“…NAR indicates the efficiency of the assimilatory system involved in dry matter production, estimating thus the net photosynthesis in this case, the highest NAR value was detected in plants kept under 50% I (Table 3), due to the better use of the supplied mineral elements. This results agree with those in studies developed in hydroponic systems with varying elements in the nutrient solution, including the studies of David et al (2007), Alves (2008) and David and Boaro (2009), emphasizing that this comparison was done among plants of different species.…”

"Araticum-de-terra-fria" (Annona emarginata (Schltdl.) H. Rainer) has been consider a good alternative in rootstock production for the main commercial Annonaceae species. Although this species develops in different soil and climate conditions, there is no understanding by the physiological responses of this species at different nutritional levels. Thus, the objective of this study was to evaluate the influence of different ionic strengths on development of vegetative species known as "Araticum-de-terra-fria". It was evaluated in seedlings grown in different ionic strengths (25% I, 50% I, 75% I and 100% I) of the complete nutrient solution Hoagland and Arnon (1950) nº 2, for 140 days, the following characteristics: Gas Exchange (CO2 assimilation rate, stomatal conductance, internal CO2 concentration, transpiration rate, water use efficiency, Rubisco carboxylation efficiency); Vegetative growth characteristics (diameter, leaf number, dry matter); Physiological Indexes (leaf area ratio, specific leaf area, relative growth rate, net assimilation rate, leaf weight ratio) and Ionic Accumulation (nutrients leaf analysis). Seedlings grown under 50% I showed the highest values of Leaf CO2 assimilation rate, water use efficiency, carboxylation efficiency, growth, relative growth rate, net assimilation rate and ionic accumulation in the total dry matter. So it is concluded that "Araticum-de-terra-fria" seedlings grown under intermediate nutrient concentrations of complete nutrient solution Hoagland and Arnon (1950) nº 2, explored more adequately their physiological potential that justify their adaptation in different nutritional conditions and allow reducing the amount of mineral nutrition of seedlings production.

“…However, these plants that showed no great differences in CO 2 assimilation, revealed adequated exports from leaves to branches and petioles, as demonstrated by the evaluation of leaf mass ratio, and confirmed by the distribution of dry mass of branches and petioles (David and Boaro, 2009). Then, the amount of this nutrient offered was adequate, once these plants showed normal growth, with no interference in the translocation of carbohidrates to other organs.…”

Mentha piperita L. is an aromatic and medicinal species of the family Lamiaceae, known as mint or peppermint, and its leaves and branches produce essential oil rich in menthol. This study aimed to evaluate physiological indexes, macro-and micronutrients inthe shootsand essential oil of Mentha piperita L. grown in nutrient solution number 2 of Hoagland and Arnon (1950) with different N, P, K and Mg levels. Shoot length, dry mass of the different organs, total dry mass, leaf area, essential oil yield and composition, and macronutrient (N, P, K, Mg, Ca, S) and micronutrient (Mn, Cu, Fe, Zn) contents in the shoot were evaluated. Plants treated with 65%N/50%P/25%K/100%Mg had a tendency towards longer shoot, greaterroot and leaf blade dry masses, higher essential oil yield, higher menthol levels and lower menthone levels. The results showed that Mentha can be grown in nutrient solution by reducing 65% N, 50% P, 25% K and 100% Mg. This solution had better development compared to the other tested treatments. Therefore,we recommendMentha piperita L. to be grown with such nutrient levels.Keywords: Lamiaceae, menthol,hydroponics and nutrition RESUMO: Índices fisiológicos, macro e micronutrientes no tecido vegetal e óleo essencial de Mentha piperita L. cultivada em solução nutritiva com variação de N, P, K e Mg. Mentha piperita L., é uma espécie aromática e medicinal pertencente à família Lamiaceae, conhecida como menta ou hortelã-pimenta que produz em sua parte aérea óleo essencial rico em mentol. O objetivo do trabalho foi avaliar os índices fisiológicos, macro e micronutrientes na parte aérea e óleo essencial de Mentha piperita L. cultivada em solução nutritiva numero Hoagland e Arnon (1950) com variação dos níveis de N, P, K e Mg. Foram avaliados comprimento da parte aérea, massa seca dos diferentes órgãos e total, área foliar, rendimento e composição do óleo essencial, teor de macronutrientes (N, P, K, Mg, Ca e S), e de micronutrientes (Mn, Cu, Fe e Zn) na parte aérea. As plantas nutridas com 65% de N, 50% de P, 25% de K, e 100% de Mg, apresentaram tendência de maior comprimento de parte aérea e massa seca de raízes e de lâminas foliares; maior rendimento de óleo essencial e, em média, maiores teores de mentol e menores teores de mentona. O resultados permitem concluir que a Mentha pode ser cultivada em solução nutritiva reduzindo-se 65% de N, 50% de P, 25% de K e 100% de Mg. Esta solução apresentou melhor desenvolvimento em relação aos outros tratamentos. Recomenda-se, portanto, o cultivo da Mentha piperita L. com tais níveis de nutrientes.
