Resumo: | The objective of this research was to determine the levels of chlorophyll and vitamin-C in the cultivars of lettuce (Elba, Cristina and Veneranda) in the hydroponic system with nutrient solutions with different levels of salinity. The experiment was conducted at the State University of Paraíba,UEPB Campus-II, rural area of the city of Lagoa Seca-PB, using the Laminar Flow of Nutrients-NFT technique in a protected environment. The experimental design was in randomized blocks, in a subdivided plot scheme, the plots consisting of seven nutrient solutions prepared from the Furlani methodology so that solution S1 presented Electric conductivity-EC (1.9 dS m-1) and the other solutions, EC values: S2-2.4; S3-2.9; S4-3.4; S5-3.9; S6-4.4 and S7-4,9 dS m-1, with three repetitions. The subplots composed of the cultivars Elba, Cristina and Veneranda. Variables analyzed: levels of total chlorophyll (Chl a and b), carotenoids and vitamin-C. The nutritional solutions showed linear behavior for all treatments, not differing statically from each other. The highest value for total chlorophyll was obtained in the cultivar Veneranda. For the variables (Chl b and total) the highest levels were found in the cultivar Veneranda whose values 35.97 and 52.06 mg g-1 respectively. The treatment Elba/S3=3.4 dS m-1 provided the highest average carotenoid content of 57 mg g-1, yet the cultivar Elba showed the highest levels (Chl a) with nutrient solutions S2=2.4 and S3=3.9 dS m-1. The cultivar Veneranda promoted the highest levels for (Chl b and total). The highest levels of vitamin-C were found in the cultivars Cristina and Veneranda. |

El experimento se realizó en la Universidad Estatal de Paraíba,UEPB Campus-II, área rural de la ciudad de Lagoa Seca-PB, la técnica de Flujo Laminar de Nutrientes-NFT en ambiente protegido. El diseño experimental en bloques aleatorios, esquema de parcelas subdivididas, las parcelas consistieron soluciones nutritivas preparadas a partir la metodología Furlani, de manera que la solución S1 presentó Conductividad eléctrica-CE (1.9 dS m-1) y las otras soluciones con CE: S2-2.4; S3-2.9; S4-3.4; S5-3.9; S6-4.4 y S7-4.9 dS m-1, con tres repeticiones, las subparcelas compuestas los cultivares Elba, Cristina y Veneranda. Variables analizadas fueron: niveles de clorofila total, Chl a, b, carotenoides y vitamina-C. Las soluciones nutricionales mostraron un comportamiento lineal para todos los tratamientos, no difiriendo estáticamente entre sí. El mayor valor de clorofila total se obtuvo en el cultivar Veneranda. Para las variables (Chl b y total) los niveles más altos se encontraron en el cultivar Veneranda, cuyos valores fueron 35.97 y 52.06 mg/g-1 respectivamente. El tratamiento Elba/S3=3.4 dS m-1 proporcionó el contenido promedio de carotenoides más alto de 57 mg/g-1, sin embargo, el cultivar Elba mostró los niveles más altos (Chl a) con soluciones nutritivas S2=2.4 y S3=3.9 dS m-1. El cultivar Veneranda promovió los niveles más altos para (Chl b y total). Los niveles más altos de vitamina-C se encontraron en los cultivares Cristina y Veneranda.O objetivo desta pesquisa foi determinar os teores de clorofila e vitamina-C nas cultivares da alface (Elba, Cristina e Veneranda) cultivadas em sistema hidropônico com soluções nutritivas apresentando diferentes níveis de salinidade. O experimento foi conduzido na Universidade Estadual da Paraíba,UEPB Campus-II, zona rural da cidade de Lagoa Seca-PB, via técnica Fluxo Laminar de Nutrientes-NFT em ambiente protegido. O delineamento experimental foi em blocos casualizados, em esquema de parcelas subdivididas, as parcelas constituídas por sete soluções nutritivas preparadas a partir da metodologia de Furlani de modo que a solução S1 apresentou Condutividade Elétrica-CE (1,9 dS m-1) e as demais soluções os seguintes valores de CE: S2-2,4; S3-2,9; S4-3,4; S5-3,9; S6-4,4 e S7-4,9 dS m-1, com três repetições. As subparcelas foram compostas pelas cultivares Elba, Cristina e Veneranda. As variáveis analisadas foram: teores de clorofila (Chl a e b) total, carotenoides e vitamina-C. As soluções nutritivas apresentaram comportamento linear para todos os tratamentos não deferindo estaticamente entre si. O maior valor para clorofila total foi obtido na cultivar Veneranda. Para as variáveis (Chl b e total) os maiores teores encontrados foi na cultivar Veneranda, cujos valores foram de 35,97 e 52,06 mg/g-1 respectivamente. O tratamento Elba/S3=3,4 dS m-1 proporcionou o maior teor de carotenoides média de 57 mg/g-1, ainda a cultivar Elba apresentou os maiores teores (Chl a) com as soluções nutritivas S2=2,4 e S3=3,9 dS m-1.

The nutritional solutions showed linear behavior for all treatments, not differing statically from each other. The highest value for total chlorophyll was obtained in the cultivar Veneranda. For the variables (Chl b and total) the highest levels were found in the cultivar Veneranda whose values 35.97 and 52.06 mg g-1 respectively. The treatment Elba/S3=3.4 dS m-1 provided the highest average carotenoid content of 57 mg g-1, yet the cultivar Elba showed the highest levels (Chl a) with nutrient solutions S2=2.4 and S3=3.9 dS m-1.
