Key messagePhloeomyzus passeriniican induce a pseudogall within the bark of susceptible poplar genotypes, while in resistant genotypes the induction seems to be impeded by lignification processes. Abstract Phloeomyzus passerinii is a major pest of poplar stands in Europe, North Africa and the Near East. This aphid feeds in the cortical parenchyma of different poplar species and hybrids,...
Key message This study showed that Themachhi is genetically very close toC. medicaand consistently grouped with the typical citron in all the phylogenetic trees; hence revealed the identity of ‘Themachhi’ as a natural wild type ofC. medica. Abstract Taxonomic identity and well-supported phylogenetic relationships...
Key messageStem guying to prevent wind-induced swaying of radiata pine trees resulted in significant changes in radial growth, but did not affect the frequency of compression wood or resin features. Abstract Mechanical stress resulting from wind forces acting on trees can cause a number of direct and indirect effects ranging from microscopic changes in...
Key messageWe conducted molecular characterization of Nicaraguan Pinus tecunumanii populations using microsatellite markers. Populations possess considerable genetic variation but there are risks associated with inbreeding and population fragmentation. Abstract We carried out a molecular characterization of three natural populations of Pinus tecunumanii using nine microsatellite markers...
Key message Climate is the main driver of Aleppo pine radial growth variability irrespective of site productivity, with the climate effects on tree growth more limiting from 1970 onwards. Abstract Forest management adaptation to climate change requires identifying the previously most vulnerable stands and the possible climate impacts on forests. This study evaluates whether site index, as an...
