dc.description.abstract | The increased bioeconomy targets for the biomass share of renewable energy production across Europe
should be met using land unsuitable for food production. Miscanthus breeding programs targeted the
production of plants with a diverse range of traits allowing a wider utilization of land resources for
biofuel production without competing with arable crops. These traits include increasing tolerances to
drought, chilling, and to metal(loid)s excess. Two novel Miscanthus hybrids, GNT41 and GNT34, were
compared against Miscanthus x giganteus (Mxg) on metal-contaminated arable land in Poland. This study
aimed at evaluating their yield, biomass quality and quantifying seasonal differences in photosynthetic
and transpiration parameters. A secondary objective was to identify key physiological mechanisms underlying
differences in metal accumulation between the investigated plants. The new hybrids produced a
similar yield to Mxg (13e15 t ha 1 yr 1), had shorter shoots, higher Leaf Area Index and stem number.
Based on gas exchange measurements, GNT34 exhibited isohydric (water-conserving) behavior. The
stomatal response to light of the new hybrids was at least twice as fast as that of Mxg, a trait that is often
associated with increased seasonal water use efficiency. This contributed to the almost 40% reduction in
shoot Pb and Cd concentrations for the new hybrids as compared to Mxg. This suggested that promoting
stomatal regulation in conjunction with improved water conservation may be a target for improving
plants for wider use on metals contaminated land. | pl_PL |
