|
Heavy metals can cause long-term harmful effects on ecosystem health. Some heavy metals are essential microelements for plants' development and growth, such as zinc (Zn), copper (Cu), manganese (Mn), iron (Fe), and nickel (Ni). Cadmium (Cd), Hg, Pb, Cu, and As are some of the most toxic heavy metals or metalloids found to induce serious poisonous effects on plants such as growth retardation, destruction of chlorophyll, disorders in biochemical activities, mutations, reproductive disorders, disruption of cellular osmoregulation and the degradation of proteolytic activities, heavy metals cause inhibition of seed germination and seedling development. And adversary influence quantitatively and qualitatively the composition (function and diversity) of microbial communities, leading to substantial changes in ecological dynamics of the rhizosphere niche.

| Experiment Detail |
One year-old uniform and well-rooted plants (45 cm height) of mandarin orange (raised in sand bed nursery), were transplanted in earthen pots (12″ diameter) filled with well-sieved acid-washed sand. Plants were supplied with 1/10 strength of MS solution (pH 5.6) every alternative day. Seven weeks after transplanting, the stress treatment was applied for 14 weeks until pronounced visual structural indications of stress (e.g., chlorosis of leaves, growth impairment etc.) appeared. On every alternate day, each pot was fed with 500 ml of 1/10 strength MS solution (pH 5.6) together with ZnSO4 solutions containing 1 mM, 2 mM, 3 mM, 4 mM, 5 mM, 10 mM, 15 mM and 20 mM of Zn. Without Zn (0 mM Zn) was served as the control.

| Factor Function |
Zn stress reduced the photosynthetic rate, stomatal conductance, and transpiration along with reduction of chlorophyll a, chlorophyll b, and carotenoids content in leaf.
