basipetal

  1. (of a stem) producing structures one after the other from the apex down to the base, so that the oldest are at the apex.
  2. (of substances, e.g. AUXINS) movement away from the apex to lower parts of the plant.

In species of the PCK clade (Reinheimer et al., 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.
(2009) have correlated the acropetal initiation of primary branches with the presence of a determinate symmetry type; and the basipetal initiation of primary branches with an unstable simetry, that is, the existence of different types of symmetry among inflorescences within one species.
In canola, flowering takes place in acropetal succession, while branching takes place in basipetal succession (Mendham and Salisbury, 1995).
Order of flower initiation generally differs in determinate and indeterminate inflorescences: basipetal in the former; acropetal in the latter.
These results disagree with the findings of Peoples and Matthews (1981) and Ashley (1972) that the only direction for transport of assimilates in sympodia is basipetal. Although having a lone boll at FS 3 did not consistently reverse the predominance of this effect, in some situations FS 3 did benefit from fruit loss at proximal FS.
At times, the lag in peripheral flower initiation and development is so pronounced as to produce a bidirectional pattern with regard to the ray flowers (basipetal) and the disk flowers (acropetal) (Harris et al., 1991), as seen in Erigeron philadelphicus L.
Immediately following this stage, the primary capitula begin to differentiate in a basipetal sequence (Classen-Bockhoff, 1992).
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., 1987).
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).
Several authors have illustrated that internode development is acropetal in dicots and basipetal in monocots primarily due to the location of intercalary meristems (Evans, 1965; Sachs, 1965; Kaufman et al., 1965; Garrison, 1973; Easu, 1977; Morrison et al., 1994).
