In the years 2000-2003, a field experiment with 21 genotypes of Salix spp. willow was conducted. The aim of the research was to examine the possibility of cultivating the plant on arable lands, as a stable and reliable source of high quality herbal raw material. The research demonstrated the need to choose the S. purpurea and S. alba species for cultivation on arable lands in order to obtain a high quality bark. The most valuable genotype for the production of herbal raw material proved to be S. purpurea 1101, which provided a high yield of fresh mass of bark (5.27 t/ha) and demonstrated a high salicin content (1.73%), when planted with a population density of 200,000 plants per 1 ha. An additional advantage of cultivating the willow on arable lands is the possibility of the versatile use of their biomass. The shoots that remain after debarking (using the bark for herbal purposes) could provide, for instance, valuable material for basket-making. Such a usage could provide a source of additional income for a willow plantation focused on producing herbal raw material.

The objective of the study was to evaluate the content of phenolic glycosides in bark of purple willow [Salix purpurea L.), originated from natural habitats. Special attention was paid to the soil features determining phenolic glycosides concentration in willow bark. The phenolic glycosides content in the purple willow ecotypes on peat soils was the highest (6.00%), whereas on alluvial soils (4.18%) and rendzina type (4.37%) was much lower. The content of phenolic glycosides in Salix purpurea bark in river valley habitats was determined by reaction and the content of Mg and CaC03

The objective of this study was to evaluate the content of phenolic glycosides in willow bark. Salix daphnoides Vill., S. purpurea L. and S. alba L. were taken from their natural habitats. Afterwards, the ecotypes with the highest phenolic glycosides content were used in field cultivation. There was substantial evidence to indicate that violet willow contained the highest amount of phenolic glycosides. Taking into account limited number of its stands violet willow can be regarded as a good source of quality stuff while cultivating. The ecotypes of Salix daphnoides and S. purpurea were selected for the study to be used in field cultivation. As a result the concentration of salicylates was much higher than in their natural habitats.
