“…According to Mainieri and Chimelo (1989), the cellular structures of these genera are similar. Nevertheless, Santini Junior (2013) and Soares et al (2014) reported the difference between these taxa, particularly in the stratification of wood rays, as Bowdichia sp. has this feature, while Diplotropis sp.…”

Anatomical characterisation of wood plays an important role in the recognition and confirmation of identity of commercially important timbers. Hence, the objective of the present study is to establish macroscopic identity of tropical wood species commercialised in Lavras, city of Minas Gerais/Brazil, and to verify whether the commercial names given to these species differentiate them from other wood species studied. Wood planks were obtained from commercial timber industries in Lavras region. The samples were passed through identification screening, anatomical characterisation, commercial nomenclatural analysis and visual comparison between the samples collected with available reference materials. According to the results, the trade nomenclature used for lumber industry was in agreement with the literature, except for the taxon Goupia glabra (Goupiaceae), and its common name Perobinha should be replaced by Cupiuba. Evaluation of several features affirmed that the axial parenchyma patterns, the vessel porosity and the presence of storied rays were essential to distinguish families, tribes and typical forest species of the Brazilian flora. Based on the results it was concluded that wood anatomy is an effective mechanism in the identification of commercial timbers, including endangered taxa such as Cedrela (Meliaceae).

“…Não conhecem o potencial de recuperação da floresta e do quantitativo do estoque de volume extraído que poderá ser recuperado pela mesma em um ciclo de corte, portanto, não realiza o manejo florestal. Esse fato está ligado principalmente à oferta abundante de madeira de diversas espécies na Amazônia (Soares et al, 2014).…”

O objetivo deste trabalho foi avaliar o comportamento das espécies através do índice de valor de importância, verificamos as mudanças ocorridas na diversidade de árvores comerciais ao longo do tempo. A variedade de espécies foi determinada pelo Índice de Valor de Importância (IVI) e depois classificada em grupos de uso. Sapotaceae foi a família mais abundante em todo o estudo apresentando o maior volume e área basal. Pouteria spp., Goupia glabra e Manilkara huberi podem ser selecionadas para uma nova colheita devido a recuperação na taxa de crescimento. Atualmente, podem ser utilizadas para uma segunda colheita florestal 16 espécies comerciais somadas a mais 52 novas espécies. Devendo haver estudos de novas espécies para compor a exploração florestal levando em consideração a quantidade de indivíduos remanescentes, sua distribuição na área e a dominância dessa espécie em relação aos outros indivíduos.

“…The interest in allelopathy has been growing exponentially in recent decades (ALVES et al, 2018;ALVES et al, 2021;VASCONCELOS et al, 2022), due to the discovery of natural herbicides that act directly on weeds and do not cause damage to the environment (TAIZ & ZEIGER, 2004). It can be defined as a process where the metabolic products of a certain species influence the metabolism of another species, either in the germination or in the growth of the nearby plant (SOARES, 2000).…”

Piperaceae is a family of basal angiosperms comprising about 3,615 species distributed in a pantropical form. In Brazil, there are about 458 species distributed in four genera, Piper L. and Peperomia Ruiz, and Pav. the most representative. Piper comprises shrubs and subshrubs. The best-known species of the genus is the black pepper (P. nigrum L.), a spice used for many years. Representatives of the genus are often used in folk medicine and the manufacture of medicines, as well as in the production of insecticides due to the properties of their essential oils. Among the most varied uses, oils can play an allelopathic or mutagenic role, and these are the objects of recent studies in several aromatic plants. Certain doses of these oils can inhibit or accelerate the growth of other vegetables. In addition, they can cause cellular changes that can lead to death. Based on this, this study aims to determine the concentrations of P. aduncum L. leaf extract that plays an allelopathic role and toxic gene cite in a model organism. The extract of P. aduncum was prepared from the leaves of 3 individuals, prepared at concentrations of 100 mg mL-1, 50 mg mL-1, 25 mg mL-1, and 12.5 mg mL-1. The design was completely randomized, with 5 treatments and 5 replications. Distilled water was used as a negative control. For allelopathy analysis, the following parameters were evaluated: germination speed index (GVI); germination percentage, root growth (CR), and aerial growth (AC). For the cytogenetic analysts, slides of the roots collected and fixed in ethyl alcohol: acetic acid by the crushing technique were prepared. The results show that the aqueous extract of P. aduncum leaves had an inhibitory effect on the germination and development of Lactuca sativa seeds, besides causing cellular changes such as bridges, C-metaphase, and chromosome loss.
