    Notes: [Auszug] FLORAL ontogenesis has long been a preoccupation of morphologists. In trying to understand the physiological mechanism that underlies and determines the orderly formation of the several kinds of floral organs, it is essential to consider the organization and functional activities of the apex of the ...

    Generalizations on the Apical Meristem (1956)

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] ALTHOUGH the vegetative shoot apical meristems of vascular plants show very evident differences in histological organization, they all give rise to a vascularized leafy axis. That such apices have some organogenic property in common thus presents itself as an inescapable fact1. There is therefore a ...
