Summary

Nickel (Ni) is essential for cereal crops like barley, impacting grain viability and seedling vigor. Its deficiency disrupts grain development, confirming Ni as a vital micronutrient for all higher plants.

Area of Science:

  • Agricultural Science
  • Plant Physiology
  • Nutrient Management

Background:

  • Nickel (Ni) is a known essential micronutrient for legumes.
  • Its role in cereal crops, particularly temperate cereals like barley, was not fully established.
  • Understanding Ni's function is crucial for optimizing crop yield and plant health.

Purpose of the Study:

  • To investigate the essentiality of nickel (Ni) for the growth and reproductive success of temperate cereal crops.
  • To determine the effects of Ni deficiency on barley (Hordeum vulgare L.) grain development and germination.
  • To establish Ni as a required micronutrient for cereals.

Main Methods:

  • Barley plants (cv. 'Onda') were grown in solution culture with controlled, negligible Ni concentrations.

  • Grain Ni content was analyzed, correlating with germination rates and seedling vigor.
  • Plant life cycle completion and deficiency symptom alleviation with Ni addition were observed.

    • Main Results:

    • Barley grain with Ni levels below 30 ng/g dry weight was inviable.
    • Ni-deficient grain (40-80 ng/g dry weight) showed significantly reduced germination rates (50% less) and seedling vigor.
    • Ni deficiency disrupted maternal plant processes essential for grain filling and maturation.

    Conclusions:

    • Nickel (Ni) is an essential micronutrient for temperate cereal crops, including barley.
    • Barley plants cannot complete their life cycle without adequate Ni supply.
    • Ni's established essentiality for both legumes and cereals supports its inclusion as a universal micronutrient for higher plant growth.
