A morphological divergence study among the twenty genotypes based on nine yield and yield contributing characters through the D2 statistic indicated the presence of substantial diversity by forming clusters with a wide range of inter-cluster distances. The soybean genotypes under investigation were divided into five clusters. Cluster I had the most genotypes, with 10, followed by clusters III and V, each with five and three genotypes. The relative divergence indicates how much each cluster varies from the others. Cluster I and Cluster III have the most significant order of divergence, followed by Cluster III and Cluster IV. The results revealed that the parents in these clusters are genetically heterogeneous. It's possible that a hybridization program obtained a significant heterotic response. Clusters I and II found the minimum inter-cluster distances, indicating limited genetic diversity. Cluster III had the maximum seed yield per plant cluster value. Individual performance was highest for the genotypes BINAsoybean-3, BINAsoybean-2, and Shohag for the trait seed yield per plant.

Citrullus colocynthis (L.). Schrad, is a member of the botanical family of Cucurbitaceae and is commonly called coloquinte or "desert gourd", Handhal (Arabic) or Alkad (Tamahaq). This plant is known for its high oil content, it is a source of biodiesel and a real substitute for conventional diesel. Biodiesel is defined as a chemical alteration of vegetable oil to match the characteristics of the engine. The transesterification reaction is the most common method for converting coloquinte oil into esters and glycerol. The purpose of this communication is to draw attention to the biodiesel produced by coloquinte, which has been widely described in the literature.

Ectomyelois ceratoniae Z is one of the most dangerous insects in the world and Algerian phoeniciculture. The survival of this insect is based on the search for the appropriate dates varieties to its nutritional needs. In this paper, an experimental study was performed to determine these nutritional needs and the mechanisms to obtain them from dates. In this study, three susceptible varieties to the moth attack were chosen, the healthy and infested dates were separated to calculate on the one hand the attack rate and to carry out the qualitative analyzes. The results showed that the moth selects the appropriate dates to lay its eggs and feed the larvae based on the consistency of the dates and their high sucrose content. The content of the sucrose is reduced in attacked dates, resulting from their consumption after the enzymatic degradation by Invertase for the synthesis of simpler sugars (fructose and glucose) to be easily used by the larvae. The more the medium is very acidic (infested dates), the more the degradation of sucrose is important. The total sugar is also necessary to produce sufficient energy for the biological activities of the moth (growth).The use of these organic elements by the larvae leads to a reduction in the weight of the date and increases its fragility.

Home gardens are subsistent agricultural production systems consisting of diverse crop plants which are easily accessible and adjacent to homesteads. They sustainably contribute to livelihoods in developing countries. Regarding the modernization in tropical Africa, there are changes in plant composition of urbanizing areas like Tubah Sub-Division, North West Region, Cameroon while the useful plant diversity in home gardens are poorly or not documented. This study aims to assess the diversity of useful plant species and identify key factors that influence diversity. 120 selected home gardens from Tubah Sub-Division were surveyed using two complementary field sampling approaches: interaction with selected households head through the use of structured questionnaires on garden plants and direct field observation. To assess plant abundance, the entire home garden was considered as a sample plot for tree, shrub, climber and epiphytic plant species while for herbaceous species, five quadrats of 1 m2 were used to count each species. A total of 133 useful plant species belonging to 108 genera and 47 families were recorded, with the number of species varying among the villages. The dominating families were Solanaceae, Fabaceae and Asteraceae. Age of household head and age of home garden were the key factors which significantly influenced the plant diversity. As home gardens in Tubah Sub-Division consist of diverse garden plants which are of great importance, we suggest that home gardening should be promoted, through education and extension services. This study should also be extended to other parts of the North West Region.

This paper describes a comparative study of tow chiral separations of (RS)‐Propranolol racemate by HPLC using α-Glycoprotein (AGP) and β-Cyclodextrin (BCD) Stationary Phases. For the AGP separation, the column size was (150 mm X4 mm X 5 μm), the mobile phase composed of Propanol-2 and Ammonium acetate (0.5:99.5 v/v), at a flow rate of 0.9 mL/min and the detection by ultraviolet absorption at 225 nm. For the BCD separation, the column size was (250 mm X4 mm X 5 μm), the mobile phase composed of Acetonitrile: Ethanol: Acetic acid: Triethylamine (960: 40: 4: 3 v/v/v/v), at a flow rate of 1 mL/min and the detection by ultraviolet absorption at 225 nm. The retention time of S-Propranolol and R-Propranolol with AGP separation was respectively: 7.25 min and 11.82 min while with the BCD separation 16.18 min and 18.50 min respectively. The racemate contains 50.46 % of S-Propranolol and 49.53 % of R-Propranolol with AGP separation while with BCD separation, it contains 50.43 %/49.57 %. There is a similarity between the enantiomeric purity values and the enantiomeric excess values of tow separations, but the separation with AGP stationary phase is faster than with the BCD stationary phase. For a selective β-blocking use, it could be very interesting to encourage its production in its form enantiomerically pure wich is the S-enantiomer.

The cowpea is exogenous crop introduced into the extreme south of Algeria from Niger; it has been cultivated and preserved by the farmers of Hoggar (Tamanrasset, Algeria). Our study was carried out to survey, collect identify and document the uses of cowpea landraces at the level of this arid region. To this end, missions have been organized on this traditional agriculture, in order to collect accessions as possible and to provide information on cultural practices and traditional know-how related to this culture. The study is part of the more than ethnobotanical prospection of the landraces encountered during our investigation in ten communes of the wilaya of Tamanrasset located the Hoggar. Hoover, a semi-structured questionnaire was elaborated taking into account the objectives expected. It concerns the farmer, ethnobotanical, agronomic information’s and the economic management of the farm (the farmer, his farm and the technical itineraries adopted). In fact, (50) farmers were interviewed and a sampling was carried out in each commune surveyed, and eighteen (18) local cowpea landraces were harvested through outings that were organized during year 2018. This study showed that among the farmers interviewed, 70.02% were men and 29.07% were women. The farmers cultivate cowpea on small areas, its production is used only for self-consumption and a small marketed in the villages where the plant is cultivated, three main parts are used by the farmers surveyed: seeds, green pods and hay. After the harvest, the rest of the plant (leaves and stems) are used to feed livestock (sheep and cattle). Cowpea cultivation is in danger of disappearing, according to the majority of the farmers surveyed, diseases and insect attacks are low (32%).In addition, low rainfall, electricity and lack of labor during manual harvesting seem to be the main production constraints reported by the farmers surveyed. While farmers are satisfied with the yields they have obtained. The pods and seeds collected are also characterized by quantitative traits such as Seed thickness (ST), Seed diameter (SD), and Weight of 100 seeds (WHS), pod diameter (PD), number of eggs by pod (CIP), number of seeds by pod, (NSP). Also, by qualitative characters such Seed color (CG), Eye color (CE), Seed form (F), Seed texture (T), were considered. The results showed that the diameter and thickness of pods (PD and PT) varies from 7.5 to 20 cm and 0.3 to 0.8 cm successively.

The polyherbal formulation known as ELNA consists of Moringa oleifera, Crateva religiosa and Curcuma longa. It ethnomedicinal properties include; analgesic, inflammation, cardiac diseases, bacterial infection and immune suppressed diseases. The aim of this study was to evaluate the ex-vitro non-enzymatic anti-oxidant, biosafety, analgesic and anti-inflammatory effect of aqueous ELNA polyherbal extract. Ex-vitro anti-oxidant study was investigated in ELNA extract using standard radical scavenging protocol. Biosafety effect of ELNA extract was understudied with the aid of Locke method. Acetic acid-induced peripheral pain, hot plate-induced central pain and egg albumin-induced inflammatory models were investigated. Results from this study exhibited the scavenging effect of ELNA extract against 1, 1-diphenyl-2-picryhydroxyl with significant increase in concentration dependent manner. Acute toxicity study of the aqueous extract of ELNA elicited less or no toxic effect, with no mortality and side effect above LD50>5000 mg/kg body weight. Aqueous ELNA extract displayed no damaging effect of the sub-chronic toxicity study administered for 28 days, exhibited no significant difference (p= 0.05) in the organ and body weight. No significant different in the haematological parameters excluding 400 mg/kg with slight significant (p<0.05) increase in platelet count. Graded doses of the extract at 400, 800 and 1200 mg/kg body weight exhibited significant (p<0.05) reduction in central and peripheral pain. Significant reduction in paw edema volume. Specifically at higher doses, the extract showed an effective activities against the selected study. In conclusion, this study validated the ethnomedicianl evidence of ELNA aqueous extract of the formulation.

In conclusion, this study validated the ethnomedicianl evidence of ELNA aqueous extract of the formulation.","PeriodicalId":431221,"journal":{"name":"Algerian Journal of Biosciences","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121513614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The present study was based on the observations and captures of reptiles in the Northern Algerian Sahara (2011-2013). Thirty homogeneous stations, representing the principal landscape units and ecosystems, were investigated. The studied ecosystems were the erg (sand dunes), saline areas (Chott, Sebkha), reg, palm groves, and urban sites. We have identified 30 species (20 Saurians, 9 Ophidians and one Testudines). The inventory concerns 2 orders (Testudines and Squamata), 12 families and 22 genera. Among the identified species, seven were protected in Algeria, 5 species (Tarentola deserti, Tarentola neglecta, Trapelus tournevillei, Hemorrhois algirus and Natrix Maura) are endemic according to U.I.C.N. The number of species in the different IUCN Red List Categories shows that 28 are assessed as Least Concern, one specie is considered to be Data Deficient (Scincopus fasciatus) and One species is listed as near threatened (Uromastix acanthinurus). The species distribution according to the habitat types showed that he erg was the most populated ecosystem with the highest number of captured individuals (403 individuals). The highest species richness was noticed in the palm groves with 19 species as well as the Shannon diversity index (3.34). The evenness is at its highest in the saline and the urban site with 0.89 and 0.81. The correspondence factorial analysis showed that some species were characteristic of habitats such as Tarentola neglecta and T. deserti which are detected as a specific species of the urban sites and the palm groves, while Scincus was a specific species of the Erg. The generalized linear model showed that the geographic coordinates (altitude, longitude and latitude), the spatio-temporal factors (habitat type; climatic period) and human pressure have significant effects on the abundance variation of the studied reptiles.

The phenomenon of albinism is repeated several times in sparrows, where as of december 8, 2018, a case of a male sparrow was observed in the city of Metlili (Ghardaïa - South Algeria), with a remarkably whitish color. Another observation of three (03) cases of total albinism in young males observed in Algiers in June 2007, precisely in Bir Khadem (Algiers - Northern Algeria).
