A conservacao in vitro e uma das alternativas de que se dispoe para a manutencao do germoplasma da banana. Utilizando-se esta tecnica podemos manter numeroso genotipos (clones, variedades, especies silvestres) em espaco reduzido, sob condicoes controladas de luz e temperatura, protegidos de inimigos naturais (pragas e doencas), bem como de condicoes ambientais e climaticas adversas; beneficia tambem o intercambio de germoplasma porque o material mantido in vitro encontra-se em estado fitossanitario apropriado para ser enviado a outras regioes sem o risco de disseminacao de enfermidades. A conservacao in vitro compreende tres etapas basicas>o estabelecimento in vitro do apice caulinar; a multiplicacao da plantula inicial para obter o numero desejado de plantulas a serem conservadas e a conservacao propriamente dita, em meio de cultura que propicie o crescimento lento das plantulas. O sistema compreende: 1)Coleta do material no campo; 2)Preparacao do material; 3)Desinfestacao superficial dos cones; 4)Isolamento do apice caulinar; 5)Inoculacao e cultivo dos apices; 6)Micropropagacao dos brotos; 7)Enraizamento dos brotos e 8)Transferencia para novo meio de conservacao. Antes da remocao para novo meio, devera podar os apices foliares, eliminar as raizes velhas e regioes oxidadas e posteriormente, inocular em meio novo. |

The resurgent navigation project known as the Hidrovia Paraguay-Paran´a threatens the integrity of the Pantanal, the world’s largest wetland, which is considered a biome of its own. Intensive barge navigation is intended to transport crops (soybean, sugar, corn) and cement, iron and manganese from areas of production in Brazil, Paraguay and Bolivia to the oceanic ports of the Plata River. This short communication assembles the information available on the potential impacts of the planned deepening of the natural channel of the Paraguay River in its ~700 km-long upper section. These river channel alterations would disconnect the river from its floodplain, shorten the inundation period, and shrink the wetland area, resulting in severe degradation of the globally outstanding biological and cultural diversity of the Pantanal. The river sediments are mostly sandy and would require perpetual dredging. The reaches needing the most intensive dredging are those of the highest ecological value, protected as a National Park, UNESCO World Heritage and Biosphere Reserves, and various Indigenous reserves and Ramsar sites. Climate change is projected to increase the occurrence of low water periods. Between 2019 and 2021, navigation was impossible even in the already-deepened reaches of the Paraguay River between Corumb´a and Asuncion during long periods of the year. Thus, despite considerable financial and technical efforts, the success of the navigation project is doubtful, whereas enormous environmental, cultural, and social impacts can be anticipated. For these reasons, the Brazilian government had already turned down the project in 2000. We suggest alternative, less impactful modes of transport of commodities, e.g., via railway.
