Intra-Individual and Intraspecific Terpenoid Diversity in Erodium cicutarium

The chemodiversity between and within individuals of several plant species is remarkable and shaped by the local habitat environment and the genetic background. The forb Erodium cicutarium (Geraniaceae) is globally distributed and partly invasive. This paper hypothesizes a high intra-specific and inter-individual chemical diversity in this species and investigates this by comparing the concentration and diversity of terpenoid compounds in different plant parts, i.e., leaves, blossoms and fruits. Plants were grown from seeds, originating from native range Bavaria (BY), Germany, and invaded range California (CA), USA, populations. In total, 20 different terpenoids were found, which occurred in distinct combinations and the patterns clustered into groups of distinct chemotypes for all plant parts. Several of the chemotypes were specific to plants of one region. The terpenoid compositions of different plant parts within individuals were highly correlated. Chemodiversity was higher in reproductive plant parts compared to the leaves, and higher in plants from BY compared to CA. This study highlights the intra-specific and inter-individual chemodiversity in E. cicutarium, linked to its geographical origin, which may facilitate its invasion success but also calls for further investigation of the role of chemodiversity in invasive plants on interactions with the environment.

Ethnopharmacological application the plants from family Geraniaceae in the Pirot County

The subject of this study was the study of the ethnopharmacological application of plants from family Geraniaceae in the Pirot County (Southeastern Serbia). The research was conducted in the form of surveys among the rural population in four municipalities: Pirot, Babušnica, Bela Palanka, and Dimitrovgrad. The analysis of the survey showed that the population of the County was used Erodium cicutarium (1 report), Geranium macrorrhizum (7 reports), Geranium robertianum (1 report), and Pelargonium graveolens (1 report) in the folk medicine for internal application. Erodium cicutarium was used against spasms in the abdomen of children (1 report), Geranium macrorrhizum against bronchitis (2 reports), diabetes (1 report), for rejuvenation (1 report), high blood pressure (2 reports), and Parkinson' s disease (1 report), and Pelargonium graveolens against diabetes (1 report). One respondent has mentioned the use of Geranium robertianum, but without the knowledge about its use. The results were compared with the results of previous ethnobotanical studies in neighboring regions. Our results about the applications of species from the family Geraniaceae are completely different from their ethnobotanical surveys in Serbia and the Balkan Peninsula.

SPECIES COMPOSITION OF WEEDS IN RAPESEED CROPS IN GEOGRAPHICALLY REMOTE REGIONS ON THE EXAMPLE OF LIPETSK AND SVERDLOVSK REGIONS

The aim of the study is to identify differences in the species composition of weeds in spring rapeseed crops in two geographically remote regions of the Russian Federation – Lipetsk (Central black earth region) and Sverdlovsk (Ural region). The analysis was carried out using methods of comparative Floristics and distribution of species by classes of constancy of occurrence. Differences between segetal weed flora elements in the agrophytocenoses of canola compare regions, as in floral structure, consisting of the first two "triads" of the floristic spectra and confirmed the low rate coefficient of species similarity. Species differences are represented by species that pollute rapeseed crops only in one of the compared regions. Among the species common to the agrophytocenoses of rapeseed in the two regions are such species as, Chenopodium album L., Echinochloa crusgalli (L.) Beauv., Silene praténsis (Rafn) Godr., Euphorbia helioscopia L, Fallopia convolvulus (L.) A. Loeve, Viola arvensis Murr. they are characterized by higher rates of occurrence in the Lipetsk region, and Capsella bursa-pastoris (L.) Medik., Cirsium setosum (Willd.) Bess, Erodium cicutarium (L.) L. Her., Thlaspi arvense L. – in the Sverdlovsk region. The dominant species in the Lipetsk region are Raphanus raphanistrum L., Chenopodium album L., Echinochloa crusgalli (L.) Beauv., Silene praténsis (Rafn) Godr., and in the Sverdlovsk region - Galium vaillantii DC., Stellaria media (L.) Vill., Capsella bursa-pastoris (L.) Medik., Thlaspi arvense L., Chenopodium album L., Cirsium setosum (Willd.) Bess. To protect rapeseed crops from weeds in different regions that differ in terms of heat and moisture availability, it is necessary to develop regional protection systems, preceded by mandatory monitoring studies.

Muilla lordsburgana (Asparagaceae: Brodiaeoideae), a new species found north of Lordsburg, southwestern New Mexico

Muilla lordsburgana P.J.Alexander sp. nov. is described from eastern Lordsburg Mesa in the northwestern fringe of the Chihuahuan Desert, southwestern New Mexico. It is very similar to Muilla coronata, a species known in the Mojave Desert of California and a small area of adjacent Nevada. Compared to Muilla coronata, the style and stigma combined are longer, the anthers are longer, the fruits are larger, and the seeds are larger. It has a short flowering period in March, and is difficult or impossible to find at other times of the year. It is narrowly distributed, limited to a band of deep, coarse, sandy soils derived primarily from granite. Several species that are otherwise uncommon in the area also occur in this habitat, including Logfia depressa, Pectocarya platycarpa, and Plagiobothrys arizonicus. Invasive species, especially Erodium cicutarium in the winter annual flora, are generally dominant. Muilla lordsburgana has probably been overlooked until now because it is not easy to observe and occurs in habitats that are not attractive to botanists.
