“…The current findings agreed with results conducted in West Asia (24,32,33) and are consistent with previous results indicating that Fe can move from leaf to grain (28,31,44) but are inconsistent with results found in Canada (34). It is notable that the effects of foliar Fe application on grain Fe concentration depended on climate, soil condition, and timing of application.…”

Human deficiencies of iron (Fe) and zinc (Zn) are worldwide problems. Biofortification of wheat could reduce Fe and Zn deficiencies in societies that depend on wheat consumption. This study investigated the effects of foliar application of Fe with or without Zn on the concentrations of Fe and Zn in grain and especially in flour of three wheat cultivars. On average, grain Fe concentration was increased significantly from 29.5 mg kg(-1) in the control to 37.8, 35.9, or 34.9 mg kg(-1) by application of FeSO4, ferric citrate plus ZnSO4, or ferric citrate, respectively. As expected, grain Zn concentration was increased from 29.0 mg kg(-1) in the control to 45.7 or 39.6 mg kg(-1) by application of ferric citrate plus ZnSO4 or a complex of micronutrients. Although the Fe and Zn concentrations in flour were inherently lower than in bran and shorts made by experimental mill, the concentrations in flour were simultaneously increased from 10.4 to 12.4 mg kg(-1) for Fe and from 11.8 to 17.4 mg kg(-1) for Zn by application of ferric citrate plus ZnSO4. Importantly, Fe was peripherally localized within grain fractions and strictly limited to transport to endosperm, making it more difficult to increase the quantity of Fe in flour products by foliar Fe application, but the situation with Zn is promising because Zn is more readily transported to the endosperm than Fe. The current study increases the understanding of agronomic biofortification.

“…The concentration of Zn in cereal grains is generally low and the bioavailability is also reduced due to the existence of anti-nutrition factors such as phytic acid. Increasing Zn concentration of cereal grains has been identified as a way of addressing human Zn deficiency (Garnett and Graham, 2005;Muminjanov et al, 2007;Pahlavan-Rad and Pessarakli, 2009).…”

To increase grain Zn concentration of wheat grown on calcareous soil, field and hydroponic culture experiments were conducted to investigate the effects of various Zn fertilization methods on Zn absorption and translocation in wheat. A completely randomized block design was used in the field experiment comprising five Zn treatments (0, 7.5, 15, 30, and experiment used a completely randomized block design with two factors (Zn supplementation to root and foliar spray of Zn). Results showed that in the field experiment, Zn fertilization significantly increased the amount of soil diethylene triamine penlaacetic acid-Zn (DTPA-Zn), whereas there was no significant effect on Zn concentration in grain. Furthermore, the utilization rate of Zn fertilizer was only 0.98%, 0.64%, 0.29%, and 0.14% with treatments of 7.5, 15, 30, and 45 mg Zn ha -1 , respectively. In contrast, the hydroponic experiment showed that both foliar spray and Zn supplied to roots significantly increased Zn concentration in grain, with the greatest concentration found in shoots. Results suggested that lower absorption and translocation were the inhibitory factors to increase grain Zn concentration in calcareous soil. Consequently, Zn fertilization to potentially Zn-deficient calcareous soils is not effective method to increase grain Zn concentration.

“…It is, therefore, essential to understand the molecular mechanism through which plants take up, mobilize, translocate and store Zn in the edible plant parts (Ishimaru et al 2011). As genotypic variation for grain Zn and Fe concentration is relatively narrow and limited among different cereal crops, soil and foliar application of Zn is commonly practiced to augment Zn concentration in grains (Cakmak 2002, Pahlavan-Rad andPessarakli 2009). In the present study, an attempt has been made to evaluate the translocation and enrichment of 65 Zn in two contrast rice varieties which varied in their Zn tolerance under different methods of zinc fertilizer application.…”

Zinc (Zn) is an essential micronutrient for growth and development of almost all organisms and its deficiency severely affects the health of plants, animals and humans. In order to investigate the enrichment of Zn in cereals a pot experiment was performed in two contrasting rice varieties viz., PD16 (zinc efficient) and NDR359 (zinc inefficient) under different levels of zinc regimes such as control (0 Zn), soil application (5 mg Zn/kg soil tagged with 3.7 MBq of 65 Zn/pot), foliar spray of 0.5% ZnSO 4 at 30, 60 and 90 days (925 KBq of 65 Zn/pot), soil application (5 mg Zn/kg soil tagged with 3.7 MBq of 65 Zn/pot) + foliar spray of 0.5% ZnSO 4 at 30, 60 and 90 days (925 KBq of 65 Zn/pot). Both varieties markedly differ in 65 Zn accumulation and grain Zn content. NDR359 showed poor translocation efficiency and accumulated relatively less 65 Zn in all the plant parts. In both rice varieties, highest concentration of Zn in dehusked grains could be obtained with soil application of Zn + foliar spray of zinc sulphate. Though NDR359, a zinc inefficient variety exhibited poor zinc translocation efficiency yet, it contained more Zn content in grains with husk and dehusked grains than PD16.
