| leaf litter ecological fate in the schelde estuary in belgium. | two dominant species of willow(salix triandra) and reed (phragmites australis) along the schelde estuary(in belgium) were selected in this research. the pigments of higher plant was used as biomarkers, the decomposition process of the two species were studied after they fall into the schelde estuary. after statistical analysis (spearman rank order correlation, p < 0.05), the results has shown the decomposition dynamics pattern of the pigments, and the willow showed different pattern in comparing ... | 2002 | 12491734 |
| cryopreservation of salix species using sections from winter vegetative scions. | twigs of salix species are candidates for cryopreservation procedures because they become tolerant of freezing temperatures during mid-winter. we examined several variables in developing a two-step cryopreservation procedure for sections from these twigs. samples of salix triandra cooled to -30 or -35 degree c and then transferred to the vapor phase over liquid nitrogen gave the greatest percent shoot formation. cooling rate to -35 degree c had a major influence on shoot formation. samples coole ... | 2004 | 15031747 |
| decomposition dynamic of higher plant pigments by hplc analysis. | the fate of the litter of dominant vegetation(willows and reeds) is one of the aspects studied in the frame of the project "onderzoek milieu effecten sigmaplan". one of the questions to be considered is how long the litter stays within the estuary. in this paper, the time the leaf litter (salix triandra and phragmites australis) stayed in the schelde estuary was studied by using plant pigment as biomarkers with hplc application. after analyzing the original data from the incubation experiment de ... | 2004 | 15559826 |
| application of high-performance liquid chromatography for research of salicin in bark of different varieties of salix. | willow (salix l.) species are widely spread in lithuanian natural dendroflora. willow bark contains active substances known for anti-inflammatory properties and is known as a phytotherapeutic precursor of aspirin. bark extracts are components of analgesic and antirheumatic preparations. therapeutic effectiveness is associated with salicin (2-(hydroxymethyl)phenyl-beta-d-glucopyranoside), which turns into salicylic acid. increasing attention to natural preparations gives primary importance to res ... | 2009 | 19773624 |
