Abstract

Jedan od vaţnijih problema današnjice predstavljaju teški metali, posebice kadmij, koji se nalaze u tlu i mogu ući u hranidbeni lanac što bi moglo biti pogubno za sva ţiva bića. Iz tog razloga sve više se proučava fitoremedijacija - metoda koja koristi biljke kako bi uklonila metale iz tla. U ovom radu promatran je utjecaj kadmija na rast jablana (Populus nigra var. italica), akumulacija i tolerancija kadmija, njegova preraspodjela u pojedine dijelove biljke te utjecaj kadmija na aktivnosti antioksidativnih enzima superoksid-dismutaze (SOD), katalaze (CAT), askorbat-peroksidaze (APOX) i peroksidaze (POD). Dobiveni rezultati pokazuju da bi se jablan (Populus nigra var. italica) mogao uspješno koristiti u fitoremedijaciji kadmija.

Abstract (english)

One of the major problems of today are heavy metals, especially cadmium, which are found in the soil and can enter the food chain, which can be fatal for all living beings. For this reason, phytoremediation – a method which uses plants to remove metals from the soil, is being studied more intensively. This study observes the influence of cadmium on the growth of poplar (Populus nigra var. italica), cadmium accumulation and tolerance, its distribution in certain parts of the plant and the effect of cadmium on the activities of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APOX) and peroxidase (POD). The obtained results show that the poplar (Populus nigra var. italica) can be successfully used for phytoremediation of cadmium.
