Phytoremediation of Metal Contamination Using Salix (Willows)
… willows native to the Rocky Mountains: <em>Salix drummondiana</em>, <em>S. monticola</em>, and <em>S. planifolia</em>. I tested the willows’ accumulation and tolerance characteristics of cadmium and lead contamination. I found that <em>S. drummondiana</em> accumulated more cadmium in stems …

Floral Scent in Salix L. and the Role of Olfactory and Visual Cues for Pollinator Attraction of Salix caprea L.
… composition of floral scent of different Salix species as well as its inter- and intraspecific variability were analysed. The role of floral scent for attracting flower visitors was examined in S. caprea by means of electroantennographic studies and bioassays. The relevance of different …

MULTIPLE APPROACHES TO MAPPING RESISTANCE TO MELAMPSORA LEAF RUST IN SHRUB WILLOW (SALIX)
… Most of the research into the Melampsora and Salix pathosystem centers around European species, however, revealing a need for the characterization of resistance of their North American counterparts. Two mapping populations have been generated for the species S. purpurea, which has high quality …

The potential of Short Rotation Coppice (SRC) willow (Salix L.) as a biomass crop in Orkney.
… in the maritime climate of Orkney, SRC willow (Salix spp.) is a proven alternative woody biomass crop which can be grown as a local renewable fuel. A selection of 13 SRC clones were screened in Orkney and the most promising six clones which are recommended in Orkney are Ashton Stott, Tora, Sven, …

The Genomic Basis of Heterosis in High-Yielding Triploid Hybrids of Willow (Salix spp.) Bioenergy Crops
… bioenergy crops such as shrub willow (Salix spp.), can help offset fossil fuel usage without competing with food crops. Hybridization is a key component in shrub willow breeding because hybrids often exhibit heterosis for yield. The genomic basis of heterosis in willow has not been well …

Fungal Flora of a Cove on Lake Falcon
… stems of Arundo donax, Prosopis glandulosa, and Salix nigra which were collected monthly. The leaves of Salix nigra were also collected monthly for observed Aquatic Hyphomycetes. A measurement of the fungal biomass on Arundo donax would be determined by a survey of numbers of ascoma on the stems. …
