چکیده
Phytoremediation is a method in which plants are used to absorb contaminants. Heavy metals significantly affect plant distributions by competing with nutrients and limiting plant growth. In this study, three-year-old seedlings of Crataegus aronia and Juniperus polycarpos were exposed to different concentrations of zinc nitrate (0, 50, 250, and 500 ppm) in a completely randomized design with three replications. Then, the amount of zinc uptake in different organs of Crataegus aronia and Juniperus polycarpos seedlings was measured by atomic absorption spectroscopy after acid digestion and total chlorophyll content was measured with a spectrophotometer after extraction. The results obtained from the analysis of variance showed that in both species, zinc accumulation increased in roots and stems with increasing heavy metal concentration and that zinc accumulation was higher in root tissues than stem tissues in all treatments (p<0.05). In addition, zinc contamination decreased the concentration of all nutrients content in leaves and stems of seedlings, and total chlorophyll decreased by 56% in Juniperus polycarpos and 47% in Crataegus aronia. Accordingly, it can be said that the seedlings of Crataegus aronia and Juniperus polycarpos have the ability to prevent the transfer of the metal to aerial parts and to lower its toxicity to the plant by accumulating zinc in the roots. It should be noted that Juniperus polycarpos was a better accumulator of zinc than Crataegus aronia by 33%.
