Phytosociology of spontaneous plants under agroecological cultivation in the banana tree in backlands of Paraiba
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 1
Abstract
Plants are sessile organisms and therefore reflect local conditions. They generally have higher levels of phenotypic plasticity compared to animals, which means that the effects of various stressors may be more apparent and potentially easier to measure and quantify. This work aimed to perform a phytosociological survey of the species of spontaneous plants present in the cultivation of different banana genotypes under agroecological management in Hinterland Paraibano. It was carried out in an experimental area of 1,512m2. The spacing between plants was 3x3 m. For the identification and quantification of spontaneous plants, the square inventory method was used. Frequency, relative frequency, density, relative density, abundance, relative abundance and relative importance index were calculated. A total of 93 individuals corresponding to 21 species were identified, distributed in 11 families. The area under study presented a great diversity of spontaneous plants in banana cultivation, being the most frequent (18.18%) and with greater relative density (38.70%) the species Cyperus rotundus, followed by Alternanthera tenella with relative frequency of 13.63% and relative density of 15.05%.
