The goal of the present study was to characterize anatomical and biochemical changes in rice plant roots in response to seed treatment with rhizobacteria (Burkholderia pyrrocinia (R-46) + Pseudomonas fluorescens (R-55)) and Trichoderma asperellum (Ta: mixture of strains T-06, T-09, T-12, and T-52).The experimental design was completely randomized, with six treatments (R-46, R-55, R-46 + R-55, Ta+ R-46 + R-55, Ta, and control) and ten replicates. Treatments Ta and R-46 + R-55 increased the root length and diameter as well as the cortex expansion and induced a 2% expansion of the aerenchymal space. Treatments Ta and R-46 increased the vascular cylinder diameter. The number of protoxylem poles and metaxylem vessel elements was increased by R-46 and R-55. The total phenol content increased with treatments Ta, R-46 + R-55, R-46, and R-55, and all the treatments increased the flavonoid content. The lignin content increased with the Ta and R-55 treatments. All the root architecture modifications resulting from the interaction between seedlings and bioagents (rhizobacteria and Trichoderma spp.) observed in the present study favored the root plasticity of rice seedlings. |

Thirty sites along the Rio Negro and Rio Taboco were sampled. The Upper Rio Negro region has a typical 20 meter strip of evergreen gallery forest (mata ciliar) growing along the river, while plants more closely associated with cloud forests grow around permanent waterfalls. The distribution and conservation status of these plants - including Begoniaceae, Gesneriaceae, Centropogon (Campanulaceae), Peperomia (Piperaceae), Pitcairnea (Bromeliaceae), and numerous ferns and mosses - should be studied. Althouth the active rivers harbor very little aquatic vegetation, in the backwaters the aquatic plant species proliferate into huge mats dominated by any of a dozen different emergent species, and (in the deeper water) by the floating plant species. The backwaters of the floodplain of the Middle Rio Negro (excluding the vazantes and baias) with high-density stands of aquatic plants, are also of special importance as breeding grounds for the fishes and macrocrustaceans. With respect to woody plants, the Cambara - probably the most important timber species of the Pantanal, which also has medicinal properties - can be seen in abundance colonizing the flooded savanna terraces. However, its regeneration on the floodplain is very spotty. Most of the large Cambara individuals on the floodplain (based on several hundred trees checked) seem to be recently dead or very unhealthy, with many dead small branches. This is probably caused by a natural die-off which may be hastened by a large quantity of guano left by birds using the dead branches as roosts. The formation of cordilheiras, baias and salinas seems to be unique to the Nhecolandia region of the southern Pantanal, between the Rio Negro and the Rio Taquari to the north. No other area of the Pantanal - or of the world - has such topographic or ecological systems. The baias harbor great concentrations of aquatic plants, and are remarkable in the radical difference in aquatic vegetation from one baia to the next. Physical and chemical factors clearly play a role, as evidenced by the dominance of Paspalum vaginatum, a plant of ocean beaches, on the sandy shores of the salinas. Aquatic plants were rare in the upper sites sampled, except for the few amphibious species on the tiny beaches, but they were common in the lowest sites, on narrow, backwater arms of the river, which were covered with floating mats (but no emergents). In contrast, both sites sampled on the Rio Negrinho - a backwater flooded pasture and a swamp - had extensive mats of floating and emergent aquatic plants.
