Abstract
The content of endogenous GA4 and GA7 was determined in apple embryos cultured either on water or in the presence of ABA solution. The embryos were isolated from dormant seeds and from seeds removed from stratification which was effected either in water or in the presence of ABA. The influence of ABA on the decrease of two GAs levels was proved. The relation between the effect of ABA and the stage of stratification is closer in the case of GA4 than GA7. It is assumed ABA to inhibit the gibberellin biosynthesis. Autoři sledovali obsah endogenních giberelinů GA4 a GA7 v embryích jabloně pěstovaných ve vodě nebo v roztoku abscisové kyseliny (ABA). Embrya pocházela ze semen odpočívajících nebo ze semen stratifikovaných ve vodě nebo v roztoku ABA. Bylo zjištěno, že ABA vyvolává snížení obsahu giberelinů. Závislost mezi vlivem ABA a stadiem stratifikace bylo u GA4 výraznější než u GA7. Autoři předpokládají, že ABA inhibuje biosynthesu giberelinů.Keywords
