The right bank of the Mayo River has permanent tax, within which lies the Black River, Romero and Tioyacu, rivers that were identified and prioritized for the present study, the same ones that have their own similar characteristics for successful application design statistic used. Eichhornia crassipes floating species studied "Water Hyacinth" presents submerged roots, no apparent stem, provided with a rhizome, very special, consequential, from which a rosette of leaves that have a significantly inflated spongy surface shaped balloon that opens forming a bladder filled with air, whereby the plant can remain on the water surface and high reproductive capacity in water bodies mainly lentic. For this evaluation was hypothesized that the species Eichhornia crassipes "Water Hyacinth" is distributed in Romero, Black and Tioyacu rivers. Its comparison field was oriented by goals such as determin...

The right margin of the river In May presents permanent tributaries, inside which one finds the Rio Negro, Rosemary and Tioyacu, rivers that there were identified and prioritized for the present study, the same ones that possess own and similar characteristics for a correct application of the statistical used design. Floating studied species Eichornia crassipes 11 Water hyacinth 11 , he presents plunged roots, lacks apparent stem, provided with a rhizome, very particular! y, emergent, of that there is opened a rosette of leaves that have a spongy surface notably inflated in the shape of globe that forms a bladder full of air, by means of which the vegetable can be kept on the aquatic surface and high reproductive capacity in water bodies lenticos principally. For. the present evaluation one raised as hypothesis that the species Eichornia crassipes "Water hyacinth 11 , it is distributed i...
