| Popis: | Under EU legislation, energy crops must be grown on marginal land. Sida hermaphrodita L. Rusby is one of the promising perennial energy crops. The study aimed to investigate the physiological status of S. hermaphrodita mature plantations growing on two different marginal lands - one contaminated with heavy metals (M) and one nutrient-poor sandy soil (NM). On the second marginal land, two different harvesting practices have been carried out since establishment: one harvest (NM1) and two repeated harvests (NM2) of biomass each year before the experiment. Measurements were made of gas exchange, chlorophyll a fluorescence, plant pigment content, canopy architecture, growth parameters, and biomass yield. A higher biomass yield (2-fold) was found on the M site compared with both treatments on the NM site. It could be concluded that soil quality was the main reason for the higher yield at M site. S. hermpaphrodita being a heavy metal excluding plant is a more suitable option for fertile but heavy metal polluted soils than nutrient-poor soils, however, biomass quality should be further investigated. |
