| Description
| - The study presents the comparative analyses of endogenous contents of auxin (IAA), cytokinins (CKs), polyamines (PAs), and phenolic acids (PhAs) in apical and basal parts of elm multiplicated shoots with regard to the organogenic potential. The shoot-forming capacity was higher in the apical part than in the basal part. However, the timing of root formation was in the apical type of explant significantly delayed (compared with the organogenic potential of basal part). Significantly higher contents of free bases, ribosides and ribotides of isopentenyl adenine, zeatin and dihydrozeatin that were found in the apical segments, might be considered as the most important factor affecting in vitro shoot formation. The content of endogenous free IAA was approximately three times higher in the basal shoot parts than in the apical parts. The amounts of putrescine and spermidine were higher in the apical part which generally contains less differentiated tissues than the basal part of shoot. The predominant PhA...

- V apikálních a basálních segmentech multiplikovaných prýtů jilmu byly stanoveny endogenní obsahy IAA, cytokininů, polyaminů a fenolických kyselin. Apikální segmenty vytvářely vyšší počet adventivních stonků, ale později zakořeňovaly (ve srovnání s basálními segmenty). Významně vyšší obsah volných basí, ribosidů a ribotidů isopentenyladeninu, zeatinu a dihydrozeatinu a vyšší množství putrescinu a spermidinu v apikálních segmentech pravděpodobně ovlivnilo in vitro tvorbu stonků. V basálních segmentech bylo stanoveno trojnásobné množství IAA (ve srovnání s apikálními segmenty) a vyšší obsah fenolických kyselin – prekursorů pro biosyntézu ligninu. (cs)
