20.500.12556/RUL-135025 Physiological and biochemical responses of ungrafted and grafted bell pepper plants (Capsicum annuum L. var. grossum (L.) Sendtn.) grown under moderate salt stress The response of grafted bell pepper plants (Capsicum annuum L. var. grossum (L.) Sendtn.) to salt stress was investigated by analyzing the photosynthetic traits and mineral content of the plants and the metabolic composition of the fruit. The bell pepper variety “Vedrana” was grafted onto the salt-tolerant rootstock “Rocal F1” and grown at two salinities (20 mM and 40 mM NaCl) and control (0 mM NaCl) during the spring–summer period. On a physiological level, similar stomatal restriction of photosynthesis in grafted and ungrafted plants indicated that grafting did not alleviate water balance disturbances under increased salt exposure. Measurements of midday water potential did not show improved water status of grafted plants. The similar metabolic changes in grafted and ungrafted plants were also reflected in similarly reduced fruit yields. Thus, this grafting did not reduce the risk of ionic and osmotic imbalance in pepper plants grown under moderate salt treatment. Changes in the biochemical profiles of the pepper fruit were seen for both added-salt treatments. The fruit phenolic compounds were affected by rootstock mediation, although only for the July harvest, where total phenolics content increased with 40 mM NaCl treatment. Fruit ascorbic acid content increased with the duration of salt stress, without the mediation of the rootstock. The high salt dependence of this quality trait in pepper fruit appears to lead to more limited rootstock mediation effects. grafting ascorbic acid phenolics NaCl photosynthetic traits proline Capsicum annuum L. paprika slanostni stres cepljena paprika fenolne spojine askorbinska kislina fiziologija rastlin biokemija rastlin true false true Angleški jezik Slovenski jezik Članek v reviji 2022-02-17 15:30:26 2022-02-17 15:30:26 2022-09-14 04:11:15 0000-00-00 00:00:00 2021 0 0 19 str. iss. 2, art. 314 Vol. 10 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 581 2223-7747 10.3390/plants10020314 50629891 RAZ_Kacjan-Marsic_Nina_2021.pdf RAZ_Kacjan-Marsic_Nina_2021.pdf 1 468DFFFFA9B2480299C9F84280DEB419 e4613f803b08809b68756d21216dcfcbfd4a63a0dea33c8314d95b173c01bac3 34021a95-8ffe-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153852 https://www.mdpi.com/2223-7747/10/2/314 0 e81b0ff1-8ffd-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153851 Biotehniška fakulteta 0 0 0
