Efeito de doses de vermicomposto na produção de materia seca e óleo essencial de Foeniculum vulgare

Introdução:.O cultivo de plantas medicinais é uma prática essencial para a conservação das espécies e para garantir a oferta de matéria-prima com padrão de qualidade constante. Para que a terapia com plantas medicinais tenha eficácia e segurança, é imprescindível ao longo do cultivo, a execução de práticas fitotécnicas adequadas a cada espécie vegetal, visto que o desenvolvimento desta está sob a influencia das variações climáticas, dos cuidados com a irrigação, adubação, etc. Objetivo: Verificar os efeitos de diferentes doses de vermicomposto na produção de matéria seca e óleo essencial de Foeniculum vulgare Mill., cultivado em vasos em condições de estufa agrícola. Material e métodos: Sementes de F. vulgare foram colhidas no Horto de Plantas Medicinais e Tóxicas da FCF-UNESP e semeadas em vasos de 300 mL. Após 40 dias da semeadura as mudas foram transplantadas para vasos de 4L contendo solo tratado com vermicomposto nas doses de 0, 15, 30, 45 e 60 t ha-1. Ao final de 90 dias de cultivo as partes aéreas (folhas e caules) foram colhidas, secadas e analisadas quanto ao teor de óleo essencial. A identificação do anetol no óleo essencial foi realizada por CCD. Resultados: Os tratamentos durante o período de cultivo analisado influenciaram a produção de biomassa das plantas e também a produção do óleo essencial, porém sem uma correspondência diretamente proporcional. As plantas tenderam a produzir mais biomassa do que óleos essenciais em relação ao tratamento testemunha. Conclusão: Houve influência das doses de vermicomposto no cultivo de funcho (durante 90 dias, em vasos, em casa de vegetação), porém não correlacionada à produção de óleo essencial das folhas.

Relationship between race and clinical characteristics, extent of disease, and response to chemotherapy in patients with low-risk gestational trophoblastic neoplasia

Objective. To evaluate the potential effects of race on clinical characteristics, extent of disease, and response to chemotherapy in women with postmolar low-risk gestational trophoblastic neoplasia (GTN).Methods. This non-concurrent cohort study was undertaken including patients with FIGO-defined postmolar low-risk GTN treated with comparable doses and schedules of chemotherapy at the New England Trophoblastic Disease Center (NETDC) between 1973 and 2012. Racial groups investigated included whites, African American and Asians. Information on patient characteristics and response to chemotherapy (need for second line chemotherapy, reason for changing to an alternative chemotherapy, number of cycles/regimens, need for combination chemotherapy, and time to hCG remission) was obtained.Results. Of 316 women, 274 (86.7%) were white, 19 (6%) African American, and 23 (7.3%) Asian. African Americans were significantly younger than white and Asian women (p = 0.008). Disease presentation, and extent of disease, including antecedent molar histology, median time to persistence, median hCG level at persistence, rate of D&C at persistence, presence of metastatic disease, and FIGO stage and risk score were similar among races. Need for second line chemotherapy (p = 0.023), and median number of regimens (p = 0.035) were greater in Asian women than in other races.Conclusions. Low-risk GTN was more aggressive in Asian women, who were significantly more likely to need second line chemotherapy and a higher number of chemotherapy regimens to achieve complete remission than women of African American and Asian descent. Further studies involving racial differences related to clinical, biological and environmental characteristics are needed. (C) 2015 Published by Elsevier Inc.

Subdoses de glyphosate no desenvolvimento de espécies arbóreas nativas

Recovery of degraded areas aims to provide the degraded environment favorable conditions for restructuring in an environment that is unable to regenerate itself and planting of tree seedlings is one of the effective ways to extend this process. However, native tree species have slow growth rate which increases the seedlings production time as well as decreases their competitiveness with weeds in areas of forests deployment. The aim of this study was to evaluate the effects of glyphosate reduced rates application on Psidium cattleyanum (yellow guava), Citharexylum myrianthum (pau-viola) and Cedrela odorata (cedro) seedlings development by analyzing its morphophysiological parameters. The experiment was carried out in greenhouse conditions and the experimental units consisted of one plant were conducted in 2.5L plastic pots and arranged in a completely randomized design with six replications. Treatments consisted of glyphosate application at 0, 7.5, 15, 30 and 60 g ha(-1) using Scout (R) commercial formulation. Treatments application on these species seedlings was realized 120 days after seeds germination. Visual evaluations of plants phytotoxicity were realized at 7, 14 and 21 days after treatments application and plants survival, stomatal conductance, height, stem diameter and dry mass of shoots were evaluated 90 days after treatments application. Different doses of glyphosate did not cause plants phytotoxicity. Already, 30 and 60 g ha(-1) of glyphosate provided greater increases in height, stem diameter and dry mass of shoots for Citharexylum myrianthum and Psidium cattleyanum, respectively.

Desenvolvimento inicial de maracujazeiros (Passiflora edulis f. flavicarpa, P. edulis f. edulis e P. alata) enxertados sobre Passiflora cincinnata

The present work aimed to evaluate the initial growth and leaf mineral levels in passion fruit trees (Passiflora edulis f. flavicarpa Deg., P. edulis f. edulis Sims. and P. alata Dryander) grafted onto Passiflora cincinnata. To obtain seedlings, seeds were sown in plastic bags (500 mL) and hypocotyl grafting was performed when seedlings reached the stage of two fully expanded leaves. Fifteen days after grafting, plants were transplanted to 10L pots filled with previously limed and fertilized soil. Each pot contained two plants and corresponded to one plot. For each commercial species studied as rootstock, experimental design was completely randomized, in 3x5 (plant type x time of harvest) factorial arrangement, with four replicates of two plants per plot and five destructive harvests. Plant types were ungrafted P. cincinnata, ungrafted commercial passion fruit tree and commercial passion fruit tree grafted onto P. cincinnata. The first harvest was performed at 15 days after transplanting and the remaining ones at 14-day intervals (60, 74, 88, 102 and 116 DAS). At each harvest, the number of leaves per plant was counted, and leaf area, stem length, and stem, root, leaf and total dry matter were estimated. At the last harvest, the mineral composition (macro and micronutrients) of plants was analyzed. In general, it was observed that grafting onto P. cincinnata did not interfere negatively with the initial development and mineral levels of commercial passion fruit trees, and this interference varied according to the used canopy.
