“…Onion cultivation is of great socioeconomic importance in the country, since it is cultivated by small producers and demands a large amount of labor, generating employment and income and maintaining producers in the rural area (Resende and Costa, 2009;Lima et al, 2011a). In addition to being an extremely versatile plant and having good acceptance due to its spicy flavor, nutritional and medicinal value (Kale and Ajjappalavara, 2015).…”

The Southwest region of Pará state, Brazil, imports 100% of all onion consumed from other regions of the country, which generates market dependence and raises the product's costs. The present study investigated parameters related to germination, agronomic performance and postharvest characteristics of five onion cultivars at different planting densities. The experiment was conducted in two stages. In the first, in a greenhouse, the germination kinetics was evaluated. In the second, in the field, the seedlings were transplanted into beds. The experimental design was in complete randomized blocks in a 5 x 3 factorial scheme with three replications. The treatments consisted of the combination of five cultivars (Mata Hari, Dulciana, Cimarron, NUN 1205-F1 and Vale Ouro IPA 11) and three line spacing (20, 30 and 40 cm) 8 cm between plants. As for the germination rate (GR), the results allowed to highlight the cvs. Cimarron and Vale Ouro IPA 11 with an 80.55% and 77.77% of GR, respectively. There was a significant difference for total bulb productivity, highlighting Vale Ouro IPA 11 in the 8 x 20 cm spacing. For the bulb diameter, cv. Vale Ouro IPA 11 obtained the best results in all classes. In the average weight of the bulbs, cv. Vale Ouro IPA 11 in the 8 x 40 cm spacing was the best treatment with 60.77g. As for total soluble solids, cv. Vale Ouro IPA 11 presented °Brix higher than the others, being significant at 1%. These results demonstrate that it is possible to produce quality onions in the Southwest region of Pará, which would reduce prices, since all commercialized onions come from regions outside the state.

“…Quercetin is a flavonoid found in red onion (Allium ceppa L.) that has antioxidant, anti-inflammatory and anticancer functions. It is also possible to find such a compound in foods such as capers, yellow peppers, lemon, peeled apples, red grapes, broccoli, canned beers, among others foods, presenting a variable amount in each food 1 .…”

Background: Quercetin is a flavonoid widely found in plant kingdom and target of studies in pharmacological area due to its potent antinociceptive effect compared to analgesics used in conventional therapies. The aim was to evaluate its antinociceptive activity and antinociception mechanism. Methods: For this, 40 Norvegicus Wistar rats were used, divided into 4 groups: Q50 (treated with quercetin 50 mg/Kg), Q100 (treated with quercetin 100 mg/Kg), Q500 (treated with quercetin 500 mg/Kg) and Positive control (PC) without quercetin treatment), who were submitted through the pain induction methods by tail immersion and formalin in the first step to assess antinociceptive action and in the second step, tail immersion method receiving antagonists from opioid, cholinergic and nitric oxide - L-arginine to evaluate the action mechanism. Results: Quercetin antinociceptive activity was verified at the dose of 50 mg/kg and 100 mg/kg in tail immersion test after formalin injection, with better performance at the dose of 50 mg/kg. There were no statistically significant results in paw opening and capsaicin tests. Quercetin demonstrated a possible influence on opioid and cholinergic pathway, which was not observed on the nitric acid - L-arginine pathway in view of parameters tested. Conclusion: Quercetin performed the best antinociceptive activity at a dose 50 mg/kg and there was a possible influence on opioid and cholinergic pathways.

“…a cultura da cebola normalmente responde à adição de fertilizantes nitrogenados (Hassan, 1984;buwalda & Freeman, 1987;Greenwood et al, 1992). a dose de n que proporciona a máxima produtividade depende da cultivar (may et al, 2007) e de vários atributos do solo, principalmente dos teores de argila e de matéria orgânica (magalhães, 1988; vidigal, 2000), além das condições de cultivo (batal et al, 1994), e normalmente situa-se entre 100 e 200 kg ha -1 (magalhães, 1988;vidigal, 2000;may, 2006;Resende & Costa, 2009). entretanto, batal et al (1994 afirmam que alguns estudos têm indicado não haver incremento no rendimento de cebola pela adição de n, mesmo em solos de textura arenosa.…”
