They are important constituents of protoplasm and cell wall e.g., sulphur occurs in proteins, phosphorus in nucleoproteins and adenosine [...]
In this article we will discuss about the roles of micronutrients elements in plants. 1. Manganese: Manganese is required in very low concentrations as its high concentrations become toxic to plants. It is abundant in the physiologically active parts of the plant especially leaves and it is relatively immobile. It is an activator of enzymes involved in respiration and nitrogen [...]
