| Spiked pepper presents a high yield of essential oil with useful biological properties for human health and agriculture. In order to evaluate the morphoagronomic variability and, afterwards, to select genotypes for plant breeding and cultivation, thirteen clones were propagated. Thus, spiked pepper cuttings were rooted under greenhouse, transferred to a nursery and, afterwards, planted at the experimental area. The evaluations were carried out in two harvest seasons. The evaluated morphoagronomic traits were number of leaves per branch, leaf length, leaf width, diameter of the oldest branch, plant height, number of orthotropic branches, number of plagiotropic branches, internode length, fresh and dry matter, yield of essential oil and dillapiole content.... |

| Spiked pepper (Piper aduncum L.) is an aromatic plant species with high essential oil production. It is a species that occurs abundantly in the Brazilian Amazon. Its essential oil has exploitable biological properties in the human health and agriculture. Aiming to study its germplasm toward future use in genetic breeding programs, collecting was carried out (inflorescences, cuttings, leaves and thin branches) in ten provenances from the Brazilian Amazon. Twelve morphoagronomic traits were determined to take the data: number of leaves by branch, length of leaf, width of the leaf, circumference of the older branch, height of the plant, number of orthotropic branches, number of plageotropic branches, length of the internodes, number of spikes per branches,... |
