Abstract

The change of amino acids was analysed with cotyledons and roots of young spring radish by the treatment of <TEX>$Cd^{2+}$</TEX> ion and <TEX>$Cd^{2+}$</TEX> ion plus PA. The concentration of Asp was decreased by the treatment of <TEX>$Cd^{2+}$</TEX> ion, but Ala, Phe, Val, Ile, Typ, Lys and Arg was increased in the cotyledons. The concentration of Lys and Arg was decreased by the treatment of <TEX>$Cd^{2+}$</TEX> ion plus PA at the same time. The concentration of basic amino acids, His, Lys and Arg was increased by the treatment of <TEX>$Cd^{2+}$</TEX> ion, and decreased by the treatment of <TEX>$Cd^{2+}$</TEX> ion and <TEX>$Cd^{2+}$</TEX> ion plus PA in the roots. Only the concentration of Pro was increased by the treatment of <TEX>$Cd^{2+}$</TEX> ion plus PA. This results showed that Pro was induced against stress of PA, and assumed that the change of other amino acids concentration may be relation to the metabolism against stress.
