Aging of Meristems and Morphogenetic Potentialities

Abstract

The term “aging” refers to chronological changes in plants. In many plants requiring a maturation period, morphogenetic potentialities of meristems may change during aging until flowering and later on, until death. These changes induce “heteroblastic development” (Goebel, 1889). As plants display different morphogenetic qualities along the shoot, an ascendent gradient of aging has been suggested. Molisch (1938) called this phenomenon “topophysis” (from the Greek topos = location and physis = nature) to point out the different morphogenetic potentialities of meristems located at different places. The same phenomenon was referred later on as “physiological aging of meristems” (Schaffalitzky, 1959). The aging of meristems can be defined as the qualitative changes induced by internal and/or environmental factors on morphogenetic potentialities resulting in flowering and the loss of proliferation capacity which leads to senescence.
