The Douglas-Þr beetle, Dendroctonus pseudotsugae Hopkins, was detected in 2001 in northernMinnesota outside its natural range and the range of its native hosts, Douglas-Þr, Pseudotsuga menziesii (Mirbel) Franco, and western larch, Larix occidentalisNutt. Consecutive years of detection indicated that D. pseudotsugae may have been established in a new environment and provided a possible example o...

The aim of this study was to examine the symbiosis relationshipbetween some arbuscular mycorrhizal fungi (AMF) and Salsola laricina (Chenopodiaceae), a non-mycotrophic plant speciesand its effect on improving plant growth parameters. Initially, the development of AMF density was monitored through two parameters including evaluation of mycorrhizal colonization of plant roots and density measurem...

Exposure of wheat (Triticum durum L.) to NaCl (100 and 200 mM) showed that this variety is moderately halo tolerant. Germination rates in the absence and presence of salt (100 and 200 mM) are respectively 98.3, 83.3 and 53.3%. The supply of Salsola vermiculata and the combination between this halophyte and Streptomyces sp. SF5 affected germination significantly. Germination rates in the absence...

BACKGROUND Sensitivity to Salsola kali is a frequent cause of allergic respiratory disease in various regions of Spain. However, there are very few articles in which this allergen has been studied. METHODS AND RESULTS In order to evaluate the tolerance of this extract, a prospective study has been performed. This study was observational, multi-centred and open, involving 88 patients with alle...

The Amaranthaceae family is composed of about 180 genera and 2500 species. These common weeds have become increasingly relevant as triggers of allergy in the last few years, as they are able to rapidly colonize salty and arid soils in extensive desert areas. The genera Chenopodium, Salsola, and Amaranthus are the major sources of pollinosis from the Amaranthaceae family in southern Europe, west...

Chenopodiacea/Amaranthacea pollen is an important cause of respiratory allergy around the world. The problem could be aggravated because in desert or desert-like countries, these weeds are used in greening programmes or as ornamental plants. As climate tendencies should maintain in future decades, relevance of Chenopodiacea/Amaranthacea pollen allergy will go up. Relationship between airborne p...
