Biological activities of species in the genus Tulbaghia: A review
Since time immemorial, plants have been used by several communities to treat a large number of diseases. Numerous studies on the pharmacology of medicinal plants have been done. Medicinal plants constitute a potential source for the production of new medicines and may complement conventional antimicrobials and probably decrease health costs. Phytochemical compounds in plants are known to be biologically active aiding,...

Selection of okra parents based on performance and genetic divergence
A total of 200 okra accessions with wide variability and a potential for genetic improvement were stored in the Vegetables Germplasm Bank of the Federal University of Viçosa (UFV-BGH) in Viçosa, Minas Gerais State, Brazil. The objective of this work was to select parents by genetic divergence and behavior per se in 70 okra accessions from the BGH-UFV by quantitative and qualitative descriptors of economic...

Evaluation of genetic divergence and phylogenetic relationship using sequence-tagged microsatellite (STMS) sequences in Chickpea (Cicer arietinum L.) genotypes
The current investigation was carried out to analyse the genetic diversity estimates between 125 chickpea genotypes using sequence-tagged microsatellite (STMS) markers. Thirty one STMS primers generated a total of 153 loci (an average of 4.94 loci per primer) out of which 129 loci were found to be polymorphic and 24 loci were monomorphic. The value of PIC varied from 0.128 to 0.783 while the resolving power varied from...

Genetic diversity of bitter and sweet African bush mango trees (Irvingia spp., Irvingiaceae) in West and Central Africa
Economically important food tree species in sub-Saharan Africa should be domesticated to enhance their production within agro forestry systems. The African bush mango trees (Irvingia species) are highly preserved and integrated in agro forestry systems in tropical Africa. However, the taxonomic debate related to the species or varietal status of the bitter and sweet fruited African bush mango trees hinders their...

Glycerine associated molecules with herbicide for controlling Adenocalymma peregrinum in cultivated pastures
The weed Adenocalymma peregrinum that is popularly known in Brazil as “ciganinha”, belongs to the family Bignoniaceae. The only way to control this plant species in crop fields is by the application of herbicides on the stump or directly on the stem. The present study aimed to analyze the effect of glycerine in controlling A. peregrinum (MIERS) L.G.Lohmann when applied on the stem. The glycerin used as a...

Techno-economic analysis of fuel ethanol production from cassava in Africa: The case of Tanzania
The abundance of low-cost feedstock is of great importance for reinforcing industrialization of bioethanol as a sustainable source of eco-friendly energy. This paper describes improved techniques that increase the root productivity of cassava (Manihot esculenta) and its conversion to bioethanol. A variety of models and analytical approaches were used to choose the best technologies, considering various levels of...

Stimulatory activity of four green freshwater sponges on aquatic mycotal communities
The influence of the four species of green sponges (Ephydatia muelleri, Heteromeyenia stepanowii, Spongilla fluviatilis, and Spongilla lacustris) on the occurrence of aquatic mycotal species in the water of three four water bodies of different trophy was investigated in this study. Seeds and snake exuviae were used as baits. For the measurement of the primary and extracellular production by symbiotic algae of green...
