Recent research has shown the need for an in-depth knowledge of zinc
biofortification of cereal and oilseed grains due to its importance to human
nutrition. However, little is known about the Zn dynamics in plant?soil system.
In this work, we evaluated the effect of soil-applied Zn on the absorption,
translocation, and compartmentalization of Zn in rice (Oryza sativa L.)
and soybean (Glycine max L. Merrill) plants. The soil used in the greenhouse
experiment was fertilized with zinc chloride (ZnCl2) at rates of 0, 1,
2, 4, and 8mg Zn kg1. The source of Zn was labeled by 65Zn with specific
activity of 185.5 kBq mg1 Zn. The amount of Zn derived from fertilizer
and its use in each plants compartment was determined by direct method
in isotopic calculations. Rice and soybean plants presented low efficiency
in the absorption from soil-applied Zn. The accumulated Zn in the panicle,
pod, and grains was not modified, due to its low translocation in the plant.
The Zn uptake in rice plants was from 1.34 to 4.60mg pot1 in shoots and
just 0.81 to 1.43mg pot1 translocated to panicles. Soybean plants presented
Zn uptake between 2.36 and 4.68mg pot1 in shoots, out of which
0.19 to 0.34mg.pot1 and 0.48 to 0.57mg pot1 translocated to grains
and pods, respectively. The nutrient utilization from fertilizer was low, with
mean values of 12 and 8.7% for rice and soybean plants, respectively. Soilapplied
Zn showed low capacity for enriching rice panicle and soybean
pod or grain probably due low Zn uptake and translocation. MenosRecent research has shown the need for an in-depth knowledge of zinc
