摘要

Willow gives us a lot of possibilities of using it in the protection of the environment. Nowadays this plant is an object as an energetic plant and the plant used in phytoremediation and is characterized by fast growth, high production of wood and high tolerance to accumulate heavy metals. The influence of sewage sludge on the growth, morphological traits and yield of four selected clones of Salix viminalis and its halfbreeds is presented in the paper. The experiment with willow and sewage sludge was carried out at the Experimental-Didactic Station in Wroc?aw in 2008-2010. The experiment with the clones of willow was established in 2003. Split-plot method was applied in three repetitions with two changeable factors. Analysis showed a significant influence of weather conditions, various doses of sewage sludge and genetic properties of clones on yield, the number and length of shoots and diameter. The highest productivity of clones concerned the object with a double dose of sewage sludge. Clone 1054 was characterized by the highest productivity and was the best biometric traits.
