O resgate e a manutenção dos conhecimentos tradicionais associados ao uso de plantas medicinais são essenciais às comunidades tradicionais, como os povos quilombolas, especialmente porque esses recursos são de fácil acesso, sendo, muitas vezes, o principal meio de cuidado com a saúde. Dessa forma, objetivou-se realizar o levantamento das plantas medicinais utilizadas por mulheres em comunidades quilombolas do Recôncavo Baiano. O trabalho foi desenvolvido em quatro comunidades: Engenho da Cruz, Mutecho Acutinga, Terreno do Governo e Guaruçu, nos municípios de Cachoeira, São Félix e Maragogipe, no Recôncavo Baiano. Os dados foram coletados a partir de uma amostragem intencional não probabilística com entrevistas semi-estruturado a 25 mulheres quilombolas que fazem parte de Empreendimentos de Economia Solidária nas suas respectivas comunidades. Quarenta espécies de plantas foram citadas como recurso medicinal. Lippia alba (erva-cidreira, Verbenaceae) foi a espécie mais citada (n = 22), estando presente em 22 quintais. As folhas se destacaram como a estrutura vegetal mais utilizada para o uso via oral na forma de chá. Entre as participantes da pesquisa, as plantas medicinais oferecem oportunidade de cuidado com a saúde, achados que sugerem sua importância biocultural.
Soil temperature is a physical property of great agricultural importance in the soil-plant relationship and in energy exchange with the atmosphere. This study was conducted in a degraded Cambissolo Háplico Ta Eutrófico (Cambisol; Inceptisol) in the Irecê Identity Territory, Bahia, Brazil, aiming to evaluate the hourly, daily, and monthly fluctuations of soil temperature at depth, and soil thermal diffusivity in the castor bean crop. Hourly soil temperature data from February 4, 2014, to September 30, 2015, were obtained by using thermocouple sensors (copper-constantan) horizontally installed at 0.05, 0.10, and 0.20 m depths. Soil thermal diffusivity was estimated by phase and amplitude methods. Results showed that, for most days, the soil temperature was at the level recommended for castor bean. The maximum and minimum hourly and daily soil temperatures were observed in October and July, respectively, and the maximum soil temperature values occurred at 4 p. . Soil temperature variability is low, requiring few measurement points to estimate this factor in an area. The amplitude method led to soil thermal diffusivity values compatible with results in the literature. The absence of a relationship between thermal diffusivity and soil moisture was attributed to the clay-loam soil texture, predominance of micropores, and iron oxides allowing greater approximation to the soil particles, with high thermal diffusivity even under low soil moisture conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
