This paper presents an investigation of the capacity of four different plants to remove and assimilate ferri-cyanide at different pH conditions. Detached roots of weeping willows (Salix babylonica L.), rice (Oryza sativa L. cv. JY 98), soybean (Glycine max L. cv. WH) and maize (Zea mays L. var. HK) were hydroponically exposed to ferri-cyanide in a closed system at 25 ± 0.5 C for 24 h kept under...

Plagiodera versicolora, a willow beetle living on S. sachalinensis, is found on S. integra during early June in Hokkaido Island, Japan. This insect selects several species of willows (Salix), including S. integra as host plant in Honshu Island of Japan. To determine the reasons for the limited distribution of this beetle on the willows of Hokkaido, the feeding preference of the insect to leaves...

Measurements of the statistical characteristics of umbra and sunflecks at different depths inside a willow coppice — Salix viminalis and Salix dasyclados — were carried out at Tartu Observatory, Tõravere, Estonia, in 1997. A new instrument, the sunfleck indicator, constructed by M. Sulev, was used. This instrument, moving perpendicularly to rows in the horizontal direction, counts the number an...

An earlier identified major quantitative trait locus for resistance towards the willow leaf rust fungus Melampsora larici-epitea in a Salix viminalis x (S. viminalis × S. schwerinii) population was used to identify potential resistance genes to the rust pathogen. Screening a genomic bacterial artificial chromosome library with markers from the peak position of the QTL region revealed one gene w...

Western European coastal sand dunes are highly important for nature conservation. Communities of the creeping willow (Salix repens) represent one of the most characteristic and diverse vegetation types in the dunes. We report here the results of the first kingdom-wide fungal diversity assessment in S. repens coastal dune vegetation. We carried out massively parallel pyrosequencing of ITS rDNA f...

Plants' uptake and metabolism of cyanide in response to changes in temperature was investigated. Pre-rooted weeping willows (Salix babylonica L.) were exposed to hydroponic solution spiked with potassium cyanide for 2-3 d. Ten different temperatures were used, ranging from 11 degrees C to 32 degrees C. Cyanide in water, plant tissue, and air was analyzed spectrophotometrically. The results reve...

WALKER, D. A. 1987. Height and growth rings of Salix lanata ssp. richardsonii along the coastal temperature gradient of northern Alaska. Can. J. Bot. 65: 988-993. Salix lanata ssp. richardsonii from open-tundra and streamside populations were studied at seven sites along a 100-km north-south transect following the Sagavanirktok River from the Alaskan arctic coast to the foothills of the Brooks ...
