The History Of Germinating Embryos Of The Eastern Dwarfmistletoe (Arceuthobium Pusillum Peck), Frank H. Tainter

Journal of the Minnesota Academy of Science

Embryos of germinating seeds of Arceuthobium pusillum have four histological zones: the protoderm of the radicular apex, which remains distinct throughout germination and through anticlinal divisions gives rise to the epidermis; the procambium, which matures into a simple vascular strand in the mature radicle; the ground meristem, which matures into the cortex; and the promeristem, from which the procambium and ground meristem are derived.
