Summary
The importance of seed manganese (Mn) content for seedling growth of two wheat cultivars under soil Mn deficiency was demonstrated in growth cabinet experiments. Seed was obtained from different field sites (giving a Mn content range of 0.1 to 6.4 μg Mn seed−1), as well as from soaking seed in MnSO4 prior to sowing. Seed soaking greatly increased the seed Mn content, however, only about 15–20% of this additional Mn was recovered in the seedlings after 26 days growth. In these experiments, the seed rather than the soil provided the major source of plant Mn. Manganese critical deficiency levels (CDLs) were also obtained for leaves, shoots and roots. Increased grain yields from seed soaking were also evident in the field.
