Abstract
Do oksidacijskog stresa u biljnim stanicama dolazi zbog akumulacije reaktivnih kisikovih jedinki (ROS). Biljke su razvile dva obrambena sustava na povišene koncentracije ROS-a; enzimski i neenzimski. U ovom je radu proučavan antioksidacijski odgovor vrste japanski dvornik (Reynoutria japonica Houtt.) na stres izazvan izlaganjem niskoj temperaturi (5 ºC) u različitim vremenskim intervalima (4, 16 i 48 sati). Kratkotrajno izlaganje biljaka niskoj temperaturi (4 sata) dovelo je do povećanja koncentracije karotenoida i smanjenja intenziteta lipidne peroksidacije (TBARS) ukazujući na učinkovitu zaštitnu ulogu karotenoida. Dugotrajnije izlaganje niskoj temperaturi (16 i 48 sati) uzrokovalo je povišenje koncentracije vodikovog peroksida što je dovelo do aktivacije antioksidacijskog odgovora koji ipak nije bio dovoljni učinkovit da spriječi oštećenja biomembrana.
Abstract (english)
Oxidative stress in plant cells is caused by accumulation of reactive oxygen species (ROS). Plants have developed two systems of defence response to increased concentrations of ROS; enzymatic and non-enzymatic. This study took a look at antioxidative response of Japanese knotweed (Reynoutra japonica Houtt.) to stress induced by exposure to low temperature (5 ºC) in multiple time periods (4, 16 and 48 hours). Short-term exposure of plants to low temperature (4 hours) led to an increase in the concentration of carotenoids and a decrease in the intensity of lipid peroxidation (TBARS) indicating an effective protective role of carotenoids. Prolonged exposure to low temperatures (16 and 48 hours) caused an increase in the concentration of hydrogen peroxide which led to the activation of an antioxidant response which however was not effective enough to prevent damage of biomembranes.
