Ecological risk assessment of Piper aduncum essential oil in non-target organisms
MIURA,Patrícia Tidori; JONSSON,Claudio Martín; QUEIROZ,Sonia Claudia do Nascimento de; CHAGAS,Edsandra Campos; CHAVES,Francisco Célio MaiaABSTRACT One possible alternative to chemotherapeutic agents in the treatment and prevention of diseases in fish farms is the use of Piper aduncum essential oil. However, ecotoxicological data are required to ensure its proper use and to prevent adverse effects on non-target organisms. These data are relevant since this essential oil is described as having insecticidal, molluscicidal and cytotoxic activitiy tha...
Seeds of sacha inchi (Plukenetia volubilis, Euphorbiaceae) as a feed ingredient...
ARAÚJO-DAIRIKI,Thyssia Bomfim; CHAVES,Francisco Célio Maia; DAIRIKI,Jony KojiABSTRACT Sacha inchi (Plukenetia volubilis) is a plant native to the Peruvian Amazon with seeds that contain 24 to 29% protein, and levels of vitamin A and E and omega 3 polyunsaturated fatty acids that are suitable for fish nutrition. Thus, this study aimed to evaluate the use of sacha inchi seeds as an ingredient in the diets of tambaqui (Colossoma macropomum) and matrinxã (Brycon amazonicus). The acceptance ...
Genetic diversity among accessions of sacha inchi (Plukenetia volubilis) by phe...
RODRIGUES,Haroldo Silva; BORÉM,Aluízio; VALENTE,Mágno Sávio Ferreira; LOPES,Maria Teresa Gomes; CRUZ,Cosme Damião; CHAVES,Francisco Célio MaiaABSTRACT Sacha inchi (Plukenetia volubilis) is native to the Amazon region and has a high seed content of mono and polyunsaturated fatty acids, making it interesting for the pharmaceutical and cosmetic industry. The purpose of this study was to analyze sacha inchi genetic diversity and describe accessions based on phenotypic characteristics. Fruits and seeds of 25 accessions from the sacha inchi genebank of Emb...
Repeatability of biometric and fruit and seed yield traits of sacha inchi
VALENTE,Mágno Sávio Ferreira; LOPES,Maria Teresa Gomes; CHAVES,Francisco Célio Maia; OLIVEIRA,Ariane Mendes; FREITAS,Diego Rodrigo Bilby deABSTRACT Repeatability allows an estimation of the number of evaluations needed to optimize the selection of superior genotypes, with consequent effects on the research costs in terms of financial and human resources. The objective of this study was to estimate the coefficient of repeatability of biometric and yield traits, related to fruits and seeds of sacha inchi (Plukenetia volubilis), and to define the num...
Ethnobotanical study of antimalarial plants in the middle region of the Negro R...
TOMCHINSKY,Bernardo; MING,Lin Chau; KINUPP,Valdely Ferreira; HIDALGO,Ari de Freitas; CHAVES,Francisco Célio MaiaABSTRACT The middle Rio Negro region is an interesting place to seek novel antimalarial compounds because of the traditional knowledge of the Amazon population in conjunction with the high biodiversity of the region. The objective of this work was to study the use of antimalarial plants in Barcelos, state of Amazonas, Brazil. Fifty-two local specialists from eight different communities were interviewed over one...
