Field trials conducted in Orkney (calcareous sandy soil, pH 7.8) or mainland Dundee (Mn-replete site). (A) Visual appearance of the Bere barley landrace (Bere North Ronaldsay, left plot) and the modern elite genotype (KWS Irina, right plot) growing in Orkney. (B) Severe Mn deficiency symptoms of interveinal chlorosis (younger leaves) and necrotic aligned interveinal spots (older leaves) in the modern elite genotype KWS Irina (left photo), together with wind-damaged leaves (centre photo). An unaffected leaf of Bere Unst Shetland is shown to the right. (C) PSII efficiency (Fv/Fm) of the youngest fully developed leaves of Orkney-grown plants. Values are means ± s.e. (n = 4). Bars with the same letter are not significantly different (P ≥ 0.05). (D) Grain yields obtained in the Dundee (black bars) and Orkney (red bars) field sites. The values are means ± s.e (n = 3–4).
