Abstract: | Two Al-tolerant genotypes (KB 44001 and Genjah Jepang;) and two Al-sensitive genotypes of soybean (Kedelai Lumut and KB 46015) were subjected to A1 concentration (1.50 mM A1 with pH 4.0) in hydroculture for 3 weeks; the growth and their physiological responses were ident$ed by measuring the changes ofpH media, NO~-/NHu~p+ta ke, ion absorption and organic acid content in the tissues. The results revealed that Al-tolerant genotypes soybean show a much better growth than the sensitive genotypes. Moreover, the tolerant genotypes showed the different responses to A1 stress; they changed the pH media more signz$cantly, accumulated less A1 in the roots and accumulated more oxalate acid than the sensitive genotypes. Both the tolerant and sensitive genotypes had similar pattern in NO~-/NHu~p+ta ke and other cation uptake. The results suggested that tolerance ofsoybean genotypes to A1 toxicity is associated with their ability in the exclusion gf Al. |
