“…The chromosome number of 2n = 16 counted in the Bulgarian populations of P. brachiata corresponds to the data reported by Lomonosova (2005) for the population from Russia (Republic of Kalmytia, Manych Valley, Great Almaty Lake). Our results indicating a basic chromosome number of x = 8 correspond with those of Doulatyari et al (2009) and Ghaffari et al (2015) for the genus Petrosimonia. Karyotype asymmetry is a well-known parameter in karyological studies (Eroğlu 2015).…”

We studied karyological and morphological variability of the only representative of the genus Petrosimonia (Amaranthaceae) in Bulgaria and evaluated the current state of its populations in the country. The results indicated that Bulgarian populations of Petrosimonia brachiata have a diploid chromosome number of 2n = 16. In the population from the Pomorie Lake, the karyotype consists of six pairs of metacentric and two pairs of sub-metacentric chromosomes. In the population from the Atanasovsko Lake, satellites were observed on one pair of sub-metacentric chromosomes. Statistical analysis demonstrated that the main source of phenotype variation in the species is within the populations. Vegetative traits are more variable than generative ones. No significant variability was found in the studied quantitative characteristics or pollen morphology. Given the biological type of the species (annual) and its limited distribution in Bulgaria, the status of the two populations of P. brachiata cannot be regarded as stable, and the danger of a potential threat to them in the future is a possibility not to be excluded.

“…B. prostrata is a polyploid complex consisting of diploid (2n = 18), tetraploid (2n = 36) and hexaploid (2n = 54) cyto types. Diploid cytotype is more common and was established in different parts of the species area of distribution, tet ra ploid one was discovered in Kazakhstan (Zakhar'eva & Sos kov 1981) and China (Lomonosova et al 2014), hexaploid cytotype was known from Pakistan (Khatun 1991) and Iran (Ghaffari et al 2015).…”

“…Agriophyllum squarrosum is a diploid (2n = 18) summer annual mainly distributed in eastern and central Asia, including Mongolia, China, Kazakhstan, Azerbaijan, Dagestan, Iran and southcentral Russia (Zhao et al ., 2014; Ghaffari et al ., 2015). In China, the species is found mostly in the cool temperate zone especially in the north, and it has a close association with sandy deserts (Fig.…”

The seed ecology of Agriophyllum squarrosum, a pioneer sand dune annual in Central Asia, with particular reference to seed germination

In central Asia, Agriophyllum squarrosum is the first species to become established during natural succession on sand dunes. However, low germination percentages and thus poor stand establishment greatly inhibit the use of this key species in the stabilization of dunes. The aim of this review is to critically analyse published information on the seed biology of A. squarrosum with particular reference to identifying the factors limiting germination of seeds sown in the field. A conceptual model is used to illustrate the complexities of factors as well as the unknowns we found about the seed/seedling stage of the life cycle of this sand dune annual. A major result of this review is that we now know that high germination percentages can be obtained by storing freshly collected seeds dry at room temperatures for 2 to 3 months to allow dormancy break to occur via afterripening, and then storing them dry at low (e.g. 4–5°C) temperature to prevent them from entering secondary dormancy. Non-dormant seeds should be sown in the field in late spring when wind-blown sand will cover them, thus ensuring that they are in darkness, which promotes germination, at the time summer rains occur.
