Abstract
Summaryα-methyl-Dl-tryptophan stimulates anthocyanin synthesis in dark grown seedlings of Sinapis alba L. Effective concentrations are between 10-4 m and 10-3m. This stimulation is accompanied by an inhibition of root and shoot growth.The induction of anthocyanin synthesis by red light (3×103 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.
