Growth performance of selected eucalypt hybrid clones for SRWC in central and southern Italy


Abstract


Eucalypt short-rotation woody crop (SRWC) is becoming an attractive option for energy biomass in Mediterranean dry environments. The present study is aimed at assessing growth performance of selected eucalypt hybrid clones for SRWC in three Italian sites (Massama, Sardinia; Mirto, Calabria; Rome, Latium) compared with Eucalyptus camaldulensis, the most commonly cultivated eucalypt species in Italy. The study identified eucalypt clones with stable and high performance between several alternatives. Results pointed out the declining growth performance observed in the second rotation compared with the first cycle. This is due to the cultivation model, age rotation and harvesting method adopted, which negatively affect the available soil nutrients’ content. The clone/site interaction as for basal area growth at the three investigated sites, suggests a significantly different clones’ performance among sites. Viglio and Velino clones showed the best overall performance and are suggested to be used over the large scale SRWC in central and southern Italy.
