Resumo: | Lettuce is the most important leafy vegetable in Brazil. Hydroponic lettuce cultivation has grown due to the viability of harvesting throughout the year. In this context, this study aimed to evaluate the agronomic characteristics, color, and preference of curly lettuce in the NFT hydroponic system. Six lineages (6601-1A, 6601-2L, 7016-6A, 7119-1B, 7223-1A, and 7224-4A) and two commercial cultivars (Brida and Vanda) of lettuce were used, in a completely randomized blocks design with four replications. Shoot length, root length, stem length, number of leaves, stem diameter, plant diameter, shoot fresh mass, root fresh mass, chlorophyll content, instrumental color, and sensory characteristics were evaluated. As for agronomic evaluation, the bolting of 6601-2L lettuce was relevant in different attributes. The Vanda lettuce and the lineage 7016-6A presented best performances for shoot fresh mass (399.44 and 378.63 g, respectively), while the lineages 7119-1B and 6601-2L present the worst performance (279.50 and 273.13 g, respectively). There was variation in chlorophyll content and luminosity, however, the evaluators did not notice differences between lettuces for brightness or green color, as well as for crunchy texture. Lettuces 6601-2L, 7224-4A, 6601-1A, Brida, 7223-1A, and 7119-1B were preferred. The variation among plants may be due to different situations, such as harvesting times and bolting, and a direct relationship between agronomic properties and preference among lettuces has not been established yet. |

O cultivo hidropônico de alfaces tem tido crescimento pela viabilidade de colheita durante todo o ano. Objetivou-se avaliar as características agronômicas, coloração e preferência de alface crespa no sistema de cultivo hidropônico NFT. Foram utilizadas seis linhagens de alface e dois cultivares comerciais. Avaliaram-se as medidas de comprimento de parte aérea, de raiz e de caule, diâmetro do caule e da planta, massa fresca da parte aérea e da raiz, número de folhas, teor de clorofila, coloração instrumental e características sensoriais. Quanto à avaliação agronômica, o pendoamento da alface 6601-2L mostrou-se relevante em diferentes atributos. Para comprimento de raiz as alfaces 7223-1A e 7224-4A (37 e 39 cm) se destacaram positivamente dos demais. A alface Vanda, mesmo apresentando o menor comprimento de raiz apresentou um dos melhores desempenhos para massa fresca de parte aérea. O menor comprimento de caule encontrado foi 6,41 cm (6601-1A). Houve variação quanto ao teor de clorofila e à luminosidade – porém, os avaliadores não perceberam diferenças entre as alfaces para o brilho nem para cor verde, assim como para textura crocante. As alfaces 6601-2L, 7224-4A, 6601-1A, Brida, 7223-1A e 7119-1B foram as preferidas. A variação entre as plantas pode ser devido a diferentes situações, tais como tempo de colheita e pendoamento, não estabelecendo-se ainda uma relação direta entre as propriedades agronômicas e a preferência entre as alfaces.EDUFU2021-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/5376510.14393/BJ-v37n0a2021-53765Bioscience Journal ; Vol. 37 (2021): Continuous Publication; e37074Bioscience Journal ; v. 37 (2021): Continuous Publication; e370741981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/53765/32918Brazil; Contemporary Copyright (c) 2021 Jean Jefferson de Sá, Carolina Medeiros Vicentini-Polette, Marta Regina Verruma-Bernardi, Marta Helena Fillet Spoto, Fernando César Salahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessJefferson de Sá, JeanMedeiros Vicentini-Polette, CarolinaVerruma-Bernardi, Marta ReginaFillet Spoto, Marta Helena Sala, Fernando César2022-02-25T18:22:07Zoai:ojs.www.seer.ufu.br:article/53765Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-25T18:22:07Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
