Zinc sulfate and Zn oxide had higher total phenols than Zn-EDTA, and these are the sources of Zn that increased Zn accumulation in pea microgreens . Zinc concentrations of 25 ppm had lower antioxidant activity than 50, 100, and 200 ppm. All the treatments had similar total phenols compared to the control.

Zinc (Zn) is an essential component of thousands of proteins in plants, although it is toxic in excess. In this review, the dominant fluxes of Zn in the soil-root-shoot continuum are described, including Zn inputs to soils, the plant availability of soluble Zn(2+) at the root surface, and plant uptake and accumulation of Zn.

The findings indicate that Zn-NCDs can provide a sufficient amount of zinc for plant absorption. The highest zinc concentration was found in Zn-NCDs treatments (Table 5). Zinc concentration in grains treated with Zn-NCDs1 was 18.67 times higher than the zinc concentration in grains treated with ZnSO 4. The amount of zinc in the grain …

The essentiality of Zinc (Zn) for plant growth and development is not a new message. Zn is the second most common transition metal in living organisms, after iron (Fe) (Marschner 2012).Because zinc has structural, catalytic, and active properties, it is necessity for plant growth, reproduction, and signaling (Mousavi et al. 2018b).Zinc is …

Zinc and Plant Growth. The function of zinc is to help the plant produce chlorophyll. Leaves discolor when the soil is deficient in zinc and plant growth is stunted. Zinc deficiency causes a type of leaf discoloration called chlorosis, which causes the tissue between the veins to turn yellow while the veins remain green.

Zinc is one of the most important micronutrients required for optimal plant growth and productivity. Paradoxically, a higher concentration of the same can be toxic for the plants, and hence, a constant supply of zinc to maintain an optimal intracellular concentration in plants is required which is referred to as zinc homeostasis.

Such species tend to amass Zn at high concentrations within a plant which doesn't harm the plant but rather can cause toxicity to pathogens in case of infection and serves as a defence factor (Helfenstein et al., Citation 2015). This may not be the situation in all plants since Zn hyper level may be toxic to certain plants.
