“…According to Furlani et al (1999), pH ranging from 4.5 to 7.5 does not compromise the plant growth in hydroponic systems, however, under acidic condition (below 4.0) may compromise the integrity of the cell membrane. Moreover, in alkalinity situations (above 8.0) symptoms of nutrient deficiency, such as phosphorus, may occur.…”

“…The increase in sodium content in the shoots, regardless of the WCET used, is a response to the source of salts used for the nutrient solution preparation (sodium chloride), which increased the salt concentrations in the nutrient solution, possibly influencing the absorption and accumulation of sodium in the shoots. According to Furlani (1999), a greater absorption of nutrients by plants in hydroponics occurs with high concentrations of these nutrients in the nutrient solution.…”

“…According to Furlani (1999), pH values from 4.5 to 7.5 do not affect plant development in hydroponic systems. The pH values of the nutrient solution observed in this study agree with those found by Maciel et al (2012), who studied ornamental sunflower production in NFT hydroponic system under different salinity levels.…”

“…Isso era esperado, visto que, com exceção do Mn, os demais elementos foram fornecidos em quantidades consideradas adequadas para o normal crescimento e desenvolvimento das mudas de caramboleira, segundo Furlani (1999). Freitas (2008) e Rozane (2008), em experimento com mudas de caramboleiras em solução nutritiva de Furlani (1999), encontraram teores de nutrientes superiores, porém muito próximos, aos do presente estudo. As variações observadas podem ser devidas às diferenças nas cultivares, na idade das plantas, na amostragem do tecido e no tempo de cultivo.…”

“…Desdobrando-se as interações para doses, dentro de cada época de coleta, constatam-se incrementos lineares dos teores de manganês e de seu acúmulo (Tabela 2), independentemente da época de coleta e da estrutura avaliada. Na dose de 25 mg L -1 de Mn, as folhas apresentaram teores cerca de 10 vezes maiores que na dose recomendada por Furlani (1999), igual a 0,5 mg L -1 de Mn. Já nas raízes, esse valor foi cerca de 18 vezes mais elevado.…”
