Abstract: Mentha x piperita L. is an aromatic and medicinal species belonging to the family Lamiaceae that is popularly known as peppermint. The aim of this study was to evaluate the effects of organic fertilizer sources on the biomass production, yield and chemical composition of peppermint (Mentha piperita L.) essential oil. The experiment was conducted using a completely randomized design (CRD) with a 2 x 5 factorial scheme, two sources of manure (cattle and poultry), five doses (0, 3, 6, 9 and 12 kg m-2) and four replicates. Different doses of cattle and poultry manure significantly affected plant biomass production and the responses of other variables, including leaf area, leaf weight ratio, leaf area ratio, root:shoot ratio, yield and chemical composition. Organic fertilizer doses of 9.0 kg m-2 cattle manure and 8.3 kg m-2 poultry manure to obtain the maximum total dry biomass. The highest yield of essential oil was obtained by applying 11.8 kg m-2 poultry manure. Differences in the chemical composition of the essential oil were observed for only three components (menthone, pulegone and menthyl acetate) without significant changes in the menthol content. Mentha x piperita L. é uma planta aromática e medicinal pertencente à família Lamiaceae, popularmente conhecida como hortel -pimenta. No trabalho, objetivou-se verificar o efeito das fontes de aduba o organica na produ o de biomassa, no rendimento e na composi o química do óleo essencial de hortel -pimenta (Mentha piperita L.). O experimento foi conduzido em DIC, em esquema fatorial 2 x 5, com duas fontes de esterco, bovino e avícola, e cinco doses (0, 3, 6, 9 e 12 kg m-2), com quatro repeti es cada.

Abstract: This study evaluated the effects of inoculation with the arbuscular mycorrhizal fungi Glomus mosseae, Glomus intraradices A4 and Glomus intraradices B1 and two phosphorus levels (10 and 40 mg kg-1) on root colonization, plant growth, nutrient uptake and essential oil content in Mentha piperita L. The experiment was carried out in a greenhouse, in 4x2 factorial arrangement, in completely randomized design. At sixty days after transplanting, the mycorrhizal plants had significantly higher fresh matter, dry matter and leaf area compared to non-mycorrhizal plants. The inoculation increased P, K and Ca levels in the shoot which were higher under 40 mg P kg-1 of soil. Plants grown with 40 mg P kg-1 soil increased the essential oil yield per plant by about 40-50% compared to those cultivated with 10 mg P kg-1, regardless of the mycorrhizal treatment. Among the studied fungal species, inoculation with G. intraradices A4 and a high level of P significantly increased plant growth and essential oil yield, compared to the other studied mycorrhizal fungal species. In conclusion, inoculation of arbuscular mycorrhizal fungi into peppermint plants is a feasible alternative to increase the essential oil production and reduce the use of fertilizers required to obtain economic production of peppermint under phosphorus-deficient soil condition. Este estudo avaliou os efeitos da inocula o de fungos micorrízicos arbusculares Glomus mosseae, Glomus intraradices A4 e Glomus intraradices B1 e duas doses de fósforo (10 e 40 mg kg-1) sobre a coloniza o radicular, crescimento, absor o de nutrientes e óleos essenciais em Mentha piperita L. O estudo foi conduzido em casa de vegeta o no delineamento inteiramente casualizado em esquema fatorial 4x2. Sessenta dias após o transplantio, as plantas micorrizadas apresentaram massa fresca, massa seca, e área foliar significativamente maior em compara o as n o-micorrizadas. A inocula o aumentou o teor de P, K e Ca na parte aérea sendo superiores em 40 mg P kg-1 de solo. As plantas cultivadas com 40 mg P kg-1 de solo aumentaram a produ o de óleo essencial por planta cerca de 40-50% em rela o às cultivadas com 10 mg de P kg-1, independentemente da micorriza o. Dentre as espécies fúngicas estudadas, a inocula o com G. Intraradices A4 e com um elevado nível de P, aumentou significativamente o crescimento e rendimento de óleos essenciais em compara o com outras espécies de fungos micorrízicos estudados. Em conclus o, a inocula o dos fungos micorrízicos arbusculares em plantas de hortel é uma alternativa viável para aumentar a produ

Abstract: peppermint is used for medical treatments of nausea, gastrointestinal cramps, flatulence, gallstones, jaundice, anxiety, sputum and expulsion of intestinal worms. in micropropagation, bap (6-benzylaminopurine) and kin (kinetin) have been the most widely used sources of cytokinins. the aim of this study was to evaluate the effect of plant growth regulators in multiplication of peppermint. explants consisting of nodal segments from seedlings already established in vitro with approximately 0,5 cm were inoculated on ms medium supplemented with different combinations of bap and kin and 30 g l-1 of sucrose. the concentrations of cytokinins used were 0,0; 1,0 and 2,0 mg l-1 of bap and 0,0; 0,5 and 1,0 mg l-1 of kin. the experiment was set up in a completely randomized design with nine treatments consisting of five bottles each, and each vial contained four explants. the use of 2,0 mg l-1 of bap promotes the in vitro multiplication of peppermint, but decreases the survival rate. cytokinins increase fresh and dry weight of explants and the absence of these regulators provides the elongation in this specie.

Abstract: colored shade nets have been used to manipulate the vegetative development, improving the utilization of solar radiation by ornamental plants. this work aimed to study the effect of 50% reduction of par on vegetative growth of plants of catharanthus roseus (l.) g. don, using blue and red nets, and black net, in comparison to plants growing under full sunlight (lack of shading). the plants were obtained from seeds and treated for 180 days. biomass increment and distribution, pigment content (chlorophylls and carotenoids) and foliar nitrogen were evaluated. the red net caused an increase of total dry mass and total leaf area of plants when compared to the blue net, black net and the full sunlight treatment, however, except in relation to the last treatment, the red net caused lower contents of foliar nitrogen and pigments. the higher root/stem and chlorophyll a/b ratios and the lower leaf area and leaf dry mass of plants growing under full sunlight in relation to shaded plants indicate a more prominent effect of the higher irradiance than the spectral alteration. shading alters significantly the dry matter distribution and the use of shade nets of different colors affects the content of photosynthetic pigments of this species.

Abstract: Folkloric medicinal application of Pimenta pseudocaryophyllus popularly known as “craveiro” as calming agent is a commonplace in Campos do Jord o, SP, Brazil. Pharmacological screening of ethanolic leaf extract of Pimenta pseudocaryophyllus (EEPp) and its active fraction (s) for possible anxiolytic like effect became necessary in order to confirm its therapeutic claims by the populace. Preliminary investigation with oral administration of EEPp (0.5, 1.0 and 2.0 g/kg) was devoid of any sign of neurotoxicity. In barbiturate induced – hypnosis, EEPp 1.0 g/kg potentiated the pentobarbital-induced sleep (32% reduction in sleep latency and 20% increase in sleep duration) while only dichloromethane and aqueous fractions increases sleep duration. Based on the parameters evaluated in both the open field and light dark box models, only dichloromethane fraction among others showed consistent anxiolytic like effect.
