Abstract:The purpose of this paper was to carry out an anatomical and histochemical analysis of the vegetative organs of Cissus verticillata (L.) Nicolson & C.E. Jarvis, Vitaceae, to contribute for the attest the taxonomic identity of the medicinal plant. Samples from root, stem, leaf and tendril were cleared, dissociated and processed according to the usual methodology for observation under light and scanning electron microscopes. Histochemical tests were performed in order to identify polysaccharides, phenolic and lipid compounds. The C. verticillata root is typically protostelic, and the stem is eustelic with collateral bundles. The tendril presents structural organization similar to the stem, suggesting a common origin for both. The petiole has an epidermis with ornamented cuticle; the cortex is composed of collenchyma and parenchyma, and the vascular tissues are arranged in collateral bundles. The leaf blade is amphistomatic with non-glandular and glandular trichomes, and the mesophyll is dorsiventral. The identifi cation of the idioblasts as secretion site of the phenolic compounds, mucilage and terpenoids as being responsible for the potential activity of the plant is of fundamental importance for future bioprospecting research on this species.

“…When observing the growth of phosphorus dose in the production of all secondary metabolites evaluated, it is perceived that there was a decrease in their content and the treatment without adding phosphorus was the best result. Comparing with the results of Abreu et al (2002), Souza et al (2006) and Vieira et al (2015), the results are contrary because they observed an increase in metabolites with increased phosphorus dosage. The accounts of Mapeli et al (2005) and Costa et al (2007) differ more because it did not influence the contents of essential oil.…”

The knowledge of medicinal plants is of great importance for popular health. On the other hand, the levels of secondary metabolites in medicinal plants is an important parameter to be evaluated. The study of the nutrition of plants and the production of metabolites can provide the identification of beneficial factors and also find out if there are harmful effects of this fertilization/nutrition. In this study, three experiments were carried out (nitrogen, phosphate and potassium fertilization) in the culture of Hydrocotyle umbellata L. var. bonariensis (Lam.) Spreng on dystrophic Red Latosol on metabolite production (total phenols, total flavonoids and hibalactone content). It was used the soil of a rural property in the municipality of Anápolis – Goiás (Brazil). The experimental design was completely randomized, in a controlled environment. The experiment involved the following dosages of fertilization: nitrogen (0; 30; 45; 60 e 75 kg of N.ha-1); phosphate (0; 120; 150; 180 e 210 kg of P2O5.ha-1) and potassium (0; 25; 50; 75 e 100 kg of K2O.ha-1). The maximum contents of total phenols were with the medium level of nitrogen, zero level of phosphorous and highest level of potassium. For the total flavonoid, the maximum contents were obtained with the medium levels of nitrogen and potassium and zero level of phosphorus. Finally, the hibalactone content was favored by highest level of nitrogen and zero levels of phosphorus and potassium.

“…To produce the same amount of dry matter, tomatoes leaf required more nitrogen than the stem (Ronchi et al, 2001). In other species, leaf dry matter increase has been observed when the phosphorus supply is increased (Abreu et al, 2002;Rodrigues et al, 2004), which could explain the magnesium thermophosphate effect, because it is an essential component of all organisms. Therefore, its deficit causes biomass decrease (Mapeli et al, 2005).…”

Plant growth is influenced by nutrient availability. The objective of this research was to study, under greenhouse conditions, eggplant growth as affected by rates of bovine manure and magnesium thermophosphate (g kg -1 and mg kg -1 , respectively), according to a "Box central composite" matrix: 4.15-259; 4.15-1509; 24.15-259; 24.15-1509; 0.0-884; 28.3-884; 14.15-0,0; 14.15-1768; 14.15-884. Potassium sulfate (170 mg kg -1 ) and 200 mL per pot of cow urine solution were applied four times, but the concentration of the last two applications (200 mL/H 2 O L) was twice of that of the first two. Additional treatments: magnesium thermophosphate without cow urine and triple superphosphate with urea, both with nutrient levels equivalent to the bovine manure, P 2 O 5 and potassium sulfate to the combination 14.15-884. The experimental design consisted of randomized blocks with four replicates. Leaf area (LA) and LA ratio increased as quadratic functions with manure rates, with negative interaction for thermophosphate. Leaf dry matter mass (DMM) had an increasing quadratic function with rates for both fertilizers. The higher combined rates of both fertilizers resulted in the smallest specific leaf area, but also the highest values of shoot and root DMM, total DMM and, with positive interaction in relation to root shoot dry matter ratio. The relative growth rate in stem height, and also in diameter, increased with manure, according to quadratic and linear functions, respectively. The cow urine effect was, in general, lower than that of urea. The plant's overall growth was more influenced by manure. Root DMM and shoot DMM were greater with high K and P.

O objetivo deste trabalho foi estudar, em abrigo telado, o crescimento da berinjela em função de doses de esterco bovino e termofosfato magnesiano (g kg -1 -mg kg -1 , respectivamente), conforme a matriz "composto central de Box": 4,15-259; 4,15-1509; 24,15-259; 24,15-1509; 0,0-884; 28,3-884; 14,15-0,0; 14,15-1768; 14,15-884. Acrescentaram-se sulfato de potássio (170 mg kg -1 ) e quatro parcelas de 50 mL por vaso de solução de urina de vaca, as duas últimas possuindo concentração de 200 mL L -1 de H 2 O, o dobro da inicial. Tratamentos adicionais: termofosfato magnesiano sem urina de vaca e superfosfato triplo com uréia, iguais em esterco, P 2 O 5 e sulfato de potássio, à combinação 14,15-884. O delineamento experimental foi em blocos casualizados com quatro repetições. A área foliar (AF) e a razão de AF aumentaram, quadraticamente, com as doses de esterco, porém, a interação com o termofosfato foi negativa. A massa de matéria seca (MMS) de folhas incrementou, quadraticamente, com as doses dos dois insumos. Na combinação das maiores doses de ambos ocorreram a menor AF específica e os maiores valores da MMS da parte aére...
