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
