2009), the acropetal initiation and differentiation of primary branches produces homogenized and non- homogenized inflorescences; while species with basipetal differentiation of the primary branches (regardless of whether initiation is acropetal or basipetal) always show homogenized inflorescences.
Vascular connection between buds and root cutting of Esenbeckia febrifuga was established by an acropetal and basipetal differentiation of vascular tissues as observed in Machaerium stipitatum (Hayashi et al.
As the leaf grows, the drip tip remains more or less constant in size as the basipetal parts of the leaf lengthen and widen.
The direction of flower initiation is basipetal, at least on ultimate branches.
Moreover, Peoples and Matthews (1981) and Ashley (1972) found that the normal assimilate transport in sympodia is basipetal, and regardless of the fate of bolls at distal FS, bolls at FS 1 can still benefit from assimilates originating in subtending leaves at FS 2 and 3.
Some capitula, however, mature in a basipetal or centrifugal pattern (Cronquist, 1977; Payer, 1857) and are then logically termed "determinate inflorescences" (Classen-Bockhoff et al.
in which basipetal freezing also occurred (Pearce and Fuller, 2001).
In Vicia the position of the nucleus in relation to the tip is controlled by centrally located microtubules; the basipetal migration of the nucleus, however, appears to be controlled by actin microfilaments (Lloyd et al.
The top internode was markedly lighter than those below it, and the general trend was a basipetal increase in internode contribution to total dry matter.
However, a recent investigation of vascular development in Blechnum reports that vascular tissue is initiated first separately in the developing leaves and roots and that the stele becomes continuous by the subsequent basipetal development of interconnections among the strands (Gopalakrishnan & Nayar, 1990).
An increased rate of basipetal herbicide translocation through the phloem may relate to observed patterns of increased efficacy (Hart and Penner, 1993).
