Аннотация:[Anomalous secondary thickening of the axial organs of the Centrosperms. (on the examples of the Amaranthaceae Juss.). 1. The concepts of thickening, thickening modes in some species]
A review of concepts about a mechanism of anomalous secondary thickening in the Сentrosperms is presented. A variety of patterns of the anomalous thickening has been revealed in the Amaranthaceous investigated. It has been concluded that some of the variants revealed conform to the concept of the successive bidirectional cambia, while others are more preferably explained by different versions of the concept of the unidirectional meristematic zone. It has been shown that the meristem of the anomalous thickening can arise through dedifferentiation of the pericyclic or phloem parenchym or directly from the apical meristem.
