EFECTO TÓXICO DEL IÓN AL3+ EN EL ÁPICE RADICULAR DE DOS CULTIVARES CUBANOS DE ARROZ (Oryza sativa L.)

Aluminium toxicity is an important factor limiting crop productivity in acid soils and toxic effects of this metal are primarily root related. The aim of this paper was to study responses to Al toxicity in two Cuban rice cultivars and the relation with Al localization at root of seedlings. Different AlCl3 levels were employed to impose stress condition.
