PRELIMINARY STUDIES ON THE EFFECT OF GIBBERELLIC ACID ON DILL SEED
Publication History
Publication Date:
15 January 2009 (online)
Summary
GA was applied in different concentration to the seedlings of Anethum sp. at preflowering stage. It produced the usual gibberellin effects: early flowering, longer and thicker stems. In specific doses the increase of the oil in the seed was upto 50 per cent in A. graveolens and on an average upto 30 per cent in A. sowa. There was no significant increase in the Carvone content of A. graveolens in lower concentrations but in higher concentrations there seemed to be a slight increase in the carvone from the B. P. limits. Possibilities for the increase in the oil yield are also indicated.
Zusammenfassung
Junge Pflanzen von Anethum graveolens und A. sowa wurden mit Gibberellinsäure in Konzentrationen von 25 bis 400 ppm behandelt. Neben den bekannten morphologischen Wirkungen trat bei bestimmten Konzentrationen eine Erhöhung des ölgehaltes in den Früchten um 30–50 % auf. Der Garvon–Anteil wird dabei nur wenig verändert.
