Open publisher page 13 citations

Abstract

Abstract A new technique is presented that allows to overcome very early embryo abortion after interspecific crosses. Embryogenic sectors of young fertilized ovules are cultivated in vitro on a solid/liquid double layer culture medium containing activated charcoal in the solid phase. Hybrid plans are obtained afer transfer the developed for the interspecific cross Cuphea paucipetala greenwooodii×C. laminuligera; but it is most likely also applicable to other combinations, even in different genera.
