20.500.12556/RUL-189577 The effect of some treatments with mitigated frost damage on mango trees under desert soil conditions Učinek nekaterih obravnavanj za zmanjšanje škode po zmrzali na drevesih manga v razmerah puščavskih tal The present study was carried out during the 2024 and 2025 seasons on 10-year-old ‘Naomi’ mango cultivar trees grown in an orchard located on Abo Ghaleb Road, Egypt. In this study, we examine the effects of foliar sprays of salicylic acid at (5, 10, and 20 gl-1), potassium silicate at (15, 30, 45 ml l-1), glycine betaine at (7.5, 15 and 30 g l-1) and mono-potassium phosphate at (0.01, 0.02 and 0.04 g l-1) foliar spraying in mid-November, December and January. Leaf area, chlorophyll content (SPAD reading), macro- and micronutrient levels in leaves, yield, and fruit characteristics were used to assess the influence. The results indicated that all spray treatments yielded the best results in terms of leaf area, proline, and leaf chlorophyll content, while improving the yield and quality characteristics of ‘Naomi’ mango fruits compared to the control in both seasons. Glycine betaine (GB) at 15 g l-1, followed by potassium silicate (KS) at 15 ml l-1 outperformed all other spray treatments and recorded the highest values across all studied characteristics. Finally, treatments have increased the trees’ tolerance to frost stress; it is advisable to apply them as an agronomic practice in mango trees grown under frost stress. salicylic acid potassium silicate glycine betaine mono-potassium phosphate frost stress mango leaf mineral nutrients fruit quality salicilna kislina kalijev silikat glicinbeatin monokalijev fosfat stres zaradi zmrzali mango listna mineralna hranila kakovost sadja true false true Angleški jezik Slovenski jezik Članek v reviji 2026-10-09 11:19:53 2026-10-09 11:19:58 2026-10-10 04:29:38 0000-00-00 00:00:00 2026 0 0 12 str. no. 3 Vol. 122 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 631 1854-1941 10.14720/aas.2026.122.3.27822 294442243 Abd+El-Rhman+et+al.+(A)_(1).pdf Abd+El-Rhman+et+al.+(A)_(1).pdf 1 7806E1ACD5092621CD9CAEC0B939400C 28a55ae747fd068139718fc4de86ed2556f1005031545f0d15f9734427ed8221 c436c85e-c3c2-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=250227 https://journals.uni-lj.si/aas/article/view/27822/22588 1 786ec554-c3c2-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=250226 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
