Elemental analysis of hydroponically-grown wheat shoot tissue
| Element | Hydroponics | Reference valuea |
|---|---|---|
| Al (mg kg−1) | 2.4 ± 0.5 | < 200 |
| B (mg kg−1) | 4.4 ± 1.1 | 3–25 |
| Ca (% w w−1) | 0.20 ± 0.01 | 0.18–0.40 |
| Cu (mg kg−1) | 17.7 ± 0.5 | 1.3–18.0 |
| Fe (mg kg−1) | 63 ± 2 | 25–100 |
| K (% w w−1) | 3.2 ± 0.1 | 3.0–3.5 |
| Mg (% w w−1) | 0.08 ± 0.003 | 0.05–0.40 |
| Mn (mg kg−1) | 93 ± 6 | < 700 |
| P (% w w−1) | 0.21 ± 0.02 | 0.24–0.70 |
| S (% w w−1) | 0.35 ± 0.01 | 0.28–0.30 |
| Zn (mg kg−1) | 102 ± 4 | 18–390 |
Whole-shoot tissues of sterile hydroponically grown 30-day-old wheat plants were homogenised and elemental content analysed by ICP-MS. Results show the mean ± SE (n = 10 plants)
aReference values were based on the values (wheat at the Feekes scale 3 growth stage) previously reported [68]
