Ontogenesis and ontogenetic structure of cenotic populations of Eremurus anisopterus (Asphodelaceae) in the Kyzylkum desert (Uzbekistan)
New information about ontogenesis and ontogenetic structure of cenotic populations of the rarest endemic of Kyzylkum mountains Eremurus anisopterus (Kar. & Kir.) Regel is presented. Plant communities with participation of cenopopulations of the studied species are characterized. Duration of ontogenesis in natural conditions lasts more than 20 years. The vegetation cycle of E. anisopterus under Kyzylkum desert conditions lasts about five months, from March to July. The study showed that in different ecological and cenotic conditions of the Kyzylkum desert the E. anisopterus cenopopulations are normal but incomplete. Cenopulations in both studied plant communities (Eremerus–sagebrush and Eremurus–Peganum) are young. The ontogenetic spectrum is left-handed and coincides with the characteristic one. This, in general, reflects the biological features of E. anisopterus and indicates the stable state of the Kuldjuktau population of the species.
期刊介绍：
Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
