Qualitative performance of lettuce cultivars in four seasons in Mossoró, Rio Grande do Norte State, Brazil

Abstract: RESUMOThe major challenge in producing good quality lettuce in the semiarid region is the climatic factors such as high temperature, high luminosity and low air relative humidity, which affect the quality characteristics of leafy vegetables. Thus, the objective of this study was to evaluate the quality of lettuce cultivars of Crisphead (Angelina, Amelia and Taina), Mimosa (Mila, Mimosa and Lavinia), Green-leaf (Scarlet, Vera, Isabella and Vanda) and Loose-leaf (Elisa and Regiane) in four seasons: summer (12/21… Show more

“…Despite the significant effect of cultivars, the Tukey's test showed no differences between the means of SS in the cultivars, which presented an overall mean of 4.72 °Brix (Table 4). SS contents are responsible for the sweet flavor of the food and can be affected by climatic and genetic factors (SILVA et al, 2016). Vicentini-Polette et al ( 2018) found a mean SS of 2.6 °Brix for the lettuce cultivar Crocantela grown in hydroponic system, which is lower than that found in the present study.…”

“…Seu cultivo é caracterizado pela produção familiar em áreas pequenas, tornando-a mais importante ainda, pois é responsável por gerar renda e fixar o agricultor no campo, gerando em torno de cinco empregos diretos por hectare (ZÁRATE et al, 2010;ALENCAR et al, 2012). No Estado do Rio Grande do Norte, a produção de alface é baixa quando comparada com outras regiões do país, principalmente devido a elevadas temperaturas e luminosidades que associadas a cultivares com baixa adaptação a essas condições resultam em baixo desempenho produtivo (SILVA et al, 2016).…”

“…Tais resultados podem estar diretamente relacionados à melhor aceitação pelos consumidores quanto ao sabor da alface no teste sensorial. Valores superiores a este trabalho foram observados por Silva et al (2016) para cultivar Vanda que apresentou variação de 3,8 a 5,44 ºBrix em função da época de plantio. De acordo com Freire et al (2009), o teor de sólidos solúveis totais é fortemente influenciado por fatores ambientais como condições de clima, temperatura e tipo de cultivar.…”
