title: Effects of Plant Growth Regulators on Shoot Growth and Flowering of a Perennia Paddy Weed, Sagittaria pygmaea Miq.
abstract: Plant growth regulators (PGRs) including gibberellins (GAs) were examined for their effects on shoot growth and flowering of a perennial paddy weed, Sagittaria pygmaea Miq. Among PGRs tested, only GAs (A1 A3, A4, and A5), AC-94377 [1-(4-chloro-1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)cyclohexanecarbox-amide] and 2,6-diisopropylphenoxyacetic acid (DIPA) promoted both shoot growth and flowering. Structural requirements of GAs for promotion of flowering seemed to be different from those for shoot growth of the weed. In addition, since the course of flowering induced by DIPA was clearly different from that observed in plots treated with GA3 or AC-94377, different mechanisms may be involved in promotion of flowering.
