20.500.12556/DiRROS-31350 Ethephon role in maize yield and lodging through plants morphological and chemical changes Uloga etefona u prinosu i poleganju kukuruza kroz morfološke i hemijske promene biljaka Ethephon, a plant growth regulator that releases ethylene, has emerged as a pivotal tool for improving maize performance under diverse growing conditions. This review synthesizes existing findings on ethephon’s role in modulating maize architecture that strongly influence lodging resistance and yield as well as nitrogen uptake. When applied at strategic growth stages and optimal doses between 280 and 840 g ha⁻¹, ethephon consistently strengthens stalks, lowers the center of gravity, and mitigates lodging risks, particularly under high-density planting. Although some studies report yield reductions when lodging threats are minimal, others demonstrate considerable yield gains up to 200% under drought and stress conditions, largely by redirecting assimilates toward reproductive structures and enhancing physiological resilience. Ethephon also interacts synergistically with other growth regulators, augmenting stem diameter, lignin deposition, and root anchorage. However, responses vary with genotype, environmental factors, and cultural practices, underscoring the importance of tailored application protocols. Collectively, the evidence points that its integration into maize production systems, especially where lodging pressures and water limitations prevail, offers both agronomic and economic benefits. Although numerous studies have clarified above-ground changes, the impact of ethephon on maize root architecture and nutrient uptake remains largely underexplored. Further refinement of dose–response relationships across diverse germplasm, planting densities, and nitrogen management regimes is essential to develop precise, context-specific guidelines. Systematic screening of hybrids will clarify genotype-byethephon interactions, guiding breeders in selecting lines with stable yield and improved lodging tolerance. Combining ethephon with other PGRs besides mostly used diethyl aminoethyl hexanoate should be studied. maize maize yield ethephon growth hormones lodging Aspergillus Chrysoperla carnea Fusarium Trichogramma brassicae true false true Angleški jezik Srbski jezik (cirilica) Neznano 2026-07-29 12:34:58 2026-07-29 12:34:58 2026-07-30 03:49:46 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Soavtorji: Goran Bekavac, Božana Purar, Anja Đurić, Maja Tanasković; Opis vira z dne 22. 7. 2026; Povzetek v srbskem jeziku na koncu članka; str. 53-68 no. 1 Vol. 63 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-03-31 632 2217-8392 10.5937/ratpov63-62729 285690883 1821-39442601053D.pdf 1821-39442601053D.pdf 1 846A6BB715D029D98AF919E1D41A2AF2 aab01f6764d97b606b1b18282353e2d907f08af043ccbba8a1f770f74e8b4eae 26979ec0-8b39-11f1-923b-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=48499 RAZ_Dunderski_Dusan_2026.pdf RAZ_Dunderski_Dusan_2026.pdf 1 FCE9DB1FADC1803519D72A3D727D91EA 6f9ee1710945405db15705d4b130a8745cb849d3e6240aac47d3aef5502a2b9a 3db71e6f-8b39-11f1-923b-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=48500 Kmetijski inštitut Slovenije 0 0 0
