Effect of Actinomycin D and 2-Thiouracil on Floral Induction and Nucleic Acid Synthesis in the Bud in Chenopodium Amaranticolor

Actinomycin D and 2-thiouracil inhibit floral initiation in C. amaranticolor when applied to plants before the end of the inductive dark period. Actinomycin D does not suppress floral differentiation if it is applied to plants more than 48 hr after the inductive dark cycle, whereas 2-thiouracil retains its ability to interfere with floral differentiation when applied to plants several days after the inductive dark period.
