Popis:	This study aimed to evaluate the litter production of different genotypes of Eucalyptus. An experiment was conducted in 43-month-old stands in the municipality of São Gabriel, Rio Grande do Sul, Brazil. For each genotype, a plot of 599.200 m was set. Fifteen samples were collected at random in each plot. The accumulated litter production ranged from 2.03 to 4.70 Mg ha-1. This number is the lowest value found in the Eucalyptus dunnii stands and the highest value in the hybrid Eucalyptus urograndis stands. The leaf fraction reached, on average, between 60% and 91% of the total litter. The various genotypes had differences in the litter deposited onto the soil top.
