Along the Rivers and into the Plain: Early Crop Diversity in the Central and Western Balkans and Its Relationship with Environmental and Cultural Variables

Agriculture is a complex and dynamic socio-ecological system shaped by environmental, economic, and social factors. The crop resource pool is its key component and one that best reflects environmental limitations and socio-economic concerns of the farmers. This pertains in particular to small-scale subsistence production, as was practised by Neolithic farmers. We investigated if and how the environment and cultural complexes shaped the spectrum and diversity of crops cultivated by Neolithic farmers in the central-western Balkans and on the Hungarian Plain. We did so by exploring patterns in crop diversity between biogeographical regions and cultural complexes using multivariate statistical analyses. We also examined the spectrum of wild-gathered plant resources in the same way. We found that the number of species in Neolithic plant assemblages is correlated with sampling intensity (the number and volume of samples), but that this applies to all archaeological cultures. Late Neolithic communities of the central and western Balkans exploited a large pool of plant resources, whose spectrum was somewhat different between archaeological cultures. By comparison, the earliest Neolithic tradition in the region, the Starčevo-Körös-Criş phenomenon, seems to have used a comparatively narrower range of crops and wild plants, as did the Linearbandkeramik culture on the Hungarian Plain.

Wild Plant Habitat Characterization in the Last Two Decades in the Nile Delta Coastal Region of Egypt

Environmental and land-use changes put severe pressure on wild plant habitats. The present study aims to assess the biodiversity of wild plant habitats and the associated spatiotemporal environmental changes in the coastal region of Dakahlia Governorate following an integrated approach of remote sensing, GIS, and samples analysis. Thirty-seven stands were spatially identified and studied to represent the different habitats of wild plants in the Deltaic Mediterranean coastline region. Physical and chemical characteristics of soil samples were examined, while TWINSPAN classification was used to identify plant communities. Two free Landsat images (TM and OLI) acquired in 1999 and 2019 were processed to assess changes via the production of land use and cover maps (LULC). Moreover, NDSI, NDMI, and NDSI indices were used to identify wild plant habitats. The floristic composition indicated the existence of 57 species, belonging to 51 genera of 20 families. The largest families were Asteraceae, Poaceae, and Chenopodiaceae. The classification of vegetation led to the identification of four groups. Canonical Correspondence Analysis (CCA) revealed that electrical conductivity, cations, organic carbon, porosity, chlorides, and bicarbonates are the most effective soil variables influencing vegetation. The results of the spectral analysis indicated an annual coverage of bare lands (3.56 km2), which is strongly related to the annual increase in vegetation (1.91 km2), water bodies (1.22 km2), and urban areas (0.43 km2). The expansion of urban and agricultural regions subsequently increased water bodies and caused occupancy of bare land, resulting in the development of wild plant habitats, which are mostly represented by the sparse vegetation class as evaluated by NDVI. The increase in mean moisture values (NDMI) from 0.03 in 1999 to 0.15 in 2019 might be explained by the increase in total areas of wild plant habitats throughout the study period (1999–2019). This may improve the adequacy of environments for wild habitats, causing natural plant proliferation.

Rock Samphire, a Candidate Crop for Saline Agriculture: Cropping Practices, Chemical Composition and Health Effects

The recent market trends for functional healthy foods have rekindled the interest in wild edible species and created a market niche for high added value products. The current supply, mainly supported by plants collected from the wild, cannot meet increasing market needs; therefore, it is of major importance to establish cropping protocols and further valorize wild plants for culinary and industrial applications. Sea fennel is a wild edible halophyte that is an important ingredient in local cuisines and is also used in folk medicine for its beneficial health effects. Its valorization has not been commercially explored on a great scale and more efforts are needed to integrate the species in farming systems. The present review compiles the most recent reports regarding the farming practices that could allow for the establishment of cultivation protocols for farmers, while the main constraints that hinder the further exploitation of the species are also presented. Moreover, this review presents the most up-to-date information regarding the chemical composition (e.g., chemical composition of the aerial parts and volatile compounds in essential oils) and the health-related effects of various plant parts (e.g., antimicrobial, insecticidal and anticholinesterase activities) aiming to reveal possible alternative uses that will increase the added value of the species and will contribute to its commercial exploitation. Finally, the future remarks and the guidelines that have to be followed are also discussed.

Food Behavior in Emergency Time: Wild Plant Use for Human Nutrition during the Conflict in Syria

Wild food plants (WFPs) have been an important source of human nutrition since ancient times, and it particularly revives when conventional food is not available due to emergency situations, such as natural disasters and conflicts. The war in Syria has entered 10 years since it started in 2011, and it has caused the largest war-related crises since World War II. Nearly 60% of the Syrian population (12.4 million people) are food-insecure. WFPs are already culturally important in the region, and may be supplementing local diets during this conflict. Our study aimed to uncover the conflict’s effect on the use of WFPs and to know what species are consumed by local people during the current crisis. The fieldwork was carried out between March 2020 and March 2021 in the Tartus governorate located in the coastal region of Syria. Semi-structured interviews were conducted with 50 participants (26 women and 24 men) distributed in 26 villages along the study area. We recorded the vernacular names, uses, plant parts used, modes of preparation and consumption, change in WFP use before and during the conflict, and informants’ perceptions towards WFPs. We documented 75 wild food plant species used for food and drink. Almost two-thirds (64%) of informants reported an increase in their reliance on wild plants as a food source during the conflict. The species of Origanum syriacum, Rhus coriaria, Eryngium creticum, and Cichorium intybus were among the most quoted species by informants. Sleeq (steamed leafy vegetables), Zaatar (breakfast/dinner food), and Louf (soup) were the most popular wild plant-based dishes.

Ethnobotanical study on plants used to dye traditional costumes by the Baiku Yao nationality of China

Background The Baiku Yao is a branch of the Yao nationality in China. The unique dying process of traditional clothing employed by these people has distinct national characteristics, a profound impact on the production and life of local people, and important research value. For this reason, it is important to investigate and document the dyeing plants and the traditional knowledge involved in the dyeing of Baku Yao traditional clothing. Methodology Information on dyeing plants was obtained using the free-list method and interviews with 61 Baiku Yao informants in Guangxi and Guizhou from January 2020 to August 2021. Based on the free-list method, we evaluated and screened out important plants by calculating the cognitive salience value of each plant. Results The results showed that the people of Baiku Yao have accumulated rich traditional knowledge of dyeing plants and long-term dyeing and other processes. We collected 23 species and recorded the related traditional knowledge, such as the Baiku Yao name, life form, habitat, part(s) used, application type, usage, and area used. The utilization of dyeing plants has a strong relationship with ethnic culture. The Baiku Yao uses unique anti-dyeing material (Ailanthus vilmoriniana) in the cotton dyeing process, they call it “the mother tree”. As well as, the results also showed that 15 plants (65.2%) have medicinal value and can be used to treat 18 aliments, and wild plants play a very important role in the life of the Baiku Yao. Conclusion These plants not only meet the color needs of the Baiku Yao people but also have health care effects, aligning with the trends toward green dyeing and the health contentiousness of modern people. This study provides a reference for the inheritance and development of Baiku Yao traditional clothing dyeing culture, will aid the identification of new natural, safe and healthy textile dyes, and is of positive significance in promoting regional economic development, national cultural inheritance, and biodiversity protection.

Functional bread enreached with regional bioactive food additives

The scientific work presents materials of theoretical and experimental substantiation of the use of regional bioactive food additives, namely wild plants of the legume family (Fabaceae), permitted for use in the food industry: sweet clover (Melilotus officinalis), red meadow clover (Trifolium pratense), white acacia (Robinia pseudoacacia) in the production of functional foods [1]. Experimental studies of the safety indicators of food wild-growing plants (FWP) have been carried out. It was found that the studied FWP growing in ecologically clean areas of the North Ossetia-Alania are distinguished by a low mass fraction of toxic substances. Two fractions of cellulose were investigated: 1 - water-soluble (pectic acid, pectin, methylcellulose); 2 - water-insoluble (protopectin, cellulose, hemicellulose). The increased content of dietary fiber in WGP powders has been established, corresponding to the physiological norms of satisfying the daily requirement for FWP and, in this regard, indicating the expediency of using functional food in formulations for the prevention and treatment of diabetes mellitus, obesity, and atherosclerosis. The sorption capacity of WGP powders with respect to lead has been investigated. All studied powders of WGP modification products are characterized by high sorption capacity. The technologies of flour products with the addition of FWP powders have been developed. The results of clinical and preclinical studies of the developed functional bread show a corrective effect of glycemic blood parameters, as well as a decrease in the lead content in the blood of fed laboratory rat pups by almost two times, compared with the control.

Process approach to organization of wild processing business

The study examines the organization of a new business for the harvesting and processing of wild plants based on the development of traditional industries, trades and crafts of rural residents. As process solutions, a block of design justifications is presented, aimed at developing practical measures on the stated topic. In particular, the emphasis is placed on the economic justification and social significance when organizing a business for processing wild plants. In the substantive part of the study, a model for calculating capital investments is presented; sources of financing for a business project are indicated. Separately, it is worth highlighting the element of practical implementation, including the technical modernization of the production process of processing raw materials, namely, the improvement of the technological process through the use of microwave vacuum drying technology. The calculation of the need for personnel is performed; the possible qualification requirements for employees are indicated. The research of the market of similar products based on information search was carried out. An overview of the average retail prices is made according to the Internet portal “Russian agro-industrial server Agroserver.ru”, on the basis of which the forecasted amounts of proceeds from sales and the expected profit from organizing a business for processing wild plants are calculated. Significant expected results are: an increase in the standard of living of the population collecting and harvesting wild plants; providing employment in rural areas; saturation of the market with products of wild plants; strengthening of competitive positions; saturation of the market with locally produced products; increasing the profitability of regional and local budgets. It is assumed that at the initial stage, the manufactured products will be sold mainly in the region. The sale will be carried out through trade networks, as well as in markets, stationary retail outlets, fairs, exhibitions, the main consumers of the products will be the population of the Kemerovo region.

Exploration and morphologic variation of Iris wild species with ornamental potential

Nowadays, the flower industry is growing so fast that its development requires introducing new varieties to the flower market. Iran is the habitat of numerous species of wild plants that are among the valuable genetics in the breeding process. The identification of native Iris species, investigation of morphological diversity, and distribution method have a significant effect on the introduction of this flower as new and superior cultivars cut flower and bedding plant. The documentation of the most important habitats of Iris in Arak province, identification of morphological characteristics and correlation determination of morphological traits are the most important aims of this research. The results showed that there is a correlation between some of the traits. The highest positive correlation was related to the height of flower and length of the leaf, length of the flowering stem and the length of the leaf and the height of the flower and the length of the flowering stem. The ecotypes of Iris sp. were divided into six groups. Based on the results of the cluster diagram, the bulbous species were separated from rhizome species. Generally, due to the color diversity of Iris sp. and unique beauty of the flowers and the resistance of the native species, they can be used as native foundations. Due to the prominent traits such as high durability of Iris meda, odor of I. hymernospatha Subsp. leptoneura and color diversity of I. persica, I. songarica and height of I. spuria, they can be used to introduce new ornamental species. Iris spuria is the most suitable genotype because of the high height, large flower, high durability, and beautiful flower.

Plant economy of the Trzciniec culture based on charred plant remains from Pielgrzymowice 9 site, in the context of archaeobotanical finds from southern Poland

In the paper, new carpological data from Pielgrzymowice site 9 are presented in the context of archaeobotanical finds from southern Poland. The results were obtained from detailed analyses of 45 samples from 38 archaeological features. Only charred plant remains were taken into account as they are considered contemporaneous with the Middle Bronze Age settlement. Among the cultivated plants, Panicum miliaceum, Triticum dicoccum, Triticum monococcum and Triticum sp. were documented. Among wild plants, several taxa were found, including Chenopodium t. album, Chenopodium sp., Melandrium / Silene, Polygonum lapathifolium and Fallopia convolvulus, among others. In archaeobotanical samples, Geranium sp., cf. Lamiaceae also appeared. In addition, plants typical of grasslands, forests and ruderal areas were noted, such as Coronilla varia, Rumex acetosella, Plantago media, Plantago lanceolata, Stellaria graminea and Hypericum perforatum. These results were compared with data coming from nine sites of the Trzciniec culture from Lesser Poland to track the Middle Bronze Age plant-based economy in southern Poland.

Dynamics of the Species Composition of Phytocenoses of Floodplain Mountain Meadows of the Carpathians Subject to Superficial Improvement

The conducted research of various authors has developed a number of measures for surface improvement of meadowland in various soil and climatic conditions. However, studies on the influence of such surface improvement measures as the use of organic and mineral fertilizers and sowing of perennial grasses and legumes in the sod on the dynamics of the species composition of Floodplain Mountain meadows of the Carpathians have not yet been conducted, which confirms the relevance of this study. The article presents the results of three-year studies conducted during 2017-2019 in the peasant farm of V.F. Martyshchuk (the Verkhovinsky District of the Ivano-Frankivsk region) to study the features of transformation of the species composition of natural phytocenoses of floodplain Meadows of the Black Cheremosh river of the mountain and forest belt of the Carpathians under the influence of their surface improvement with the use of organic and mineral fertilizers and sowing of a cereal mixture for haymaking use and Tribolium repens L. for multipurpose use. It was found that floodplain Meadow phytocenoses were mainly cereals and mixed grasses with a share of wild cereals of 57-58% (up to 15 of them % Festuca rubra L. s. str. and 5-6% of low-value ones in feed terms Calamagrostis arundinaceae (L.) Roth and Deschampsia caespitosa (L.) Beauv.), mixed grasses – 35-38% and unseeded Fabaceae 5-7%. When applying a set of measures for surface improvement of cereals and mixed grasses, low productive (within 1.95-2.15 t/ha of dry weight) floodplain mountain meadowlands, their species composition improved. For making P30K60 the content of wild plants increased by 2-5% Fabaceae, and N60P30K60 – by 9-10% unseeded Poaceae. For haymaking use, Poaceae with Phleum pratense L. and Festuca pratensis Huds. against the background of making N60P30K60 for sowing a mixture in the sod in the spring, their share increased to 74%, and for multi-year use and sowing Trifolium repens L. against the background of making P30K60 the quantity of Fabaceae increased to 44% or by 32%. The highest floral saturation (43 species from 19 families and 93-98% from perennials) was observed in variants without fertilization and with the introduction of P30K60 for multi-year use, which is 4-14 species more compared to haymaking use, or with the introduction of N60P30K60 and or with sowing a mixture of cereals on the background of N60P30K60 for haymaking use, or sowing Trifolium repens L. against the background of P30K60 for multipurpose use
