title: [Influence of α-methyl-DL-tryptophan on anthocyanin synthesis in seedlings of Sinapis alba L].
abstract: α-methyl-DL-tryptophan stimulates anthocyanin synthesis in dark grown seedlings of Sinapis alba L. Effective concentrations are between 10(-4) m and 10(-3)m. This stimulation is accompanied by an inhibition of root and shoot growth.The induction of anthocyanin synthesis by red light (3×10(3) erg cm(-2) sec(-1)) is complete after an exposure time of 3 minutes regardless of whether or not the plants were treated with α-methyl-DL-tryptophan.Isonicotinic acid hydrazide inhibits growth of Sinapis alba in a similar manner. It does not affect anthocyanin synthesis.
