Název v původním jazyce

Changes in endogenous cytokinins during germination and seedling establishment of Tagetes minuta L.

Popis výsledku v původním jazyce

Endogenous cytokinins were quantified and identified in germinating achenes and developing seedlings of Tagetes minuta L. incubated at 25 degrees C over a 144 h period. The process of germination (radicle emergence) was completed 38 h after commencementof imbibition. Subsequent growth was considered to cover seedling establishment. Eighteen isoprenoid cytokinins, belonging to the zeatin (9), dihyrozeatin (5) and isopentenyladenine (4) groups and one aromatic cytokinin, benzyladenine, were identified. The total isoprenoid cytokinin concentration increased upon imbibition, reached a peak by 48 h and subsequently decreased with seedling development. The individual cytokinin groups and the respective derivatives within each group did, however, not followsuch a consistent trend. During the course of the experiment, the ribotides and ribosides were present in the highest concentrations, reaching a peak at 48 h and decreasing thereafter. The free bases and O-glucoside remained at low levels
