Resumo: | The quality and the profitability on floriculture are intimately linked to the adequate plant nutrition. In the present research we aimed to evaluate the electrical conductivity (EC) and pH of the substrate solution on four different gerbera cultivars subjected to fertigation, with two nutritive solutions. The experiment was carried out in a greenhouse, from May to July 2006, on the Universidade Estadual Paulista, Botucatu, São Paulo state, Brazil. The experiment was carried out under an experimental design of random blocks, in 4×2 factorial arrangement, with four Gerbera cultivars (Cherry, Golden Yellow, Salmon Rose and Orange) and two nutritive solution concentrations: 0.92 and 1.76 dS m-1 EC) during the vegetative stage, and 1.07 and 2.04 dS m-1 during the reproductive stage (S1 and S2, respectively). The nutrients were applied through fertigation, manually performed every day. The EC and pH values of the substrate solution were evaluated weekly, using the 'pourthru' method. Orange and Cherry cultivars had, respectively, the highest and the lowest electrical conductivity of the substrate solution, and Cherry was the most efficient on the nutrient uptake. The solution S2 showed a trend to accumulate salts in the substrate, but without visual symptoms of plant toxicity, leading to the lowest pH values. The 'pourthru' method was efficient when compared to the 1:2 method and can be adopted for substrate solution analysis in gerbera culture. |

O presente trabalho teve por objetivo avaliar a condutividade elétrica e o pH da solução do substrato em quatro diferentes cultivares de gérbera fertirrigadas com duas soluções nutritivas. O experimento foi conduzido em casa de vegetação, de maio a julho de 2006, na Universidade Estadual Paulista, em Botucatu-SP. O mesmo foi instalado sob delineamento experimental em blocos casualizados em esquema fatorial 4×2, sendo quatro cultivares de gérbera (Cherry, Golden Yellow, Salmon Rose e Orange) e duas concentrações de solução nutritiva com condutividade elétrica de 0,92 e 1,76 dS m-1 no período vegetativo, e 1,07 e 2,04 dS m-1 no período reprodutivo (S1 e S2, respectivamente). Os nutrientes foram aplicados via fertirrigação, realizada manualmente, uma vez ao dia. Semanalmente avaliou-se a condutividade elétrica e pH da solução do substrato utilizando a metodologia do 'pourthru'. A solução do substrato nas cultivares Orange e Cherry apresentou maior e menor condutividade elétrica, respectivamente, e Cherry foi a mais eficiente na absorção de nutrientes. A solução 2 apresentou tendência de acúmulo de sais no substrato, mas sem sintomas visuais de fitotoxidez e, nesta solução foram registrados os menores valores de pH. A metodologia do 'pourthru' mostrou-se eficiente quando comparada ao método de diluição 1:2 e pode ser adotada para análise da solução do substrato na cultura da gérbera.UNESP FCA Depto Recursos NaturaisUFPI CCA Depto Eng.
