Abstract

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.

吉林山地最稀有特有种异翅毛猴(Eremurus anisopterus)生殖种群的个体发生和个体发生结构新资料。和吉珥。)介绍了Regel。研究物种种群参与的植物群落特征。在自然条件下，个体发生持续时间可达20年以上。在Kyzylkum沙漠条件下，异翼龙的植被周期约为5个月，从3月到7月。研究表明，在不同的生态条件和地理条件下，异翅羚种群是正常的，但不完整。在两个被研究的植物群落(eremurus - sagebrush和Eremurus-Peganum)中，种群都是年轻的。个体发生谱是左旋的，与特征性谱一致。总的来说，这反映了异翼龙的生物学特征，表明了该物种在Kuldjuktau种群的稳定状态。

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.
