Karyological and morphological variations within Blitum Virgatum L. ( Chenopodiaceae ) in Bulgaria

Abstract

ABSTRACTЕight populations of Blitum virgatum L., belonging to 5 different phytogeographic regions have been karyologically and morphologically tested. Intrapopulation and interpopulation variability have been traced. The rеlationship between morphological and karyological variability, ecological, and geographic appurtenance of the studied populations has been explored. The main source of phenotype variation in all population is the interpopulation variation. Interpopulation differences are influenced by the differences in karyotypes, environmental conditions and composition of communities.

Karyological study of genus Bassia All. in Bulgaria

“…The karyotype morphology of the species is reported for the first time from Bulgarian populations. The chromosome number 2n = 18 confirms the previous results from Bulgaria -Northern Black Sea Coast, Schablensko Lake and Southern Black Sea Coast, Poda Protected Area (12). The results obtained correspond also to the data reported by the other authors (15)(16)(17)(18).…”

Studies on the Bulgarian members of the family Chenopodiaceae s. stricto: a review

“…Van Loon and Van Setten (1982) reported for Blitum virgatum populations from Shipka, Central Stara planina diploid chromosome number 2n = 18. These data were ( confirmed by Grozeva and Stoeva (2006) for other populations of the species from Central Stara planina, Western Rhodopes and Tundzha hilly country by Grozeva and Cvetanova (2016) as well as for populations from Rila, Western and Central Rhodopes, Belasitsa, Tundzha hilly country. Grozeva and Stoeva (2006) published for the first time chromosome numbers for 4 species from the family Chenopodiaceae, as follows: diploid chromosome number 2n = 18 for Bassia hirsuta and Corispermum nitidum for populations from the Southern Black Sea coast and for Dysphania botrys from the Danubian plain, North-Eastern Bulgaria and Central Stara planina; tetraploid chromosome number 2n = 32 for Dysphania ambrosioides populations from the Danubian plain and the Thracian lowland.…”

“…Detailed studies on the morphology of Chenopodiaceae in Bulgaria were conducted, mainly on Chenopodium s. lat. In particular, the following species were investigated: Chenopodium album and Dysphania botrys from 18 populations (Grozeva and Cvetanova 2008), Blitum bonus-henricus from 10 populations with ecological notes (Grozeva and Cvetanova 2011) and distribution in the country (Grozeva 2011), C. pratericola (Grozeva 2012a), the genus Dysphania (Grozeva and Cvetanova 2013), C. probstii and C. missouriense (Grozeva 2014), Blitum virgatum (Grozeva and Cvetanova 2016). Further taxa studies were Bassia hirsutа (Grozeva and Todorova 2014) and Petrosimonia brachiata (Grozeva et al 2019a).…”

“…The karyological variability was traced and the karyotype of Blitum virgatum (Grozeva and Cvetanova 2016), of the species from genus Salsola (Grozeva et al 2018) and genus Atriplex (Grozeva 2018a) was established. Grozeva and Atanassova (2019) studied the karyotype of Chenopodiastrum murale and Ch.…”

Taxonomic significance of pollen morphology of selected taxa of Bassia , Sedobassia , Spirobassia and Neokochia (Chenopodiaceae/Amaranthaceae sensu APG IV)

“…Pollen grains of some species of these genera were studied using light microscopy (LM) and scanning electron microscopy (SEM) (Kupriyanova and Alyoshina 1972, Monoszon 1973, Nowicke 1975Chung and Lee 1996;Tsymbalyuk 2005Tsymbalyuk , 2008Tsymbalyuk et al 2005;Al-Turki et al 2008;Perveen and Qaiser 2012;Akhani and Khoshravesh 2013;Angelini et al 2014;Grozeva and Todorova 2014). The PalDat online database contains some information on pollen of B. laniflora and B. prostrata that were studied using LM (Auer 2021;Diethart and Auer 2021) and B. scoparia that were studied using LM/SEM and transmission electron microscopy (Heigl 2021).…”
