The changes of ABA level in the root-xylem sap and plants of winter barley cv. Lunet treated by low temperature

Popis výsledku v původním jazyce

Transport and changes of abscisic acid (ABA) were studied in plants of winter baley cv. Lunet treated by low temperature. (LT). Fluridone was used for ABA synthesis inhibition. Endogenous levels of ABA increased in the aboveground parts already 3 h after treatment by LT. The aboveground parts treated by fluridone had higher level of ABA 3 h after ABA treatment and after 1 d the ABA level decreased. The ABA level was increased in roots of plants treated with fluridone or LT. Combination of fluridone and LT resulted in lowering of ABA level in the roots. Fluridone treatment did not reduce the ABA level in root-xylem exudate. LT treatment increased mildly the ABA level in this exudate. The uptake of 14C-ABA was lowest after LT treatment. Application offluridone at +20 C resulted in the change of 14C-activity distribution in plants.
