Abstract

The objective of this work was to investigate the effect of selenium (Se) on the biomass production and the contents of photosynthetically active pigments. The pot experiment included two maize genotypes: hybrid 408BC originating from Croatia and a local maize population from Kosovo. The doses of Se applied were 0, 1.30, 6.57, 13, and 26 mg kg−1. The lowest Se dose (1.30 mg Se kg−1) had a positive effect on shoot and root biomass production as well as on the contents of chlorophyll b (Chl-b), total chlorophyll, and carotenoids (just for the hybrid). Chlorophyll a (Chl-a) was reduced with increasing Se doses, whereas chlorophyll b (Chl-b) and total chlorophyll further increased with medium Se doses. The highest Se dose strongly reduced biomass and the contents of photosynthetically active pigments. Chl-a and carotenoids positively correlated with shoot (for both genotypes) and root (for the hybrid) biomass, whereas no correlation was observed between Chl-b and biomass. Low amounts of Se application are favorable for biomass production and chlorophyll and carotenoids contents, whereas high amounts of Se application negatively affect both.
