in a carrot ( daucus carota l. ) cell line lacking the ability to undergo somatic embryogenasis , and in carrot and anise ( pimpinella anisum l. ) cell lines in which embryogenesis could be regulated by presence or absence of 2,4-dichlorophen-oxyacetic acid ( 2,4-d ) , in the medium ( +2,4-d=no embryogenesis , -2,4-d=embryo differentiation and development ) , the levels of endogenous gibberellin ( s ) ( ga ) were determined by the dwarfrice bioassay , and the metabolism of [ ( 3 ) h ] ga1 was followed .
