| endogenous gibberellins in elongating shoots of clones of salix dasyclados and salix viminalis. | elongating shoots of rapidly growing clones of salix viminalis l. (clone 683-4) and salix dasyclados wimm. (clone 908) harvested in early august were analyzed for endogenous gibberellins (ga). distribution of ga-like activity, determined by tan-ginbozu dwarf rice microdrop bioassay after reverse phase c(18) high performance chromatography, was similar for both species. for s. dasyclados, combined gas chromatography-selected ion monotoring (gc-sim) yielded identifications of ga(1), ga(8), ga(19), ... | 1988 | 16666223 |
| 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 |
| hydroponic screening for metal resistance and accumulation of cadmium and zinc in twenty clones of willows and poplars. | we screened 20 different clones of willow and poplar species in hydroponic experiments for their metal resistance and accumulation properties. plants were exposed for 4 weeks either to single additions of (microm) 4.45 cd or 76.5 zn, or a metal cocktail containing the same amounts of cd and zn along with 7.87 cu and 24.1 pb. plant biomass, metal tolerance and metal accumulation pattern in roots and leaves varied greatly between clones. the leaf:root ratio of metal concentrations was clearly unde ... | 2007 | 17241723 |
| a comparison of phytoremediation capability of selected plant species for given trace elements. | in our experiment, as, cd, pb, and zn remediation possibilities on medium contaminated soil were investigated. seven plant species with a different trace element accumulation capacity and remediation potential were compared. we found good accumulation capabilities and remediation effectiveness of salix dasyclados similar to studied hyperaccumulators (arabidopsis halleri and thlaspi caerulescens). we have noticed better remediation capability in willow compared to poplar for most of the elements ... | 2006 | 16516363 |
