Nickel (Ni) is an essential micronutrient for plants, though it is needed in very small amounts compared to macronutrients. Nickel plays a critical role in various physiological processes, growth, and development in plants. It is involved in several enzymatic reactions and influences plant health and overall functionality. Here’s a detailed overview of the roles of nickel in plant growth and development:

1. Enzyme Cofactor and Activation:

  • Nickel acts as a cofactor for several enzymes involved in essential metabolic pathways within plants.
  • It is crucial for enzyme activation and catalysis, influencing various biochemical reactions.

2. Nitrogen Metabolism and Nitrogenase Activity:

  • Nickel is an essential component of nitrogenase, an enzyme involved in nitrogen metabolism, particularly in nitrogen fixation in certain types of bacteria and plants.
  • It helps in converting atmospheric nitrogen into a form that plants can utilize for growth and development.

3. Urease Activity and Urea Hydrolysis:

  • Nickel is a cofactor for urease, an enzyme that catalyzes the hydrolysis of urea to ammonia and carbon dioxide.
  • It influences the efficiency of urea utilization by plants, providing a source of nitrogen.

4. Iron Metabolism and Iron Uptake:

  • Nickel is involved in iron metabolism, influencing the absorption and utilization of iron (Fe) by plants.
  • It supports iron uptake, promoting its movement within plant tissues and enhancing iron utilization for various metabolic processes.

5. Seed Germination and Plant Development:

  • Nickel influences seed germination and early plant growth, playing a role in the development of seedlings.
  • It supports the initial stages of plant growth, ensuring healthy establishment and vigor.

6. Photosynthesis and Carbon Metabolism:

  • Nickel contributes to photosynthesis by influencing the activity of carbonic anhydrase, an enzyme involved in carbon fixation and photosynthetic efficiency.
  • It aids in the conversion of carbon dioxide into bicarbonate ions, a crucial step in the carbon metabolism of plants.

7. Stress Tolerance and Defense Mechanisms:

  • Nickel plays a role in stress tolerance by enhancing the plant’s ability to cope with various environmental stressors.
  • It supports defense mechanisms, aiding plants in their response to biotic and abiotic stress conditions.

8. Floral Development and Pollination:

  • Nickel has been shown to influence floral development, affecting flower structure and fertility.
  • It plays a role in flower maturation and facilitates successful pollination and reproduction.

Balanced nickel levels are crucial for achieving optimal plant growth, development, and productivity. Proper nickel management through appropriate fertilization and soil amendments is essential for sustainable agriculture, ensuring that plants have adequate access to this vital micronutrient.
