Experimental Embryology of Gymnosperms,n turn, are subdivisions relating to experimental approaches (via microsurgery, embryo culture, etc.) as well as those treating special groups of plants. Not the least of the latter are the gymnosperms, in which interest may be attributed to two features: their undeniable fascination to botanists be

Flower Culture,ogenetic activities occur in this short life-span of an angiosperm flower. Floral initiation and development have been delineated as two distinct processes by Nitsch (1965), and Evans (1969). Although a large volume of data has accumulated on flower initiation, most of the information on development

Despite many years of experimentation, however, embryos at very early stages of development have not proved amen
