ABSTRACT

Energetic crops are increasingly used as renewable sources of energy as well as for their ability to fix and accumulate carbon in the soil. Willow culture for biomass promotes rural development and environmental protection, especially if it is established in areas less favorable for agricultural crops.
Researches from this work has been carried out in a wide range of genotypes of Salix sp. cultivated on a deposit of ash resulting from coal burning to Isalnita Power Station, near Craiova, Romania, over a period of two years of vegetation. Determinations were made regarding plants growth and development such as stem height, no. of shoots/plant and stem diameter at the base, as well as on the development of the root system, determining the number and weight of roots.
The results were statistically interpreted by analysis of variance method, LSD 5%, and the principal components analysis. Hydric stress is one of the main factors of limiting plant growth on this type of artificial substrate and the experimented willow genotypes have reacted differently. It emphasizes with good results in terms of the quantity of biomass RO 1077, Fragisal, Robisal and Torhild genotypes.
An interesting phenomenon as concern root morphology, on the ashes from Isalnita is that there were identified many side branches especially in the 0-20 cm, with a thin appearance.
