Abstract Chenopodium album is a widespread ruderal plant that is used for food and medicinal purposes as a source of protein and valuable biologically active substances. The purpose of our research is to identify how artificial growing conditions affect the growth and development of Chenopodium album plants and the ability to accumulate primary metabolites in leaves. During the studies, a comparative morphometric analysis was carried out, as well as the analysis of ascorbic acid, protein quantitative content and antioxidant activity. The results were processed statistically. The studies have shown that it is necessary to use stratified seeds that have a higher germination capacity in sheltered soil. During their cultivation in sheltered soil under 16-hour lighting and artificial irrigation, Chenopodium album plants go through all stages of ontogenesis, up to flowering and fruiting during 45-50 days. Morphological analysis showed that metric growth parameters in cultivated plants (height, shoot biomass, leaf and generative organs biomass) are lower, and allometric growth parameters (reproductive effort and photosynthetic effort) are comparable to plant parameters from natural growing conditions. Artificial development does not significantly affect the accumulation of protein in the leaves of Chenopodium album and their antioxidant activity. At the same time, the synthesis of ascorbic acid is significantly reduced under artificial growing conditions.

The object of the study - Chenopodium album - is the plant that is widely distributed in Tatarstan along weedy places, the banks of water bodies, in settlements, along the roads in all natural areas (Sukhorukov, 1999; Bakin et al., 2000). The germination and germination energy of unstratified and stratified (at T = -10°C for 6 months) frost-blite seeds were determined in Petri dishes on filter paper and in pots with soil under 16-hour illumination and artificial irrigation. Seeds were germinated in 4-5 replicates of 50 pieces each for 10 (Petri dishes) and 120 days (pots with soil).

Email: [email protected] ABSTRACT Traditional medicine is widely used worldwide due to its benefits and healthier components that these natural herbs provide. Natural products are substances produced or retrieved from living organisms found in nature and often can exert biological or pharmacological activity, thus making them a potential alternative for synthetic drugs. Natural products, especially plant-derived products, have been known to possess many beneficial effects and are widely used for the treatment of various diseases and conditions. Dysphania ambrosioides is classified as an annual or short-lived perennial herb commonly found in Central and South America with a strong aroma and a hairy characteristic. Major components in this herb are ascaridole, p-cymene, α-terpinene, terpinolene, carvacrol, and trans-isoascaridole. Active compounds isolated from this herb are found to exert various pharmacological effects including schistosomicidal, nematicidal, antimalarial, antileishmanial, cytotoxic, antibacterial, antiviral, antifungal, antioxidant, anticancer, and antibiotic modulatory activity. This review summarizes the phytochemical compounds found in the Dysphania ambrosioides, together with their pharmacological and toxicological effects.

Using a previously published rbcL phylogeny of the Amaranthaceae–Chenopodiaceae alliance (Kadereit et al. 2003) and new ITS phylogenies of the Camphorosmeae and Salicornieae, we conclude that Australia has been reached in at least nine independent colonization events: four in the Chenopodioideae, two in the Salicornieae, and one each in the Camphorosmeae, Suaedeae, and Salsoleae. Where feasible, we used molecular clock estimates to date the ages of the respective lineages. The two oldest lineages both belong to the Chenopodioideae (Scleroblitum and Chenopodium sect. Orthosporum/Dysphania) and date to 42.2–26.0 and 16.1–9.9 Mya, respectively. Most lineages (Australian Camphorosmeae, the Halosarcia lineage in the Salicornieae, Sarcocornia, Chenopodium subg. Chenopodium/Rhagodia, and Atriplex) arrived in Australia during the late Miocene to Pliocene when aridification and increasing salinity changed the landscape of many parts of the continent. The Australian Camphorosmeae and Salicornieae diversified rapidly after their arrival. The molecular-clock results clearly reject the hypothesis of an autochthonous stock of Chenopodiaceae dating back to Gondwanan times.

  • Understanding the Weedy Chenopodium Complex in the North Central States
    UNDERSTANDING THE WEEDY CHENOPODIUM COMPLEX IN THE NORTH CENTRAL STATES BY SUKHVINDER SINGH DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Crop Sciences in the Graduate College of the University of Illinois at Urbana-Champaign, 2010 Urbana, Illinois Doctoral Committee: Professor Patrick J. Tranel, Chair Associate Professor Aaron G. Hager Associate Professor Geoffrey A. Levin Assistant Professor Matthew E. Hudson ABSTRACT The genus Chenopodium consists of several important weed species, including Chenopodium album, C. berlandieri, C. strictum, and C. ficifolium. All of these species share similar vegetative morphology and high phenotypic plasticity, which makes it difficult to correctly identify these species. All of these weedy Chenopodium species have developed resistance to one or more classes of herbicides. An experiment was conducted to determine if there is variability in response of Chenopodium species present in the North Central states to glyphosate. Our results indicate variable responses within and among the Chenopodium species. Species such as C. berlandieri and C. ficifolium had higher levels of tolerance to glyphosate than did various accessions of C. album. In another experiment, 33 populations of Chenopodium sampled across six North Central states were screened with glyphosate. The results showed variable responses to glyphosate within and among the Chenopodium populations. In general, the Chenopodium populations from Iowa were more tolerant, but some biotypes from North Dakota, Indiana and Kansas also had significantly high tolerance to glyphosate. Given there are species other than C. album that have high tolerance to glyphosate, and there are Chenopodium populations across the North Central states that showed tolerance to glyphosate, one intriguing question was to whether the Chenopodium populations were either biotypes of C.

ISSN 2153 733X LIPANDRA POLYSPERMA VAR. ACUTIFOLIA (CHENOPODIACEAE): A CORRECTION AND VALIDATION SERGEI L. MOSYAKIN M.G. Kholodny Institute of Botany National Academy of Sciences of Ukraine 2 Tereshchenkivska Street Kiev (Kyiv), 01601 Ukraine [email protected] ABSTRACT Lipandra polysperma (L.) var. acutifolia (Sm.) Mosyakin (Chenopodium acutifolium Sm.) (Chenopodiaceae) is validated with the correct citation of the basionym. The combination was published invalidly (Art. 41.5 of ICN ) in 2013, with an incorrect citation of Smith's publication. Corrected citations (grammatical gender, Art. 21.2 of ICN ) of two section-level combinations in Oxybasis Kar. & Kir. are also provided. Following the taxonomic re-circumscription of Chenopodium L. (Chenopodiaceae) and some other genera (including Lipandra Moq.) earlier usually considered synonyms of Chenopodium (Fuentes-Bazan & al. 2012), I proposed the new nomenclatural combination Lipandra polysperma var. acutifolia (Mosyakin 2013) for a widespread and rather distinct variety of the species. However, it has been done with an incorrect citation of the basionym: "Lipandra polysperma (L.) S. Fuentes, Uotila & Borsch var. acutifolia (Sm.) Mosyakin, comb. nov. Chenopodium acutifolium Sm., Comp. Fl. Brit.: 42. 1800." In fact, the cited publication did not contain the name Chenopodium acutifolium , which was published by Smith (1805) later. According to Art. 41.5 of ICN (McNeill & al. 2010), "[o]n or after 1 January 1953, a new combination, name at new rank, or replacement name is not validly published unless its basionym or replaced synonym is clearly indicated and a full and direct reference given to its author and place of valid publication, with page or plate reference and date."

  • Chenopodioideae, Chenopodiaceae/ Amaranthaceae): Implications for Evolution and Taxonomy
    Fruit and Seed Anatomy of Chenopodium and Related Genera (Chenopodioideae, Chenopodiaceae/ Amaranthaceae): Implications for Evolution and Taxonomy Alexander P. Sukhorukov1,2*, Mingli Zhang1,3 1 Key Laboratory of Biogeography and Bioresource in Arid Land, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi, Xinjiang, China, 2 Department of Higher Plants, Biological Faculty, Moscow Lomonosov State University, Moscow, Russia, 3 Institute of Botany, Chinese Academy of Sciences, Beijing, China Abstract A comparative carpological study of 96 species of all clades formerly considered as the tribe Chenopodieae has been conducted for the first time. The results show important differences in the anatomical structure of the pericarp and seed coat between representatives of terminal clades including Chenopodium s.str.+Chenopodiastrum and the recently recognized genera Blitum, Oxybasis and Dysphania. Within Chenopodium the most significant changes in fruit and seed structure are found in members of C. sect. Skottsbergia. The genera Rhagodia and Einadia differ insignificantly from Chenopodium. The evolution of heterospermy in Chenopodium is discussed. Almost all representatives of the tribe Dysphanieae are clearly separated from other Chenopodioideae on the basis of a diverse set of characteristics, including the small dimensions of the fruits (especially in Australian taxa), their subglobose shape (excl. Teloxys and Suckleya), and peculiarities of the pericarp indumentum. The set of fruit and seed characters evolved within the subfamily Chenopodioideae is described. A recent phylogenetic hypothesis is employed to examine the evolution of three (out of a total of 21) characters, namely seed color, testa-cell protoplast characteristics and embryo orientation.

  • The Economic Potential of Chenopodwm Berlandieri in Prehistoric Eastern North America
    J. Ethnobiol. 7(1):29-54 Summer 1987 THE ECONOMIC POTENTIAL OF CHENOPODWM BERLANDIERI IN PREHISTORIC EASTERN NORTH AMERICA BRUCE D. SMITH Department of Anthropology National Museum of Natural History Smithsonian Institution Washington, D.C. 20560 ABSTRACT.-A thin-testa domesticate chenopod (Chenopodium berlandieri ssp. jonesi­ anum) was present in the eastern woodlands of North America by approximately 3500 BP., and this cultigen subsequently became one of the more important components of pre-maize plant husbandry systems in the East. The economic potential of this prehistoric domesticate can be projected through harvest studies of present day wild/weedy stands of Chenopodium berlandieri. During the fall of 1984 and 1985 a total of 86 plants located in nine states were harvested, with timed harvest hand stripping experiments carried out on 16stands. Harvest yield values varied from 276 kglha to 2854 kglha. Harvest rate values ranging from .41 kg/hr to 1.6 kglhr were recorded. Relatively conservative harvest yield and harvest rate values of 750-1500 kg/ha and 0.7 - 1.1 kg/hr are proposed for C. ber­ landieri in the prehistoric eastern woodlands, and when a seed coat thickness correction factor is applied, the resultant relatively conservative harvest yield range estimate of 500 - 100 kg/ha is found to favorably compare to quinoa and maize, as well as other eastern pre-maize cultigens. INTRODUCTION RESEARCH DESIGN The tropical cultigen triad of com} beans} and squash often is considered the core of prehistoric plant husbandry in Eastern North America} and these three crops were certainly of substantial economic importance during the late prehistoric period.
