Melhoramento do sobreiro para uma regeneração artificial sustentável
Gaspar, Maria J.; Rodrigues, Ana P.; Faria, Carla; Silva, F. Costa e; Merouani, H.; Silva, J. Costa e; Correia, António H.; Rodrigues, J.C.; Graça, J.O sobreiro (Quercus suber) é uma espécie singular devido à sua importância no funcionamento do ecossistema mediterrânico e na produção de cortiça. No entanto, apesar da sua importância ecológica e sócio-económica, pouco se compreende ainda dos seus processos de adaptabilidade às diferentes condições ambientais. Em algumas áreas do mediterrâneo ocidental, as florestas de sobreiro encontram-se em declínio e a man...

Patrício, Maria do Sameiro; Nunes, Luís; Monteiro, Maria do Loreto; Almeida, HelenaQuercus suber (Cork oak), an important species in the areas of Mediterranean influence, presents high potential of expansion regarding expected climatic changes. Nowadays, cork oak area in Trás-os-Montes is 6380 hectares and is an important species to consider in the adaptive silviculture strategies in response to the climatic changes. Cork oak woodlands plays an important role on the rural economy, as a source...
Systemic immunity against soil borne Phytophthora and control of ink disease of...
Gouveia, Eugénia; Coelho, Valentim; Fonseca, Felícia; Nunes, Luís; Monteiro, Maria do LoretoChestnut ink disease represents a great risk for chestnut (Castanea sativa Mill.) in all regions of chestnut production of Europe and North America. Induced by soil borne oomycetes, Phytophthora cinnamomi and P. cambivora, both parasites infect the root system and cause root and collar rot resulting in dieback, decline and finally, the death of infected trees. There are no single control measures for root rot p...

Patrício, Maria do Sameiro; Pereira, Ermelinda; Claro, Ana Marília; Fernandes, Maria José; Nunes, Luís; Monteiro, Maria do LoretoSweet chestnut (Castanea sativa Mill.) is an important species in Northern Portugal as for fruit as well as for timber. Today, the role of the chestnut areas is not limited to production of fruit and timber but also to other aspects such as landscape, environmental and ecological protection, which are very important. Consequently, its sustainable management is essential in maintaining the health and vitality of...
Potential of local hypovirulent strains of Cryphonectria parasitica for biologi...
Gouveia, Eugénia; Coelho, Valentim; Monteiro, Maria do LoretoCryphonectria parasitica, introduced in the NE of Portugal since 1989, is now an important and widespread pathogen of chestnut (Castanea sativa Mill.) which causes losses in chestnut fruit production and led to decline and death of many chestnut trees. Hypovirulence, a virus mediated attenuation of fungal pathogenesis, has not been frequent until now in Portugal but recently some cases of healing cankers were r...
