Physico-chemical properties of starches isolated from potato cultivars grown in soils with different phosphorus availability.
BACKGROUND Starch is the major component of potato tubers, amounting approximately to 150-200 g kg (-1) of the tuber weight. Starch is considered to be a major factor for the functionality of the potato in food applications. This study evaluated the physical characteristics of potato starches isolated from tubers of different potato cultivars grown in soil with three levels of phosphorus (P) av...

متن کاملRice Uptake and Leaching of Tc in Different Paddy Soils Contaminated According to Two Contrasting Scenarios
Four different paddy soils collected around the Gyeongju nuclear site were treated with TcO4 solution under the assumption of two contrasting contamination scenarios. Scenario I (SN-I) is for a pre-transplanting deposition of Tc followed by plowing, whereas SN-II is for its deposition onto the water surface shortly after transplanting. Rice plants were grown in lysimeters in a greenhouse. Plant...

15 صفحه اولTc in Paddy Soils Contaminated in Two Different Ways
Rice is one of the most important food crops in the world. All isotopes of technetium (Tc) are radioactive, and the environmentally most important one is 99 Tc because of its very long half-life (2.1x10 5 years) and relatively high 235 U-fission yield [1,2]. Accordingly, it is one of the critical radionuclides in an environmental impact assessment for radioactive waste disposal. A significant a...
