Pinus pinea stands in Castile y Leon

Climate change is affecting the health and productivity of the Mediterranean stone pine (Pinus pinea) stands in the Spanish Northern Plateau. The main research lines for adapting this forest ecosystrems and mitigating the effect of climate change are presented. The finding should lead to recommendations for the future management of these stands.

Regulation of chestnut blight by hypovirulent strains

Symptoms of chestnut blight caused by: (1) non-virus-infected strains of Cryphonectria parasitica. (2) by virus-infected strains of Cryphonectria parasitica "hypovirulent" strains

A method is resented to reduce the severity of cankers caused by chestnut blight,  Cryphonectria parasitica. This pathogenic fungus penetrates and necroses cortical tissues, which provoke mortality of adult trees aerial parts and failure of grafting.

In the 1970s, French researchers developed a biological control method using hypovirulent strains of the fungus. Since then, a research programme at INRA conducted with several organisations (Chambers of Agriculture, Union of Chestnut production Associations, the Forest Health Department) aims at clarifying and improving...
