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

Abstract: 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.
