Keragaman Jenis Tanaman Pada Dua Sistem Pertanian di Pegunungan Arfak Papua Barat
2021
The geographical of Pegunungan Arfak Regency was at 1200 - 2300 meters above sea level, has a mountainous topography, potential for the development of economic highlands crops. The aim this research was to see the diversity of cultivated plant by Arfak people at Arfak mountainous in their field and yard farming system. These studies were conducted at 2 Districts: 1) Anggi: Testega, Bamaha and Kostera Village; 2) Anggi Gida at Tuabiam Village of Pegunungan Arfak Regency. The data collected by survey technique. The results showed there were a diversity of cultivated plants at two different farming system by Arfak people. There were 30 cultivated plants in four villages; consisted of 9 types …
Copper binding capacity of root exudates of cultivated plants and associated weeds
2001
International audience; Cu binding to root exudates of two cultivated plants, wheat (Triticum aestivum) and rape (Brassica napus), and two weeds associated with wheat, dog daisy (Matricaria inodora) and cornflower (Centaurea cyanus), was studied in vitro under hydroponic and sterile conditions. Nutrient solutions were prepared with or without P. A MetPLATE microbiological test was used to assess the metal complexing capacity of root exudates. In the P-deficient solutions, no exudation was observed for any of the four plants; consequently, no Cu binding occurred. When P was present in the nutrient solutions, the plant exudates displayed differing abilities to complex Cu. No difference was de…
Human fascioliasis infection sources, their diversity, incidence factors, analytical methods and prevention measures
2018
AbstractHuman fascioliasis infection sources are analysed for the first time in front of the new worldwide scenario of this disease. These infection sources include foods, water and combinations of both. Ingestion of freshwater wild plants is the main source, with watercress and secondarily other vegetables involved. The problem of vegetables sold in uncontrolled urban markets is discussed. Distinction between infection sources by freshwater cultivated plants, terrestrial wild plants, and terrestrial cultivated plants is made. The risks by traditional local dishes made from sylvatic plants and raw liver ingestion are considered. Drinking of contaminated water, beverages and juices, ingestio…
Variability of Hypericins and Hyperforin in Hypericum Species from the Sicilian Flora
2019
Within Sicilian flora, the genus Hypericum (Guttiferae) includes 10 native species, the most popular of which is H. perforatum. Hypericum's most investigated active compounds belong to naphtodianthrones (hypericin, pseudohypericin) and phloroglucinols (hyperforin, adhyperforin), and the commercial value of the drug is graded according to its total hypericin content. Ethnobotanical sources attribute the therapeutic properties recognized for H. perforatum, also to other Hypericum species. However, their smaller distribution inside the territory suggests that an industrial use of such species, when collected from the wild, would result in an unacceptable depletion of their natural stands. This…
A new species of Centaurea (Asteraceae) from Calabria(S Italy)
2013
A new species is described here from the Presila in Calabria (S Italy) and named Centaurea calabra. It belongs to Centaurea sect. Phalolepis and is related to the C. deusta group, namely to C. sarfattiana. Taxonomical characteristics, distribution, and ecology of the new Centaurea are also provided.
Ethnobotany of the Aegadian Islands: safeguarding biocultural refugia in the Mediterranean
2021
Abstract Background The Aegadian Islands are located west of Trapani, Sicily. Once the site of bountiful tuna fisheries and fruit orchards (plums, peaches, apricots), grapevines, prickly pears, and grains, the local economy is now based on tourism, and many traditional agricultural and maritime practices have been abandoned. In this study, we aimed to evaluate the state of traditional ecological knowledge (TEK) concerning the use of wild and cultivated plants and fungi for human health, food, maritime, and agricultural purposes on the islands of Levanzo, Favignana, and Marettimo and compare present-day practices with those documented in the past. Methods In-depth semi-structured interviews …
Atlas of the Baltic languages: plant names of Slavonic origin
2015
Atlas of the Baltic Languages: Plant Names of Slavonic Origin The article investigates Slavonic-derived plant names in dialects of the two surviving Baltic languages – Latvian and Lithuanian. Historically, these Slavonisms were originally adopted by small-scale regional dialects, which are now disappearing. In 2009, a pilot study for the Atlas of the Baltic Languages was published. It comprised 12 geo-linguistic maps with Latvian, Lithuanian and English commentaries. 2012 saw the publication, in CD format, of the Atlas ’s first volume: Lexis 1: Flora . The material analysed concerns names for: (1) wild plants, e.g., cornflower, nettle, waybread, milfoil, dandelion, plantain; (2) cultivated …
First record of Tamarix meyeri (Tamaricaceae) for western Europe
2012
Abstract Field investigations and herbaria reference work carried out in Italy and Spain allowed us to identify wild and cultivated plants of Tamarix meyeri, a new species from western Europe. This small tree is characterized by tetramerous, rarely pentamerous flowers and a paralophic disk.
The Monumental Olive Trees as Biocultural Heritage of Mediterranean Landscapes: The Case Study of Sicily
2021
Monumental olive trees, with their longevity and their remarkable size, represent an important information source for the comprehension of the territory where they grow and the human societies that have kept them through time. Across the centuries, olive trees are the only cultivated plants that tell the story of Mediterranean landscapes. The same as stone monuments, these green monuments represent a real Mediterranean natural and cultural heritage. The aim of this paper is to discuss the value of monumental trees as “biocultural heritage” elements and the role they play in the interpretation of the historical stratification of the landscape. We present the results of a survey of the most s…
A new species of Kali (Salsoloideae, Chenopodiaceae) from Sicily, supported by molecular analysis
2015
Nomenclatural and taxonomical considerations on Kali , a controversial genus recently segregated from the polyphyletic Salsola s. lat. ( Chenopodiaceae ), are provided. The Kali group includes annual plants with leaves ending in a spine and lacking hypodermis, having also a cortex alternate to longitudinal chlorenchymatous striae. The species belonging to this genus mainly have a paleotemperate distribution (Europe, Asia and North Africa), occurring as aliens in North America, Australia and South Africa. A new species collected on Mt. Etna (Sicily), and closely related to K. australe , is described and illustrated as K. basalticum Its morphological and molecular features, karyology (2n=54),…
