| Cadmium (Cd), a heavy metal can be easily incorporated into the food chain due to its high mobility in soil-plant system and thus hazardous for plant, animal and human health. Cadmium, accumulated by plants, causes the degradation of many metabolic activities such as protein synthesis, nitrogen and carbohydrate metabolism, enzyme activation, photosynthesis and chlorophyll synthesis. In this study, the effects of increasing Cd doses (0, 2.5, 5 and 10 mg Cd kg-1) on nicotine, reducing sugar and phenolic compounds of Xanthi/2A tobacco variety were investigated under greenhouse conditions. The experiment was laid out in a completely randomized design with four replications. All matured tobacco leaves were harvested in three hands and dried at sun. The Cd, nicotine, glucose, fructose, chlorogenic and rutin concentrations of leaf samples were determined. The increasing Cd application to soil (P< 0.05) significantly increased the Cd concentration of tobacco leaves. The nicotine concentration which is very important alkaloid component of tobacco was significantly (P< 0.05) reduced by increased Cd application. The nicotine concentrations in control conditions decreased from 4.21 mg g-1 to 3.54 mg g-1 with Cd 10 treatment. Reducing sugar concentration (glucose and fructose) of tobacco leaves significantly (P< 0.05) varied with Cd application. Increasing Cd application resulted in an increase in measured glucose and a decrease in fructose concentrations (especially at the dose of Cd 10) of tobacco leaves. The results revealed that tobacco leaves grown under Cd toxicity conditions accumulate high levels of Cd which cause significant … |
