Sažetak
Cadmium is a heavy metal present in vast array of ecological habitats including those intended for maize production. It is known that cadmium is detrimental for plant growth and health affecting photosynthetic performance. The aim of our study was to capture the effects of cadmium on maize photosynthetic performance during and after the growth crisis stage marking the transition of plant to autotrophic state. In this study, effects of different concentrations of cadmium on plant physiology and development in the early stages of maize plant growth were determined through the measurement of photosynthetic parameters as well as chlorophyll content. Two maize inbreds and their hybrid were grown under controlled conditions in a growth chamber and measured six times during four-week growth period in control (Co), 150 mg/kg (Cd150) and 375 mg/kg soil Cd (Cd375). Both Cd treatments significantly reduced plant biomass. Photosynthetic performance was not reduced until 14th day after sowing when the growth crisis is expected to occur, while from 15th to 28th day after sowing, steady decrease in photosynthetic performance was observed. Implications of these results will be discussed.
