| "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,... |

| Este estudo avaliou as possíveis interações entre o magnésio e os micronutrientes manganês, zinco, cobre e ferro, pela determinação de seus teores nos diferentes órgãos do Phaseolus vulgaris L. cv "Carioca", nas 5 coletas, realizadas a cada 14 dias, a partir do 25o dia após a semeadura. As plantas foram cultivadas em solução nutritiva com nível completo (48,6 mg.L-1), baixos (2,4 e 24,3 mg.L-1) e elevados (72,9 e 97,2 mg.L-1) de Mg. O delineamento experimental foi inteiramente casualizado, em esquema fatorial. Com os níveis baixos de Mg, observou-se a diminuição do teor desse mineral nas raízes, caule e folhas e de Cu nas folhas e o aumento de Zn nas folhas e de Mn nas raízes. Com 97,2 mg.L-1 de Mg, observou-se o aumento desse elemento nas folhas,... |

| Information on improved fall panicum cultivars and agronomical pratices is scarce because of the relatively small importance of this crop in Brazil. The present study aimed to evaluate levels of nitrogen sidedressing on plant development and biochemical characteristics of two fall panicum cultivars. The experiment was set up under plastic tunnel conditions in Botucatu, São Paulo, Brazil, with plants growing inside asbestos-cement boxes. The experimental design was a randomized block setup and treatments consisted of six levels of nitrogen fertilization (0, 40, 80, 120, 160, and 200 mg L-1) applied at the onset of tillering on two fall panicum cultivars (AL Mogi and AL Tibagi). The application of increasing levels of nitrogen to fall panicum plants... |

| The influence of potassium on the development of Mentha piperita L. was evaluated in the plants grown in nutritive solution modified by variations in potassium, at 6.0, 3.0, and 1.5 mmol L-1, establishing differences between treatments and corresponding, respectively, to the concentration proposed in Hoagland and Arnon's no. 2 solution and reductions by 50% and 75%. Until 21 days after transplanting, the concentration used was diluted to 50% in the three treatments. Evaluations consisted of leaf area, development of the above-ground part, and dry matter of different plant organs. Plants grown with 1.5/3.0 mmol L-1 K showed greater development of the above-ground part. Other variables were not different among plants in the different treatments. |

| Development of Mentha piperita L . on biosolids amended soil with levels equivalent to 0, 28, 56 and 112 t ha-1 was evaluated. In order to measure the productivity and its relation with mint essential oil yield, different indices were determined: leaf area, total and several organ dry matter, leaf area ratio, specific leaf area, net assimilation rate and relative growth rate at 30, 44, 58, 72 and 86 days after planting (DAP), and essential oil yield at 90, 110 and 120 DAP. Physiological indices revealed that biosolids prolonged the vegetative phase of the plants, which adapted themselves to the presence of biosolids with time. Plants showed inverse behaviors in relation to productivity, resulting from the primary metabolism, represented by the shoot dry... |

| This research evaluated the effects of biosolid levels on yield and chemical composition of Mentha piperita L. essential oil. Mint plants were grown in a greenhouse in pots containing the equivalent to 0, 28, 56, and 112 t.ha-1 biosolid. Three evaluations were made at 90, 110, and 120 days after planting (DAP). The oil was extracted from the dry matter of shoots by hydrodistillation, and composition was determined by GC/MS. Oil production was slightly affected by the biosolid, increasing when plants were grown with 28 t.ha-1, a condition which did not result in quality improvement. Menthyl acetate was the component obtained at the highest percentage in all treatments. At 90 DAP, plants showed a higher percentage of menthol, the second-highest oil... |
