“…The presented (2007), willow growth and phytoextraction efficiency were significantly plant species dependent. We can suggest that some other willow species/ varieties that we tested in our other work (Mleczek et al 2010) may be most interesting to use in phytoextraction of copper polluted areas. In addition, Dos Santos Utmazian et al (2007) reported differences in plant biomass, metal tolerance and metal phytoextraction between willow clones.…”

This work reports a part of hydroponic experiment results concerning changes in Salix viminalis L. cv. 'Cannabina' morphology and physiology under stress conditions with different copper concentration levels and verifies our earlier results about the role of different Ca/Mg ratios in trace elements' accumulation efficiency. In this part, we present the copper accumulation and changes in willow biomass. Concentration of copper in roots, rods, shoots and leaves was analyzed with flame atomic absorption spectrometry. Selected indices characterizing copper accumulation and plant biomass structure were calculated to estimate the potential of willow to remove metal from polluted solution. Our results indicate a general increase of copper accumulation by selected willow organs with increase of copper concentration in modified Knop's medium. Moreover, significant differences in copper phytoextraction between plants under different Ca/Mg ratios were affirmed (1:10 [ 4:1 [ 20:1 [ 1: 1 / 4 ).

“…Willows also seem to have outstanding potential for the production of bioenergy [1]. Several species and hybrids can absorb metals or organic compounds and therefore could be used for phytoremediation [2][3][4]. The species Salix viminalis has potential of being an energy-crop [5].…”

Biotechnological methods of in vitro propagation in willows (Salix spp.)

Many populations of high-mountainous relic dioecious willows in Central Europe only consist of female individuals and are thus limited in their reproductive potential. We completed micropropagation experiments with shoot apexes and nodal segments of common and endangered willow (Salix) species, which can help to reintroduce autochthonous genotypes to their natural sites. Until recently, cultivation of green young shoot apexes of S. alba and S. lapponum showed the highest percentage of regeneration. We successfully applied the two-times-sterilisation due to high contamination of natural explants. The OK medium was the most efficient culture medium. In vitro propagation of willows with unisexual catkins, anther and ovule cultures were tested and optimised. Isolated anthers were cultivated on selected media and then microcallus and calluses of S. caprea and calluses of S. viminalis were formed on the A medium. Among various tested and optimised media for the ovule culture, the CP medium was the most efficient one. In this case, only the microcalluses of S. viminalis were observed. We developed biotechnological procedures that can be useful in conserving fragmented populations of high-mountainous willows.

“…While hydroponic experiments have been undertaken to study plant tolerance to a range of chemicals or to gather information about the synthesis of root exudates [29,30], information from hydroponic experiments for selecting energy crops, or even SRC planting material is very limited. However, this can add valuable information about particular clone preferences and shortages.…”

Abstract:The production and feasibility of Short Rotation Coppice depend on cutting early performance. The shoot and root biomass production of Salix cuttings in hydroponic conditions was studied. The amount of sprouted biomass after four weeks of growth depended on cutting the diameter, but the original position of the cutting along the rod or number of visible buds was not in correlation with biomass produced. Application of mineral fertilizer or soil originating from the willow plantation did not increase the total production. On the contrary, the addition of soil tended to decrease biomass production and we assumed this was a result of a shortage of light. Under the influence of fertilization, plants allocated greater biomass to roots. Comparison of different clones revealed that those with S. dasyclados genes tended to allocate less biomass to roots and the poorest-performing clone in our experiment, also had the lowest wood production in the plantation. The number of visible buds on the cutting was also clone-specific.
