Genetic diversity of “Pimenta Longa” genotypes (Piper spp., Piperaceae) of the Embrapa Acre germplasm collection
The commonly known Pimenta longa is a commercially valuable natural resource found wild in Acre, Brazil. Specifically, three Piperaceae species with contested taxonomic status were studied, Piper hispidinervum, Piper aduncum, and Piper hispidum, to assesses the interand intra-specific genetic relationship of 49 Piper genotypes kept in the Pimenta longa germplasm collection at Embrapa Acre, usin...
متن کاملPiper aduncum against Haemonchus contortus isolates: cross resistance and the research of natural bioactive compounds Piper aduncum contra isolados de Haemonchus contortus: resistência cruzada e a pesquisa de bioativos naturais
The anthelminthic activity of the essential oil (EO) of Piper aduncum L. was tested in vitro on eggs and larvae of resistant (Embrapa2010) and susceptible (McMaster) isolates of Haemonchus contortus. The EO was obtained by steam distillation and its components identified by chromatography. EO concentrations of 12.5 to 0.02 mg/mL were used in the egg hatch test (EHT) and concentrations of 3.12 t...
متن کاملColheita, beneficiamento e controle de qualidade de sementes de nabo forrageiro
The oil radish siliques maturation occurs in a non-uniform way, which makes it difficult to define the ideal harvesting time in order to produce high quality seeds. In addition, the high lipid content of the seed may hamper its preservation. To evaluate the effect of the maturation stage at harvesting on the physiological quality and chemical composition of the oil radish seeds stored under dif...

متن کاملEfeito da Densidade de Plantas e Posição das Sementes na Planta-Mãe sobre as Características Fisiológicas de Sementes de Carrapicho (Xanthium strumarium)
Experiments were conducted in 2010 to determine the influence of plant density and seed position on the mother plant on seed physiological characteristics of cocklebur (Xanthium strumarium). Cocklebur burs were collected in fall of 2010 from Research Farm of University of Agricultural Sciences and Natural Resources of Gorgan, Iran. The experiment was established as factorial arrangement using a...
