Biology of flowering and embryological structure of the iron tree in aderonic conditions
Abstract
The article studies the development of the reproductive organs of iron tree, which belongs to the relict flora of the third period. It has been established that Parrotia persica has no serious obstacles that impede the normal process of seed formation. The flower group of this succulent species is almost devoid of cover. Moreover, it is mainly formed during the winter season, which limits the introduction of the plant into more severe climatic zones. İn the Absheron Peninsula, iron trees bloom and bear fruit only in years with mild winters, strong winds and the absence of night frosts. Embryological studies have established correspondence between the functions of the epidermis and endothecium, the presence in males of a clearly visible valve, in which the nuclei of the tapetal cells are located linearly in the radial direction, as well as a delay in the development of the female genital organs compared to the male system.
