摘要

Optimizing the supply of woody biomass from dedicated crops is a key factor for ensuring raw materialrnthat will enable the development of the bioeconomy in Europe while contributing to the mitigation of climaternchange.The aim of this work is to characterize the productive response of the second rotation crop as well as itsrnstability under different Mediterranean environments in plantations which include different genotypes suitable forrncoppice.These are: Populus spp. (Populus deltoides clone`Baldo´, Populus x canadensis clones: `Orion´,rn`Oudenberg´, `Ballottino´ and `I-214´), Salix matsudana x Salix spp. (`Levante´), Robinia pseudoacacia (`Nyirsegi´)rnand Platanus x hispanica (`Girona´). The plantations, established in 2009 with 10,000 trees per hectare, will bernassessed at the end of the second rotation, with six years of root growth and three of stem growth (R6S3). Arnmultifactorial analysis of variance is used to evaluate the response of genotypes and environments for the dry biomassrnproduction under three different conditions.This analysis is complemented by the examination of the mean genotypicrnvalue along with the variability in clonal productivity.Since genotypic stability is an important issue in furthering ourrnunderstanding of the plant material, a GGE biplot was performed to analyse the genotypic and environmentalrnbehaviour, as well astheir interaction. Significant differences in production were observed as well as different trendsrnin the productive response stability, allowing us to assess the suitability of the different species for this productivernpurpose in the Mediterranean area.
