20.500.12556/RUL-189580 Effect of spraying with 5-aminolevulinic acid and nano-zinc oxide on enhancing floral traits of seedlings dwarf pink Bougainvillea ‘Jewel Pink‘ Vpliv škropljenja s 5-aminolevulinsko kislino in nano-cinkovim oksidom na izboljšanje cvetnih lastnosti sadik pritlikave rožnate bugenvilije ‘Jewel Pink’ The research sought to examine the impact of foliar application of 5-Aminolevulinic Acid and Nano-Zinc Oxide on mitigating flower drop, prolonging blooming duration of dwarf pink Bougainvillea ‘Jewel Pink’, in addition to promoting growth characteristics. The experiment included administering four doses of 5-ALA and three concentrations of ZnO-NPs at four separate times. A 4 × 3 factorial experiment was conducted using a RCBD. Means were analysed using the LSD0.05. The results demonstrated that the application of 5-ALA 50 mg l-1 and ZnO-NPs 75 mg l-1 to Bougainvillea seedlings significantly improved flowering characteristics, evidenced by an extended flowering duration and decreased flower drop at multiple intervals compared. Furthermore, there were substantial enhancements in vegetative and root development traits; in contrast, the control treatment (0 mg l-1) had the lowest significant values for both growth metrics. The findings indicated that the concurrent application of 50 mg l-1 5-ALA and 75 mg l-1 ZnO-NPs exhibited considerable superiority in most evaluated growth parameters, with the exception of seedling height, branch diameter, and the length of the longest lateral root. dwarf seedling 5-aminolevulinic ZnO-NPs floral growth pritlikava rožnata bugenvilija okrasne rastline pritlikave sadike 5-aminolevulinska kislina ZnO-NP razvoj cvetov true false true Angleški jezik Slovenski jezik Članek v reviji 2026-10-09 12:08:45 2026-10-09 12:08:52 2026-10-10 04:29:38 0000-00-00 00:00:00 2026 0 0 16 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.2026.122.3.29883 294468611 HUSSAIN+KHALAF+and+ABDULRAZZAQ++(K).pdf HUSSAIN+KHALAF+and+ABDULRAZZAQ++(K).pdf 1 E95F210A49AE27765ACA7E9100FBA395 e6d54870451430ed0ce76b23206b051d7140c9b49b0333a4f13994313674d317 5e92fb35-c3c9-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=250232 https://journals.uni-lj.si/aas/article/view/29883/22603 1 486149ae-c3c9-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=250231 Biotehniška fakulteta Acta agriculturae Slovenica Acta agriculturae Slovenica 0 0 0
