e1“Grain from barley (Hordeum vulgare L. cv ;Onda'; containing 40 to 80 nanograms of Ni per gram dry weight) grown in solution culture with negligible Ni concentrations (< 30 nanograms of Ni per liter) exhibited greatly reduced germination rates (i.e. 50% less than grain from Ni-adequate plants)”

Other claims from this paper (8)
- Observation Barley grain containing less than 30 nanograms of Ni per gram dry weight was inviable.
- Observation Seedling vigor of viable barley grain from nickel-deficient plants was greatly depressed.
- Mechanism Under nickel-deficient conditions, barley plants failed to produce viable grain because of a disruption of normal grain-filling and maturation processes after grain embryo formation.
- Association Barley plants failed to complete their life cycle in the absence of Ni.
- Association Adding Ni to the growth medium completely alleviated deficiency symptoms in the maternal barley plants.
- Recommendation Nickel should be considered a micronutrient for cereals.
- Recommendation Nickel should be added to the list of micronutrients essential for all higher plant growth.
- Observation Barley observations on life-cycle completion and maternal-plant symptom alleviation satisfy the essentiality criteria for nickel.
