We investigated the uptake and distribution of zinc (Zn) either applied to the roots or to the leaves in rice during grain development. Plants of two aerobic rice cultivars were grown in a nutrient solution with either sufficient Zn or surplus Zn. Root treatment with 1 week's supply of both 65 Zn and unlabelled Zn was started at flowering or 15 days after flowering (DAF). Foliar treatment with 65 Zn applied to the flag leaf or to senescent leaves was carried out at flowering. When 65 Zn was applied to roots, plants continued to take up Zn after flowering, even beyond 15 DAF, irrespective of cultivar and Zn nutritional status of the plants. During the 1 week of supply of both 65 Zn and unlabelled Zn, which either started at flowering or 15 DAF, the absorbed 65 Zn was mainly distributed to roots, stem and grains. Little 65 Zn was allocated to the leaves. Following a week of 65 Zn supply directly after flowering, under sufficient Zn or surplus Zn, the proportions of total 65 Zn uptake allocated to the grains continued to change during grain filling (9-33%). This Zn mainly came from the roots but under sufficient Zn supply also from the stem. With 65 Zn applied to leaves (either the flag leaf or the lowest senescent leaf), both cultivars showed similar Zn distribution within the plants. About 45-50% of the 65 Zn absorbed was transported out of the 65 Zn-treated leaf. From that Zn, more than 90% was translocated to other vegetative organs; little was partitioned to the panicle parts and even less to the grains. These results suggest that in rice plants grown under sufficient or surplus Zn supply, most of the Zn accumulated in the grains originates from uptake by roots after flowering and not from Zn remobilisation from leaves.

“…Zn accumulated in grains mainly originates from Zn uptake by roots after flowering, as shown in paddy rice (Verma & Tripathi, 1983), cotton (Constable et al , 1988) and sorghum (Traoré, 2006). Therefore, enhanced Zn supply to the root environment during grain filling (e.g.…”

“…Iron applied separately increased yield, and a high amount gave a higher yield. Partially, similar results were reported by Verma and Tripathi [67], who illustrated the decrease of grain and straw yield in the paddy; when Zn was not applied, Fe application decreased grain yield and straw, but with an addition of Zn, Fe did not affect grain and straw. The present study showed that low a percentage of Fe in the solution reduced the yield, while higher percentages increased the yield.…”

Winter Wheat Grain Quality, Zinc and Iron Concentration Affected by a Combined Foliar Spray of Zinc and Iron Fertilizers

et al. 2019

Wheat (Triticum aestivum L.) is one of the main foods globally. Nutrition problems associated with Zinc and Iron deficiency affect more than two billion individuals. Biofortification is a strategy believed to be sustainable, economical and easily implemented. This study evaluated the effect of combined Zn and Fe applied as foliar fertilizer to winter wheat on grain yield, quality, Zn and Fe concentration in the grains. Results showed that treatments containing high Fe increased the yield. Grain crude fat content remained unaffected. Crude fiber was enhanced up to three-fold by 60% Zn + 40% Fe5.5 (5.5 kg ha−1 of 60% Zn + 40% Fe). Moreover, 80% Zn + 20% Fe5.5 (5.5 kg ha−1 of 80% Zn + 20% Fe) was the best combination for increasing crude protein. Zinc applied alone enhanced Zn concentration in grain. In addition, Fe was slightly improved by an application of Zn and Fe in the first year, but a greater increase was observed in the second year, where 100% Fe13 (13 kg ha−1 of 100% Fe) was the best in improving Fe in grain. Foliar application of Zn and Fe is a practical approach to increase Zn and Fe concentration, and to improve the quality of wheat grains.
