Estudou-se o efeito de 4 concentracoes do acido naftalenoacetico, aplicadas em tres epocas distintas (Pre-florescimento, pleno florescimento e frutificacao) na descompactacao do cacho de uva cultivar 'Italia' (Pirovano 65). O delineamento estatistico foi o de blocos ao acaso com arranjo fatorial em tres repeticoes. As solucoes do acido naftalenoacetico (ANA) foram pulverizadas de maneira que atingissem todas as inflorescencias, cachos e vegetacao das plantas. O ANA causou descompactacao do cacho de uva quando aplicados nas tres epocas pre-estabelecidas. A concentracao a 5ppm quando aplicada durante as epocas de pre-florescimento e pleno florescimento mostrou-se superior as demais quanto a descompactacao, maior volume dos bagos e melhor aspecto dos cachos. As concentracoes a 10 e 20ppm causaram fitotoxidade e raleio excessivo durante as epocas de pre-florescimento e plena floracao. Os tratamentos 5, 10 e 20ppm foram eficientes na descompactacao dos cachos durante a epoca de frutificacao. No entanto, tal descompactacao nao proporcionou aumento no volume dos bagos remanescentes. A analise de variancia nao mostrou diferenca significativa ao nivel de 5% para a variavel oBrix, porem os dados obtidos permitem afirmar que o oBrix tendeu a aumentar nos tratamentos sujeitos a acao do ANA. |

Soils are self-organized ecological systems within which organisms interact within a nested suite of discrete scales. Microorganisms form communities and physical structures at the smallest scale (microns), followed by the community of their predators organized in microfoodwebs (tens of microns), the functional domains built by ecosystem engineers (centimeters to meters), ecosystems, and landscapes. Ecosystemengineers, principally plant roots, earthworms, termites, and ants, play key roles in creating habitats for other organisms and controlling their activities through physical and biochemical processes. The biogenic, organic, and organomineral structures that they produce accumulate in the soil space to form threedimensional mosaics of functional domains, inhabited by specific communities of smaller organisms (microfauna and mesofauna, microorganisms) that drive soil processes through specific pathways. Ecosystem engineers also produce signaling and energy-rich molecules that act as ecological mediators of biological engineering processes. Energy-rich ecological mediators may selectively activate microbial populations and trigger priming effects, resulting in the degradation, synthesis, and sequestration of specific organic substrates. Signalingmolecules informsoil organisms of their producers? respective presences and change physiologies by modifying gene expression and through eliciting hormonal responses. Protection of plants against pests and diseases is largely achieved via these processes. At the highest scales, the delivery of ecosystem services emerges through the functioning of self-organized systems nested within each other. The integrity of the different subsystems at each scale and the quality of their interconnections are a precondition for an optimum and sustainable delivery of ecosystem services. Lastly, we present seven general research questions whose resolution will provide a firmer base for the proposed conceptual framework while offering new insights for sustainable use of the soil resource.
