Resumo: Early leaf yellowing in cut alstroemeria (Alstroemeria aurantiaca) flowers before flower development and petal abscission is an important limiting postharvest quality and vase life factors. Early leaf senescence reduces postharvest longevity of cut flowers and promotes petal's wilting. A study was made to evaluate the response of cut alstroemeria flowers at varying concentrations of cycloheximide (CHI) (50, 100 and 200 mg l-1), coconut water (5, 10 and 20%) and 6-benzyladenine (BA) (50, 100 and 200 mg l-1). CHI, coconut water and BA extended the vase life at all concentrations compared to the control, but coconut water at 5% concentration (with 17.39 days) was the most effective treatment. Control cut flowers showed the least vase life (10.76 days). Ethylene production in cut flowers promoted flower senescence. All concentrations of CHI, coconut water and BA delayed ethylene production compared to the control. Treatment of cut flowers with coconut water at concentration of 5% maintained the highest fresh weight of flowers and increased the content of water uptake. The chlorophyll degradation was significantly reduced by the application of CHI, coconut water and BA. The maximum content of membrane's lipid peroxidation and antioxidant enzymes activity (super oxide dismutase and peroxidase) was obtained in control cut flowers. Thus, 5% fresh coconut water has the potential to be applied as vase solution (preservative medium) due to prolongs of cut alstroemeria flowers.

A senescência precoce da folha reduz a longevidade pós-colheita das flores cortadas e promove o murchamento da pétala. Um estudo foi realizado para avaliar a resposta de flores de alstroemeria cortadas em diferentes concentrações de cicloheximida (CHI) (50, 100 e 200 mg l-1), água de coco (5, 10 e 20%) e 6-benziladenina (BA) 50, 100e 200 mg l-1). CHI, água de coco e BA prolongou a vida do vaso em todas as concentrações em comparação com o controle, mas a água de coco a 5% de concentração (com 17,39 dias) foi o tratamento mais eficaz. As flores cortadas de controlo mostraram a menor vida útil do vaso (10,76 dias). A produção de etileno em flores cortadas promoveu a senescência da flor. Todas as concentrações de CHI, água de coco e BA atrasaram a produção de etileno em comparaçãocom o controle. O tratamento de flores cortadas com água de coco a uma concentração de 5% manteve o maior peso fresco de flores e aumentou o conteúdo de absorção de água. A degradação da clorofila foi significativamente reduzida pela aplicação de CHI, água de coco e BA. O teor máximo de atividade de enzimas antioxidantes e de peroxidação lipídica da membrana (super óxido dismutase e peroxidase) foi obtido em flores cortadas de controle. Assim, 5% de água de coco fresca tem potencial para ser aplicada como solução de vaso (meio de conservação) devido a prolongamentos das flores de alstroemeria cortadas.EDUFU2017-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3438110.14393/BJ-v33n2-34381Bioscience Journal ; Vol. 33 No. 2 (2017): Mar./Apr.Bioscience Journal ; v. 33 n. 2 (2017): Mar./Apr.1981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/34381/19998Matak, Saeedeh AlizadehHashemabadi, DavoodKaviani, Behzadinfo:eu-repo/semantics/openAccess2021-05-31T22:12:06Zoai:ojs.www.seer.ufu.br:article/34381Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2021-05-31T22:12:06Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
