14. Germination, callus induction, micropropagation and foliar anatomy of candeia (Eremanthus erythropappus Mac Leish). / GerminaÃÃo, induÃÃo de calos, micropropagaÃÃo e anatomia foliar da candeia (Eremanthus erythropappus (DC.) Mac Leish)
Among medical arboreous species candeia (Eremanthus erythropappus Mac Leish) has many useful purposes. Nowadays its mainly product of interest is its oil extracted from the whole plant that and that contains alfa-bisabolol. This active principle is largely used in the pharmaceutical industry and cosmeceutica. The alfa-bisabolol purified has its market value

17. Prospection survey and harvest optimization aiming at the management sustainability of a submontane semideciduous seasonal forest / Inventário de prospecção e otimização da colheita visando a sustentabilidade do manejo de uma floresta estacional semidecidual submontana
Among the activities which form a forest management system, harvest is the most expensive one, and when it is carried out with no planning it causes severe damages to the forest structure. To perform a low impact exploitation, that is, to minimize damage to the natural regeneration, that is, to minimize damage to the natural regeneration and remaining trees,
