Resumo
The aim of this research was to evaluate the efficiency of phosphorus absorvation in twelve corn genotypes. The study was performed in presence and absence of arbuscular mycorrhizal fungus inoculation. The experiment took place at the Agrarian and Biological Center greenhouse, in the Federal University of Goiás, Jataí, Brazil. The genotypes were randomly distributed in blocks with three replicates in a 12x2x2 factorial. The genotypes were AG9010, P30K75, AG8060, P30P70, AG405, P30F33, AG7000, BANDEIRANTES, EMGOPA501, BALU178, DINA657, 2C599, cultivated under two doses of phosphorus (10 and 100mg kg-1 of P in soil solution) in presence or absence of Glomus etunicatum mycorrization. The study verified the difference among genotypes in dry root matter production. The ratio among root dry and shoot dry matter colonized with mycorrizal fungus was observed. Ratio accumulated phosphorus among shoot and dry root matter was also seen. The mycorrization changed classification of genotypes regarding to dry matter shoot production under low P and the response for higher P supply.
