摘要 The primary objective to these study was to test NPKCaMg-fertilization induced "Zn(2+)" bioavailability in triticale rhizosphere soils. Soil and plant samples were taken from experimental sites randomly, and were analysed in laboratory to plant available Zn^2+) content. Zinc "Zn(2+)" concentrations showed a large variability to interactions with soil's pH values. It ranged from 0.4 and 1.36 mg kg1. Soil's "Zn(2+)" contents had been significantly lower than International Soil Limit (ISL) value (70 mg kgl), consequently. Plant available "Zn(2+)" contents from triticale rhizosphere soils in Leaf+Straw ranged from 10.1 to 38.4 mg kgl, and in Seed from 26.9 to 52.0 mg kg1. "Zn(2+)"s Actual Translocation Index (ATI) from rhizosphere soils to Leaf+Straw had as average 23.6, and to grain 43. 1. "Zn(2+)" Leaf+Straw bioacummulation (g hal) had as average 13.4, Grain 23.2, and total (Leaf+Straw+Grain) 36.6. "Zn(2+)"translocation from soils to Leaf+Straw was 37% lower than to Grain. Ultimately, within the range of experimental conditions tested these results are present that "Zn(2+)" tends to accumulate to triticale organs to create the conditions for toxicity effects in Food Chane.
