English abstract The effect of different population densities of Pratylenchus brachyurus on the growth of cotton (Gossypium hirsutum) plants was studied in three greenhouse experiments, using cultivars IAC 20 and IAC 22. Both cultivars proved to be good hosts to the nematode, which however did not affect plant height and affected only slightly fresh root weight and dry top weight of both cultivars, even at the highest population density (over 9,000 nematodes/plant)
Portuguese abstract O efeito de diferentes densidades populacionais de Pratylenchus brachyurus no crescimento de algodoeiro (Gossypium hirsutum) foi estudado utilizando as cultivares IAC 20 e IAC 22, em três experimentos realizados em casa de vegetação. Ambas as cultivares se mostraram boas hospedeiras de P. brachyurus, embora não afetando a altura das plantas e afetando apenas ligeiramente a massa fresca das raízes e a massa seca da parte aérea, mesmo sob a densidade populacional mais alta (acima de 9.000 nematóides/planta)
