Abstract:The effects of six kinds of auxins on in vitro morphogenesis ofanthers in Hyoscyamus niger were observed,Fifteen gradient concentrations(0.01-100mg/L) per auxin were also tested.It is evident from the results thatembryogenesis and organogenesis were promoted by exogenonsly supplie six ki-nds of auxins.The relative effects of auxins on pollen embryoids may beexpressed in the order of IBA>NAA>IAA>NOA>2,4,5-T>2,4-D.The embr-yogenesis was promoted by auxin at low concentration and inhibited at highconcentration.2,4-D,NOA and 2,4,5-T can both produce embryoid and callus,the others,IAA,IBA,few of them can produce callus even in low concentratioa.Upon transfer the callus to basal medium after 2-3 wk,it showed embr-yogenesis and organogenesis two kinds of developmental pathway.NOA stimulated root and bud formation from callus even in high concentration(80mg/L)and the differential rate of organogenesis is higher than embryogenesis.Thedifferential ability of callus decreased conspicuosly by duration of 2,4-D.
