  <abstract>Abstract – The objective of this work was to evaluate the effect of the use of plastic mulch and percolation barrier on the growth and distribution of pineapple roots. The BRS Imperial cultivar was cultivated using plastic as mulching material and a percolation barrier. The evaluated variables were: relative and absolute root growth rates, root length distribution, and root length density. The use of plastic mulch resulted in a greater accumulation of root dry matter, with or without the percolation barrier. Under drip irrigation, mulching promoted a greater root development. The highest root growth rate occurred from 360 to 450 days after planting. The amount of roots was from 64.1 to 66.7% on the stem, and from 34 to 36% distributed in the 0.10 and 0.20 m soil layer. Black plastic, as mulch or a percolation barrier, contributes to increase the root development of 'BRS Imperial' pineapple under drip irrigation. Index terms: Ananas comosus, mulching, soil cover, water use efficiency.</abstract>
  <abstract>Resumo – O objetivo deste trabalho foi avaliar o efeito do uso de cobertura plástica e barreira de percolação no crescimento e na distribuição de raízes de abacaxizeiro. A cultivar BRS Imperial de abacaxizeiro foi cultivada com uso de plástico como cobertura do solo e como impedimento à percolação. As variáveis avaliadas foram: taxas de crescimento radicular relativo e absoluto, distribuição do comprimento das raízes e densidade do comprimento radicular. O uso do plástico como cobertura do solo resultou em maior acúmulo de matéria seca das raízes, com ou sem impedimento de percolação. Sob irrigação por gotejamento, o uso do plástico como cobertura do solo promoveu maior desenvolvimento das raizes. A maior taxa de crescimento radicular ocorreu dos 360 aos 450 dias após o plantio. A quantidade de raízes
foi de 64,1 a 66,7% no caule, e de 34 a 36% distribuídas na camada de 0,10 a 0,20 m do solo. O plástico preto, tanto como cobertura do solo quanto como impedimento de percolação, contribui para aumentar o desenvolvimento radicular do abacaxizeiro 'BRS Imperial' sob irrigação por gotejamento. Termos para indexação: Ananas comosus, mulching, cobertura do solo, eficiência do uso da água. </abstract>
