Effect of Uniconazole and Gibberellin on the Flowering of Pharbitis nil
スポンサーリンク
概要
- 論文の詳細を見る
The role of endogenous gibberellin (GA) in the flowering of the short-day plant, Pharbitis nil, was investigated by using uniconazole, which is a specific inhibitor of GA biosynthesis. Both the endogenous GA level and flowering response decreased with increasing concentration of uniconazole applied via the roots. The strongest inhibition of flowering was observed when uniconazole was applied one day before a 15-h dark treatment. The inhibition by uniconazole was overcome by an application of GAs to the plumules, the order of effectiveness of the endogenous GAs in P. nil being GA_1≧GA_<20>>GA_<19>≧GA_<44>>GA_<53>≫GA_8. This is the first report of the correlation between the endogenous GA level and flowering response in P. nil. It was found that endogenous GAs were required for the flowering of P. nil during or just after the dark period.
