the cecidomyiid species rabdophaga heterobia (loew) induces gall on willow's male catkins, and causes small rosettes at the extremities of shoots and swollen lateral buds or lateral rosettes on some species of willow. during the years 2006-2007, a study on willow pests in the west azarbaijan province (saatloo poplar research station) was conducted. the following nine willow species were us...

Plants whose morphological characteristics correspond to those of Orobanche filicicola Nakai ex Hyun, Lim et Shin as described by (1952) and validated Huyn al. (2003), were in 2012 found for the first time Russia (Far East, Primorye Territory) growing on banks Ussuri River Chuguyevsky District a mixed population with O. amurensis (Beck) Kom. SE flank Sikhote-Alin Mountains (Lazovsky District). ...

Shrub willow, Salix spp. and hybrids, is an important bioenergy crop. Here we report the whole-genome sequences and annotation of 13 endophytic bacteria from stem tissues of Salix purpurea grown in nature and from commercial cultivars and Salix viminalis × Salix miyabeana grown in bioenergy fields in Geneva, New York.

Onshore sediment transport and sandbar migration are important to the morphological evolution of beaches but are not well understood. Here, a model that accounts for fluid accelerations in waves predicts the onshore sandbar migration observed on an ocean beach. In both the observations and the model, the location of the maximum acceleration-induced transport moves shoreward with the sandbar, re...

BACKGROUND Little is known about the levels of variation in lignin or other wood related genes in Salix, a genus that is being increasingly used for biomass and biofuel production. The lignin biosynthesis pathway is well characterized in a number of species, including the model tree Populus. We aimed to transfer the genomic resources already available in Populus to its sister genus Salix to ass...

Under climate change, shrubs encroaching into high altitude plant communities disrupt ecosystem processes. Yet effects of encroachment on pollination mutualisms are poorly understood. Here, we probe potential fitness impacts of interference from encroaching Salix (willows) on pollination quality of the alpine skypilot, Polemonium viscosum. Overlap in flowering time of Salix and Polemonium is a ...

Carbon, hydrogen and sulphur were determined in biomass (shoots and roots) of five species of shrub willow: Salix viminalis, Salix dasyclados, Salix triandra, Salix purpurea and Salix alba. Samples of the biomass collected from a strict experiment were dried to constant weight at 105oC. The content of carbon, hydrogen and sulphur was determined in an automatic determinator ELTRA CHS 500. In add...
