Initiation of morphogenic cell-suspension and protoplast cultures of barley (Hordeum vulgare L.).

abstract：:Autolysis of the suspensor, an embryonal haustorium, starts in the basal cells and proceeds in the direction of the embryo. InPhaseolus vulgaris, acid phosphatase activity is first found in transforming plastids, similar to the acid phosphatase activity inPh. coccineus [Nagl (1977) Z. Pflanzenphysiol.85, 45-51], altho...
