Lowland rice is a staple food for more than 50% world population. Iron toxicity is one of the main nutritional disorders, which limits yield of lowland rice in various parts of the world. The toxicity of iron is associated with reduced soil condition of submerged or flooded soils, which increases concentration and uptake of iron (Fe2+). Higher concentration of Fe2+ in the rhizosphere also has antagonistic effects on the uptake of many essential nutrients and consequently yields reduction. In addition to reduced condition, increase in concentration of Fe2+ in submerged soils of lowland rice is associated with iron content of parent material, oxidation-reduction potential, soil pH, ionic concentration, fertility level, and lowland rice genotypes. Oxidationreduction potential of highly reduced soil is in the range of ?100 to ?300 mV. Iron toxicity has been observed in flooded soils with a pH below 5.8 when aerobic and pH below 6.5 when anaerobic. Visual toxicity symptoms on plants, soil and plant tissue test are major diagnostic techniques for identifying iron toxicity. Appropriate management practices like liming acid soils, improving soil fertility, soil drainage at certain growth stage of crop, use of manganese as antagonistic element in the uptake of Fe2+ and planting Fe2+ resistant rice cultivars can reduce problem of iron toxicity. |

The objective of this study was to evaluate the physico-chemical characteristics of fruits of 58 sweet orange tops cultivars on four rootstocks, namely: 'Sunki Tropical' mandarin and ?'rifoliata' Citrandarin 'San Diego', 'Riverside' and 'Indio'. For this purpose, a completely randomized experimental design was used, in a factorial scheme (58 x 4). The characteristics analyzed were: equatorial diameter, fruit mass, peel thickness, number of seeds, soluble solids, titratable acidity, Ratio and juice yield. All the characteristics analyzed were influenced by both the tops cultivar and the rootstock, demonstrating that both factors interfere in the physicochemical quality of the fruits. The tops 'Pera D-3', 'Pera Olimpia', 'Pera Bianchi', 'Jaffa' and 'Westin' on all rootstocks evaluated showed characteristics in their fruits with soluble solids greater than 10 ºBrix, Ratio above 9.5 and juice yield greater than 45%, characteristics that define fruits with quality standards. Also, the tops 'Pera Olimpia', 'Sincorá' and 'Westin' on the rootstock 'Sunki Tropical', 'Pera D-3', 'Pera D-25', 'Sincorá', 'Aquiri' and 'Russas P.S.' on the rootstock 'San Diego', 'Pera C-32', 'Pera D-3', 'Pera D-6', 'Pera E-6', 'Pera Bianchi', 'Pera CE-03', 'Salustiana' and 'Westin' on 'Riverside' rootstock are suitable for the juice production industry with Ratio between 14 and 16 and juice yield greater than 50%. It is also worth noting that the tops 'Crescent', 'Natal Folha Murcha', 'Valencia Midknight' and 'Valencia Delta' produced fruits without seeds on all rootstocks.
