Investigation the amount of Zinc pollution on soil resources and the feasibility of its removal with Phragmites australis plant using its extraction cellulose in the greenhouse conditions

Heavy metals cases are threatening the health of ecosystems. Accumulation of metals in the soil allows them to plant crops and thus increases the risk of agriculture crops health. The goal of this research was conducted to evaluate zinc stress resistance for Pharagmites australis in greenhouse conditions.

Experimental design was performed in an entirely randomized plan having two factors and three replications, 2016 at University of Jiroft. Digestion and preparation of samples were done by dry burning method and then Zinc concentration was measured by atomic absorption.

Greenhouse experiments results showed that with increasing in metal concentration treatments, its absorbing with shoot and root were increased. However, impressive accumulation of zinc was in root and its translocation and accumulation in shoot has been reported much less.

With absorb and accumulate of metals in root, ability of plant growth was decreased with changes in physiological characteristics. Results of regression analysis showed concentration increasing of zinc in P. australis organs under these metal stress condition were fitted as a quadratic function with R2 >90 (p<0.01). In summary results of this research show high relatively resistant of P. australis to zinc stress as necessary metal in plants, high accumulation capacity for metal in its root organ and low heavy metal translocation factor.
