Promotion of Flowering in Sagittaria pygmaea Miq. by 2,6-Diisopropylphenoxyacetic Acid.
The flowering of Sagittaria pygmaea Miq. was promoted by 2,6-diisopropylphenoxyacetic acid, as well as by gibberellic acid (GA3). Uniconazole canceled the promotive effect of the phenoxy-acetic acid, while prohexadione shortened the period required for flowering. Endogenous GAs seem to play an important role in the flowering of S. pygmaea, and 2,6-diisopropylphenoxyacetic acid might affect GA biosynthesis or metabolism.
