[The effect of low temperature, nitrogen atmosphere and uncouplers on longitudinal distribution of radioactivity after acropetal and basipetal application of [2-(14)C] ABA in long root segments of Phaseolus coccineus L].

abstract：:Cell-suspension cultures were initiated from embryogenic calli of various barley cultivars. Seven fast-growing suspension lines were obtained from four different cultivars (cvs. Dissa, Emir, Golden Promise and Igri). Two of these cell suspensions showed morphogenic capacity.
