Willows are fast-growing species with a large capacity for sprouting and easy breeding. In order to identify Salix accessions suitable for different conditions, a willow plantation was established in the Didactic Station of BUASVM from Timisoara, Timis County, Romania. 19 Salix genotypes (nine species: Salix alba L., S. cinerea L., S. caprea L., S. daphnoides L., S. fragilis L., S. incana L., S. purpurea L., S. pentandra L., S. triandra L.) were collected from a polluted area (copper and uranium mining area) but also from old willow farms, all from Caras-Severin County. The sprouting capacity and biometric observations were made in an experimental trial with uncut and cutback shoots and biomass was estimated after one growing season. Large variability was observed in terms of survival rate but also the number of shoots per stool, maximum height, and diameter. To evaluate the tolerance of heavy metal stress, four accessions were selected and a laboratory experiment was developed. The enzymatic activity varied according to with stress abiotic factor and also with genotype.
