“…Al resistance in IRAT and IR was also associated to a restriction of Al translocation from root to shoot as shown by Al shoot/root ratio (Table 1). Similar findings were already reported for rice (Fageria & Carvalho, 1982;Jan & Pettersson, 1989) and maize (Guevara et al, 1992). The results of this research suggest that in rice, Al exclusion and internal mechanisms of detoxification could exist simultaneously to avoid and/or to tolerate Al at root level.…”

The effects of aluminum (Al) stress on ion concentration and distribution were investigated in four rice cultivars (Aiwu and IKP, Al sensitive; IRAT112 and IR6023, Al resistant). Macro and micronutrient levels in plant tissues were markedly affected by Al and the magnitude of this effect depended on the cultivar group (Al resistance versus Al sensitivity) and on the concentration of Al in the nutrient solution. Al decreased Ca, P, K, Mg and Mn concentrations in shoot and K, Mg and Mn in root. It increased Ca and P in root and caused an increase in shoot and root Al contents. All these effects were observed in both cultivar groups, but were more apparent in Al sensitive ones. In conclusion, the results support the idea that, compared to the Al sensitive cultivars Aiwu and IKP, Al resistance in IRAT112 and IR6023 could be explained by a limited absorption and translocation of Al from root to shoot and could also be explained by a more efficient transport of Ca, P and Mn from root to shoot. These findings showed clearly that more than one mechanism may contribute to Al resistance in rice plants.

A presença do Al diminuiu a concentração de Ca, P, K, Mg e Mn nas folhas, mas a aumentou em K, Mg e Mn nas raízes. O Al causou aumento da concentração de Ca e P nas raízes e aumentou a sua quantidade nas folhas e raízes; esses efeitos foram observados nos dois grupos das cultivares, embora de forma mais marcada nas cultivares sensíveis ao Al. Os resultados reforçam a idéia de que, comparativamente às cultivares sensíveis Aiwu e IKP, a resistência ao Al nas cultivares resistentes IRAT112 e IR6023, pode ser explicada por uma absorção limitada e translocação do Al das raízes para as folhas e, possivelmente, por um transporte mais eficiente de Ca, P e Mn das raízes para as folhas. Os resultados mostram que mais de um mecanismo pode contribuir para a resistência ao Al, em plantas de arroz.Palavras-chave: mecanismo de resistência, alocação de nutrientes, oryza sativa

“…In some instances, liming even the surface soil may not be feasible because soils must be kept acidic (below pH 5.4) for disease control, or because lime is unavailable or prohibitively expensive (Foy, 1988). In all of these situations, Al-tolerant plants offer an alternative or supplemental solution to the problem (Foy, 1983;Furlani, 1987;Jan & Pettersson, 1989;Little, 1988). Bouton et al (1986) determined that acid subsoils can reduce yields substantially in alfalfa; but that subsoil liming, gypsum application or, possibly, tolerant cultivars can be helpful in overcoming the problem.…”

Diallel analysis of tolerance to aluminium in alfalfa

Acid soils having high levels of aluminium (A1) can drastically reduce yields in alfalfa and the most economically viable solution to the problem appears to be the development of Al-tolerant cultivars. To assist with the choice of a breeding method, a six-parent alfalfa diallel (crosses and reciprocals included but not parents) was evaluated in Al-toxic nutrient solution in terms of height (HT) and dry weight (DW). General combining ability was significant for both traits and constituted the majority of the genetic variation. Specific combining ability was significant only for HT and reciprocal effects were significant only for DW. Tolerance appeared to be at least partially dominant to sensitivity. Results indicate that a mass selection scheme, such as recurrent phenotypic selection, may be effective in increasing levels of tolerance in at least some alfalfa populations and that minor grains may also be achieved through exploiting non-additive genetic variation.
