“…O acúmulo médio desse nutriente foi de 17% nos 14 primeiros dias de ciclo, atingindo 48% aos 28 DAE e 90% aos 42 DAE. Em trabalho realizado com três variedades de crisântemo, Ferreira et al (2012) constataram que o acúmulo total de K atingiu seu máximo no fim do ciclo de produção, quando há a abertura completa das inflorescências.…”

A análise de crescimento com base no acúmulo de fitomassa e na marcha de absorção de nutrientes são importantes para determinar as épocas da maior demanda nutricional, de modo a programar a fertirrigação. Assim, esta pesquisa tem como objetivo determinar o crescimento e o acúmulo de nutrientes em plantas de crisântemo desenvolvidas em diferentes níveis de condutividade elétrica (CE) da solução nutritiva. Realizou-se experimento em casa de vegetação, utilizando o delineamento de blocos casualizados com cinco tratamentos e quatro repetições. Os tratamentos corresponderam aos níveis de CE da solução aplicada, com valores de 1,42; 1,65; 1,89; 2,13 e 2,36 dS m -1 (fase vegetativa) e 1,71; 1,97; 2,28; 2,57 e 2,85 dS m -1 (fase de botão). Após o enraizamento das estacas, determinou-se a fitomassa seca da parte aérea e realizou-se a análise química dos macronutrientes e micronutrientes a cada quatorze dias. Os nutrientes tiveram a seguinte ordem de absorção: K>N>Ca>P>Mg>S (1425, 892, 184, 150, 110 e 59 mg planta -1 ) e Fe>Zn>B>Mn>Cu (2254, 2219, 1725, 1287, 210 μg planta -1 ). Grande parte dos nutrientes tem seu teor aumentado com a elevação do nível da CE da solução, sem que haja efeito salino até a CE de 2,85 dS m -1 .Palavras-chave: Dendranthema grandiflora, fertirrigação, análise nutricional, marcha de absorção. Electrical conductivity of nutrient solution on growth and nutrient accumulation in chrysanthemum plants AbstractThe study of growth and uptake of nutrients is important to determine the times of increased demand in order to schedule the fertigation. The present research was developed with the objective of evaluating the effects of different levels of electrical conductivity on growth and accumulation of nutrients in chrysanthemum plants under greenhouse conditions. The electrical conductivity levels on the applied solution were 1.42, 1.65, 1.89, 2.13 and 2.36 dS m -1 (bud vegetative stage); 1.71, 1.97, 2.28, 2.57 and 2.85 dS m -1 (bud stage). The dry mass of the aerial portion of the plant and the contents of macronutrients and micronutrients were determined every 14 days. The nutrient accumulation in chrysanthemum plant showed similar trend as compared to dry matter accumulation. The nutrients presented the following order of absorption: K>N>Ca>Mg>P>S (1425, 892, 184, 150, 110 and 59 mg plant -1 ) and Fe>Zn>B>Mn>Cu (2254, 2219, 1725, 1287 ). The content of most nutrients increased with increase in electrical conductivity of the solution, without salt effect up to EC of 2.85 dS m -1 .

“…Different nutrient demands by cultivars of the same species were observed by Villas Bôas et al (2008) in rose, by Ludwig et al (2013) in gerbera and by Ferreira et al (2012) in chrysanthemum. According to Horn et al (2006) and Rengel & Damon (2008), this difference is due to genetic characteristics and is caused by the variation in the kinetic parameters of nutrient uptake and morphological differences of the root system.…”

Gladiolus is among the most traditional and important cut flowers in Brazil. Silicon (Si) is an element that has increased the production and quality of some ornamental plants. This study aimed at evaluating the production and nutritional status of gladiolus cultivars under greenhouse conditions, according to the Si doses applied to the substrate. The experimental design was randomized blocks, in a 3 x 4 factorial scheme, being three gladiolus cultivars ('White Friendship', 'Rose Friendship' and 'Red Beauty') and four Si doses (0 mg dm-3, 150 mg dm-3, 300 mg dm-3 and 600 mg dm-3), with five replicates. Morphological traits and leaf Si, macro and micronutrients were evaluated. 'White Friendship' and 'Red Beauty' developed taller plants, with a higher diameter and spikes heavier and longer than 'Rose Friendship'. The order of leaf nutrient concentrations for all the cultivars evaluated was the same (K > N > Ca > Mg > S > P > Fe > Mn > B > Zn > Cu), with all of them being classified as Si non-accumulators. Neither the evaluated morphological variables, nor the uptake of the nutrients N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn, were affected by the Si supplementation, suggesting that the addition of Si to the substrate does not enhance the gladiolus production.

The objective was to evaluate the biosolids as an alternative source of nutrients in the production of chrysanthemums by adding increasing doses to the cultivation substrate. The experimental design was in blocks with 6 treatments and 5 replications. The treatments consisted of the mixture (commercial substrate + biosolid) at the concentrations: 20%, 40%, 60% and 80% of biosolid + two controls (100% of biosolid and 100% of substrate). The experiment was conducted in a greenhouse for 90 days. Physiological parameters, number of flower buds, dry biomass and nutrient accumulation were evaluated. Physiological parameters were evaluated using the Infrared Gas Analyzer. The number of flower buds was evaluated by counting. Biomass was determined after drying the structures and then calculated the accumulation of nutrients. A total of 90 plants were evaluated. Concentrations of up to 40% of biosolid promoted a greater number of flower buds, dry biomass and nutrient accumulation. Concentrations above 60% lower number of buds, biomass increment and nutrient accumulation. It is concluded that the biosolid has potential as an alternative source of nutrients in the cultivation of chrysanthemums, indicating concentrations of up to 40% and the nutrient content of each batch generated must be verified.
