Micronutrients: The Cornerstones of Plant Physiology

Here are the key roles of Micronutrients, which are required in small quantities for physiological processes in plants and their deficiency symptoms

Let’s explore the specific contributions of these micronutrients

Iron is a key component of chlorophyll, deficiency manifests as chlorosis

Iron (Fe)

Zinc (Zn)

A hormone regulating plant growth and development, deficiency can lead to stunted growth, delayed maturity, and reduced yield.

Copper (Cu)

It is involved in photosynthesis, respiration, & carbohydrate metabolism, deficiency can cause wilting & dieback of shoot tips

Manganese (Mn)

Plays a vital role nitrogen assimilation, and disease resistance, deficiency leads to increased susceptibility to fungal diseases.

Molybdenum (Mo)

It is a cofactor for nitrogenase, an enzyme crucial for nitrogen fixation in legumes, deficiency can cause whiptail in cauliflower

Boron (B)

Essential for cell wall formation, pollen tube growth, & carbohydrate translocation, deficiency leads to fruit cracking & distorted leaves

Chlorine (Cl)

Involved in osmoregulation & stomatal function, deficiency  leads to reduced photosynthesis & increased susceptibility to water stress

Conclusion

Though required in smaller quantity, Micronutrient deficiencies have higher impact on plant growth leading to reduced yield & profitability
