“…This decrease may be due to the high electrical conductivity of the enriched biofertilizer (Table 4), which provides high levels of Ca 2+ , Mg 2+ , Na + and Cl - (Cavalcante et al, 2019;Oliveira et al, 2014;Sediyama et al, 2014), and the largest buildup of moisture, provided by the use of all of these techniques together, could have caused a nutritional imbalance, resulting in the absorption of some nutrients in excess, such as Na + and Cl -, which are toxic to plants (Lima et al, 2018). A similar situation was recorded by Corrêa et al (2009), who concluded that high input rates of cow and poultry manure inhibit the production of chlorophyll despite raising the levels of chlorophyll in plants. For these authors, the decreases were attributed to excess nutrients provided by the inputs in the soil solution.…”

“…Rosolem and Leite (2007), for instance, reported decreased mesophyll thickness in plants of Coffea arabica var. Catuaí and Mundo Novo due to boron deficiency, while Corrêa et al (2009) found increased thickness of the leaf blade, palisade parenchyma and spongy parenchyma in oregano plants (Origanum vulgare L.) subjected to increasing doses of organic fertilizer.…”

“…Therefore, the lower nutrient dose, i.e., the one for the lower carrying capacity (7 AU ha -1 ), led to decreased thickness of specialized epidermal cells, which can be explained by the phenotypic plasticity of the studied plants to different environmental conditions and nutrient availabilities. Lower nutrient dose propitiates a different environment for the plant, inducing adjustments in leaf architecture in response to that factor (Corrêa et al, 2009). Thicker, turgid bulliform cells enable the leaf to remain extended, thereby maintaining the plant physiological status more stable.…”

Brazilian agribusiness is heavily influenced by beef export. Thus, it is important to evaluate the quality and growth rate of forage species used as cattle food. Given that the structural organization of leaf cells and tissues is directly related to forage-plant growth, we aimed to analyze the foliar anatomy of Urochloa brizantha and U. ruziziensis subjected to different fertilization management practices. Experimental design was completely randomized split-split-plots. Plots were allocated to fertilization strategies, namely single and split fertilizer application. Subplots were allocated to two fertilizer doses for the carrying capacities of 7 and 10 head of cattle per hectare (AU ha-1). Sub-subplots were distributed to the forage plant species U. brizantha and U. ruziziensis. Three leaves were collected from each treatment for the anatomical processing of cross-sections, epidermal imprints and diaphanizations. Based on a parsimonious model, U. brizantha showed thicker leaf tissues than U. ruziziensis. Split fertilizer application increased thickness of the adaxial and abaxial cuticle and of bulliform cells. Fertilizer dose of the higher carrying capacity determined increased thickness of the leaf blade, bulliform cells, and regular homogeneous parenchyma on both studied species. We concluded that increased fertilizer dose and split application interfere with the leaf anatomy of U. brizantha and U. ruziziensis, providing both species with enhanced growth and yield.

Extracción y caracterización físico-química del aceite esencial de Origanum syriacum L. extraído en diferentes tiempos. Se estudió la composición química del aceite esencial de Origanum syriacum L. -nueva variedad introducida en Paraguay-extraído a las 2, 4 y 6 horas del proceso respectivamente, por el método de destilación por arrastre de vapor de agua, a partir de hojas previamente desecadas. Se llevaron a cabo la identificación botánica y el análisis morfoanatómico de la especie vegetal en estudio con el propósito de comprobar su autenticidad, paso fundamental para el inicio de la investigación. La caracterización química del aceite esencial se realizó por cromatografía gaseosa acoplada a espectrometría de masas (GC-MS); la cual reveló que el aceite está constituido mayoritariamente por carvacrol en porcentajes de 19,2; 11,9 y 19,5% correspondientes a las 2, 4 y 6 horas de extracción, además de la variedad de otros compuestos en menor proporción, apareciendo algunos particulares en los diferentes periodos de extracción. Se determinaron además la densidad, el índice de refracción, el pH, la solubilidad y el espectro UV como parámetros adicionales de caracterización. El rendimiento del aceite esencial fue del 1,71% al final del proceso de extracción, expresado en base seca. Palabras Claves: Origanum syriacum, Aceite esencial, Carvacrol, destilación por arrastre de vapor de agua Extraction and physicochemical characterization of Origanum syriacum L. essential oil extracted at different times through steam distillation.This research studied the chemical composition of the essential oil of Origanum syriacum L. -a new variety introduced in Paraguay-extracted at 2, 4 and 6 hours of processing respectively, by the method of steam distillation from dried leaves. Botanical identification and morpho-anatomical analysis of the plant species under study were conducted in order to check its authenticity, an essential step in the initiation of the investigation. Gas chromatography mass spectrometry (GC-MS) revealed that the essential oil is mainly constituted by carvacrol in percentages of 19.2, 11.9 and 19.5% corresponding to the 2, 4 and 6 hours of extraction respectively; as well as a variety of other compounds in lower amounts, a few particular ones appearing in the different extraction periods. The density, refractive index, pH, solubility, and UV spectra were also determined as additional characterization parameters. The essential oil yield was 1.71% on a dry base.
