Abstract:
Wheat samples of twelve varieties, grown by breeders at NIAB, Faisalabad Pakistan and its soil, were collected and analyzed for aluminum and barium content by atomic absorption spectroscopy using acetylenenitroxide flame. For dissolution of heavy metals, aluminum and barium, wet acid digestion method was used. The experimental study was conducted using six samples for each twelve wheat varieties of FSC&RD (Federal seed certification and registration department) as standard reference materials and representative samples, and the soil, which was also collected from agricultural plot of Nuclear Institute of Agriculture & Biology (NIAB), Faisalabad, Punjab. The characteristics mean of both elements in each variety of representative samples was found to be 28.32, 71.02, 37.41, 36.95, 28.32, 47.40, 30.14, 14.69, 25.41, 32.86, 30.14, and 41.95 for. the aluminum and 12.67, 6.92, 5.67, 19.82, 3.28, 17.34, 10.25, 10.49, 8.01, 14.23, 15.16 and 6.92 mg/kg for the barium of Chakwal-86, Bakhatawar-92, Shahkar-95, Parwaz-94, Punjab-96, Bahawal pur-97, Shahkar-91, Inquilab 91, Pasban-90, Punjab-85, Faisalabad-85 and Pak-81 varieties respectively. The soil of that specific plot contains 35964.3 and 111.08 mg/kg of aluminum and barium respectively. The representative samples, which were compared with certified samples at 95% confidence limit. The purpose of this study was to study the variation in uptake of aluminum and barium in twelve different wheat varieties grown in same agricultural plot.
