruits by 6.1% compared to control. A total of 44 individual phenolic compounds were identified, 21 of them increased in at least one cultivar after infestation. Huge increases in phenolic content were observed in both cultivars, particularly for flavones, secoiridoids, anthocyanins, and flavonols in the pierced tissue of damaged fruits. The most responsive individual phenolic compound in both cultivars was oleuropein. Its content in the pierced tissue of damaged fruits increased by 44.7% in the cultivar ‘Pendolino’ and for 82.6% in the cultivar ‘Istrska belica’. pests brown marmorated stink bug Halyomorpha halys olive fruits phenolics metabolic response fruit quality olive orchard škodljivci rastlin marmorirana smrdljivka fenoli presnovni odziv kakovost sadja oljka oljčni nasad true false true Angleški jezik Slovenski jezik Članek v reviji 2022-09-21 11:44:11 2022-09-21 11:44:15 2024-02-17 03:54:16 0000-00-00 00:00:00 2022 0 0 14 str. iss. 9, art. 2200 Vol. 12 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 634.1/.7 2073-4395 10.3390/agronomy12092200 122264067 agronomy-12-02200-v2.pdf agronomy-12-02200-v2.pdf 1 925BD599AFB8B83D2F4D67CF28E53820 fe5fe7057c5cadac8755bb28e87c348df9848ed0b5ce68adbb4da11cf42063a1 5960d0ca-ccb6-11ee-9559-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180936 https://www.mdpi.com/2073-4395/12/9/2200 1 e15f96b3-3991-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=161773 Biotehniška fakulteta 0 0 0
