| Outline of Final Research Achievements |
In this study, to verify the biosynthesis pathway and physiological role of auxin in the flowering of gladiolus, exogenous application of novel auxin-biosynthesis inhibitors were examined.
The result revealed that indole-3-pyruvic acid pathway has been suggested as a major biosynthesis pathway in the flowering of gladiolus floret. Application of the auxin-biosynthesis inhibitors showed reduced endogenous indole-3-acetic acid (IAA) content and ethylene production in flowering of gladiolus floret. These results suggested that reduced IAA content may suppress growth and hypertrophy, and reduced ethylene production may suppress aging in the floret of gladiolus.
