Abstract: | The contents of three major steviol glycosides (SGs) (stevioside and rebaudiosides A and C) in vegetative and generative organs during ontogeny of Stevia rebaudiana Bertoni were analysed with HPLC. Plant organs contained different amounts of the SGs, which declined in the following order: leaves, flowers, stems, seeds, roots. The highest content of the SGs was found in upper young actively growing shoot sections, whereas lower senescent shoot sections exhibited the lowest amount of such compounds. During ontogeny a gradual increase in the SG content was observed in both mature stevia leaves and stems, and this process lasted up to the budding phase and the onset of flowering. This revised version was published online in July 2006 with corrections to the Cover Date. |
