Está e uma versão preliminar de trabalho cujo objetivo principal e identificar e analisar de que maneira o Sistema Agro-Indústrial do Café utiliza, ou se propõe a utilizar, a informática. Visando gerar subsidios a definição de procedimentos e politicas direcionadas ao seguimento do café, além de examinar possiveis impactos sociais e econômicos que a utilização de uma nova tecnológia possa gerar. O "estudo preliminar" alcança um total de dez cooperativas de cafeicultores, situadas na Região Sul de Minas gerais, e sintetiza o que existe no estoque de mudanças, conhecimentos, equipamentos e software. |

Abstract Yerba mate (Ilex paraguariensis) leaves have many compounds with proven bioactive activity; so, interest and consumption of species’ products have increased globally. Here, we used 19 yerba mate genotypes from a provenance and progeny trial, yielding findings that could have significant implications for the species’ vegetative propagation and genotype selection, where we indicate some potential genotypes, contributing to yerba mate silviculture and breeding programmes. We evaluated season and genotype effects on rooting of cuttings, con- tents of bioactive compounds and the influence of these compounds on rhizogenic process. We prepared semi-woody cuttings in four seasons; after 100 days we evaluated rooting vari- ables. Methylxanthines (caffeine and theobromine) and monocaffeoylquinic acids contents were measured using high performance liquid chromatography, from aqueous extract of stock plant mature leaves. There was no correlation between rooting variables and evaluated compounds. Just eight genotypes presented above 70% of rooted cuttings in at least one sea- son. Rooting variables varied between these genotypes and seasons. Caffeine and 5-caffeoyl- quinic acid (CQA5) significantly contributed to separated genotypes and seasons. CQA5 showed highest levels in spring. Regarding to genotypes, EC22 showed low levels of caffeine in all seasons. The great variation in compounds among genotypes indicates the possibility of breeding for chemical characteristics and raw material production for different products. Our results also indicate the importance of seasons for yerba mate vegetative propagation success and leaf compound contents.
