Freezing proceeded acropetally and basipetally in root tissues and ice crystals were propagated throughout connected roots within seconds.
Br., the 1Br spikelets are initiated basipetally and end in a microtip (truncated long branch); while in other cases, such as in species of Cynodon, the 1Br spikelets are initiated amphipetally and end in a terminal spikelet (Liu et al., 2007).
In oat, as is typical in grasses, the lower internodes are the first to differentiate and elongate with the internodes elongating basipetally from the intercalary meristem of each internode (Kaufman et al., 1965).
Green and Goetz (1973), on the other hand, found that blade length increased basipetally across seven internodes for western wheatgrass [Pascopyrum smithii (Rydb.) Love] and blue grama [Bouteloua gracilis (H.
An extreme example of this delay is seen in Erigeron philadelphicus (Harris et al., 1991), in which the ray flowers are initiated basipetally, yielding a bidirectionally initiated inflorescence.
In a few even more extreme examples, some condensed heads mature neither acropetally nor basipetally and thus seem to have no discernable pattern of maturation at all.
