Abstract

Zinc (Zn) and Copper (Cu) are essential elements and increased plant growth in low concentrations. While high concentrations of these elements as a limiting factor, can cause adverse symptoms on the plants. In the present study, the uptake of Micronutrient and macronutrient by pennyroyal were studied in a Zn and Cu deficiency and toxicity in soil. Three levels of Copper (0, 5 and 25 mg/Kg) and three levels of zinc (0, 10 and 50 mg/Kg) and combination of all the above levels, were used as treatments in a factorial experiment based on completely randomized design with three replications. According to the results, the maximum value uptake of Cu (317.4 µg pot-1) and Zn (1818.27 µg pot-1) in shoots was obtained in Cu25Zn10and Cu5Zn50 treatment, respectively. The maximum values uptake of Fe and Mn (3674.12 and 1537.41 µg pot-1) and P and K (21.88 and 380.52 mg Pot -1) in shoots was revealed in Cu5Zn10 treatment. The highest values uptake of Cu, Zn, Fe and Mn in root (281.33, 1802.85, 18744.4 and 1235.68 µg pot-1, respectively), P (22.56 mg pot-1) was observed in Cu25Zn50 treatment and K (115.94 mg pot -1) in Cu5Zn50 treatment. It could be concluded that pennyroyal herb has the high ability to absorb and transfer of elements to shoots. So, use pennyroyal grown in soils contaminated with Cu and Zn due to uptake and transport of these elements to shoot would be required with caution.
