INTERSPECIFIC VARIABILITY OF SOME ACCESSIONS OF SALIX SP. COLLECTED FROM OLTENIA REGION, ROMANIA

The Salix genus includes many species with various uses: wood production, biomass, animal feed, source of salicylic acid, land reclamation, biofuel, a.o. In order to establish a collection potential genitors, resistance genes stressors, 39 accessions were collected in 2015 from Banat and Oltenia, Romania. This paper presents an evaluation 20 accessions, belonging 7 species, polluted or degraded lands Oltenia. intra- interspecific variability, analyzed through the prism production characters for SRC, is significant. study gives possibility selecting some valuable breeding strategy creation new forms more adapted environmental challenges. best results regarding biomass sprouting capacity growth rate recorded by S. triandra, viminalis, fragilis.
