Resumo: The aim of this work was to evaluate morphological and anatomical alterations in leaves of ‘Yellow Terrazza’® and ‘Red White Terrazza’® pot roses sprayed with paclobutrazol (0, 40, 60, 80 mg L-1) and daminozide (0, 2000, 4000, 6000, 8000 mg L-1). The experiments were conducted under greenhouse conditions using a factorial treatment design (cultivars x growth retardant doses) with five replications and experimental units arranged in randomized blocks. Cv. Yellow Terrazza ® presented higher plants, greater floral diameter and leaf area than cv. Red White Terrazza ®. Plant height, leaf area, and flower diameter decreased linearly with paclobutrazol and daminozide doses. In addition, paclobutrazol and daminozide applications changed leaf tissue proportions by increasing the thickness of leaf blade, mesophyll, palisade parenchyma, and spongy parenchyma but did not influence the thickness of leaf epidermis.

Os experimentos foram conduzidos em ambiente protegido e os tratamentos dispostos em esquema fatorial (cultivares x doses dos retardantes), em delineamento de blocos casualizados com cinco repetições. A cultivar Yellow Terrazza® apresentou plantas com maior altura, diâmetro floral e área foliar que a Red White Terrazza®. O aumento da dose dos retardantes nas duas cultivares reduziu altura e área foliar, promoveu mudanças na proporção dos tecidos, aumentou a espessura da lâmina foliar, mesofilo e dos parênquimas paliçádico e lacunoso. Os retardantes não influenciaram a espessura das epidermes das cultivares. O tecido parenquimático das cultivares apresenta plasticidade com aplicação dos retardantes.UEL2017-11-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de CampoPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2842410.5433/1679-0359.2017v38n6p3481Semina: Ciências Agrárias; Vol. 38 No. 6 (2017); 3481-3490Semina: Ciências Agrárias; v. 38 n. 6 (2017); 3481-34901679-03591676-546Xreponame:Semina.
