Resumo: Characteristics of food quality can affect the health of consumers and are influenced by several factors including the system of production. Lettuce has the highest sales volume of any leafy vegetable sold in Brazil and is considered a good source of vitamins, minerals and other compounds. This study aimed to determine the influence of the type of production system (conventional, organic and hydroponic) on the physical and chemical characteristics of two lettuce cultivars. Experiments were conducted simultaneously for each production system using a completely randomized design with three repetitions and two lettuce cultivars (Rubra and Crystal). Subsequently, a joint analysis of the three experiments was performed and averages compared by a Tukey test at 5%. The following characteristics were evaluated: number of leaves, plant height, plant diameter, stem diameter, the fresh weight and dry weight of roots and plants, instrumental color, pH, titratable acidity, total soluble solids, the ratio of soluble solids to titratable acidity and moisture content. It was concluded that the type of production system does affect attributes of lettuce quality with distinctions between cultivars. The most intense distinctions were found under the hydroponic system.

A alface é a hortaliça folhosa mais comercializada no Brasil e considerada fonte de vitaminas, sais minerais e outros compostos. O objetivo do presente trabalho foi estudar a influência de sistemas de produção (orgânico, convencional e hidropônico) nas características físicas e químicas de duas cultivares de alface. Foram conduzidos simultaneamente três experimentos, um em cada sistema de produção em delineamento experimental inteiramente ao acaso com três repetições e duas cultivares de alface (Rubra e Cristal). Posteriormente, uma análise conjunta dos três experimentos foi realizada e as médias submetidas ao teste de Tukey com 5% de probabilidade. As seguintes características foram avaliadas: número de folhas, altura deplantas, diâmetro de planta e de caule, peso fresco e massa seca de raízes e plantas, cor instrumental, pH, acidez titulável, sólidos solúveis totais, ratio e umidade. Concluiu-se que há influência dos sistemas de produção em atributos de qualidade da alface de maneira distinta entre as cultivares com maior intensidade do sistema de produção hidropônico.EDUFU2017-05-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3654610.14393/BJ-v33n3-36546Bioscience Journal ; Vol. 33 No. 3 (2017): May/June; 621-630Bioscience Journal ; v. 33 n. 3 (2017): May./June; 621-6301981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/biosciencejournal/article/view/36546/20320Brazil; ContemporaryCopyright (c) 2017 Luma Moreira Martins, Ernani Clarete da Silva, Lanamar de Almeida Carlos, Leila de Castro Louback Ferraz, Gabriel Mascarenhas Maciel, Jéssica Lorena Cruzhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMoreira Martins, Lumada Silva, Ernani ClareteCarlos, Lanamar de Almeidade Castro Louback Ferraz, LeilaMaciel, Gabriel MascarenhasCruz, Jéssica Lorena2022-02-15T20:46:04Zoai:ojs.www.seer.ufu.br:article/36546Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-15T20:46:04Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
