Abstract
There is a lapse of several days before rhizoids are produced from the zygote of H. siliquosa (L.) Lyngb. In order to remain attached to the substratum until this time, the zygote rapidly secretes a rigid adhesive zygote wall with associated adhesive mucilages. The cell wall proper is laid down inside this zygote wall. A multicellular spherical germling develops and once the rhizoid system has formed, the zygote wall is shed from the thallus in the form of a cap. Four primary rhizoids are followed by the production of more rhizoids throughout the life of the plant and in this way the holdfast of the adult is built up. These events were followed using the techniques of light, scanning and transmission electron microscopy.This publication has 0 references indexed in Scilit:
