Levantamento Fitossociológico De Plantas Daninhas Em Pomares De Mangueira No Semiárido Mineiro

Abstract: Objetivou-se identificar as principais espécies de plantas daninhas em cultivo de mangueira aos dois e oito anos após plantio. O estudo foi desenvolvido em áreas irrigados de manga ‘Palmer’ localizadas em Janaúba-MG. Para estudo fitossociológico das plantas daninhas foi utilizado o método quadrado inventário (0,25 m2). Após classificação e quantificação das espécies, foi calculado calcularam-se a frequência (F), frequência relativa (Fr), densidade (D), densidade relativa (Dr), abundância (A), abundância relati… Show more

“…The poaceae family still stands out in crops of several other crops, both annual and perennial, being observed in bean varieties (Silva et al, 2017), cassava (Cardoso et al, 2013;Soares et al, 2015), sugar cane (Soares et al, 2011) papaya (Costa et al, 2019), pineapple (Sarmento et al, 2017), orange (Santos et al, 2015) and mango (Sena et al, 2019). This wide distribution of weeds from the poacea family is directly related to the large amount of seeds produced, which provides an increase in the dissemination power of these species (Maciel et al, 2010).…”

“…The following phytosociological variables of burnable herbaceous plants were analyzed: frequency (F); relative frequency (Fr); density (D), which enables to determine the quantity of plants of each species per unit of area; relative density (Dr); abundance (A); relative abundance (Air); importance index (IVI) (Mueller-Dombois;Ellenberg, 1974) and relative importance index (IVIr) (Braun-Blanquet, 1979). The variables Fr, Dr, and Air shows information on the relation between the species found in the area, and are used to obtain the IVI (Sena et al, 2019).…”

“…Semelhante aos resultados encontrados por Sena et al (2019), em levantamento de plantas daninhas em pomares de mangueiras, a espécie Sida rhombifolia apresentou maior valor de IVIr (Tabela 5). Este índice representa quais espécies ou grupos de espécies devem ter maior prioridade na ordem de controle.…”
