Conteúdo: | Development of cultivars of flooded rice, which are tolerant of iron toxicity is an important step in reducing production costs and increasing rice yields in many parts of the world. Success has been limited by inadequate screening techniques and the lack of sufficient data showing c1ear differences in response to well defined iron stress. Twelve ftooded rice (Oryza sativa L.) cultivars were evaluated over three iron concentrations (90, 890, and 1780 u.M Fe) in nutrient solution. Based on shoot dry weight, cultivars were c1assified relative to tolerance of iron toxicity. Rice cultivars differ in their response to iron toxicity. The tolerant cultivars at the highest Fe concentration were P3083F4-61, CNA 1051, CNA 3814, and P3304F4-27. High Fe concentration in the growth medium reduced uptake of P, K, Zn and Mn.
