The oil crisis of the last decades of the twentieth century has led researchers to turn their attention to alternative sources of energy, the so-called green energy. One of the genres intensively studied for bi-omass production was the genus Salix. In Europe, in Sweden, were made the first Salix hybrids for short-rotation crops (SRC). Willows are u...

The need of knowledge on bioremediation and ecological reconstruction technologies and their application in environmental degradation consists in achieving of the objectives regarding the remediation of soils and waters contaminated by anthropogenic activities, especially industrial ones. The general goal is sustainable use and development of natur...

The sustainable approach to reducing pesticide pollution by using mycoremediation methods also aims to monitor and give equal importance to all ecological categories of organisms installed on degraded lands with maximum risk, because only a specific diversity in the ecosystem can guarantee its stability, its chances of evolution, and implicitly the...

Chamaecyparis lawsoniana (A. Murr.) Parl. is famous for its great diversity of ornamental cultivars. The vegetative propagation aims at their conservation and use in the design of the gardens and parks. For this reason one-year-old stem cuttings were used from 5-year-old individuals of 'Columnaris', 'Potentii', and 'Golden Wonder'. They were collec...

Chronic pelvic pain syndrome (CPPS) can be triggered by a various types of gynecological, gastrointestinal, urological, and musculoskeletal disorders. Recently, the role of the central nervous system has proven to be an integral part on the development of any chronic pain syndrome, including CPPS. However, owing to the complex and heterogeneous eti...

In Romania, the interest for biomass production from short rotation coppice (SRC) is at beginning, being focused on the culture of poplar and willow. The high productions of biomass, which can be obtained from these cultures, are affected by numerous diseases and harmful insects, with negative effects on viability and vitality of these cultures. In...

Salix is an important energetic genus, but most of the genotypes are closely related genetically, due to frequent natural hybridisation in nature. Therefore it is of great interest to study its genetic background. In this work a collection of progenitors (Romanian accessions) collected from different locations were investigated to determine their g...

The use of bioenergy are increasing in many European countries and an important role will be played by biomass produced in willow SRC.
