Influence of watering regime and mycorrhizae inoculations on the physiology and early growth of Acacia senegal (L.) Wild.
Acacia senegal is endowed with features that give it potentials for ecosystem stabilization, anti-desertification and for production of high quality gum-Arabic. However, the natural population which is becoming low has been traced to poor seed germination and seedling survival. The influence of watering regime and mycorrhiza inoculation on some physiological parameters and early growth of A....

High and low pressure gene gun devices give similar transformation efficiencies in maize calluses
Maize (Zea mays) is a major food crop of the world. Biotechnology plays an important role in plant genetic improvement, particularly for the introduction of novel traits in order to improve agronomic performance, medical and industrial applications and food quality. Particle bombardment is a rapid and simple method that enables the generation of events and affords genes expression studies. Nonetheless, an...

Effects of leaf harvest and season on the fruit yield of summer squash genotypes in Madagascar
Summer squash (Cucurbita pepo L.) is one of the most popular vegetables in Madagascar, where it is grown for both leaves and fruit. Previous breeding efforts concentrated solely on high fruit yield. In recent years the demand for varieties that can produce edible fresh leaves and high fruits yield has increased. Our objective in this study was to evaluate the effects of leaf harvest and season on...

Genetic diversity and characterization of African eggplant germplasm collection
Genetic diversity among 70 “scarlet eggplant” (Solanum aethiopicum L.) entries from different geographical origins was assessed. Entries were firstly evaluated for the main morphologic traits and chlorogenic acid content. Standard statistics and multivariate analyses were utilized to assess the phenotypic diversity and grouping the entries. In addition, amplified fragment length...

A comparative study of morphological and molecular diversity in Ethiopian lentil (Lens culinaris Medikus) landraces
Genetic diversity assessment with different methods and their comparison could provide complementary information for improvement and conservation programs. However, such information is not available for Ethiopian lentil landraces. To fill this gap, nine morphological traits and four ISSR primers were used on seventy Ethiopian lentil landrace accessions to study morphological and genetic diversity among the...

Assessment of traditional medicinal plants in Endrta District, South-eastern Tigray, Northern Ethiopia
Ethnobotanical data were collected between September and December, 2009 on six field trips to investigate medicinal knowledge and application of medicinal plants in Endrta Wereda (the lowest administrative unit in Ethiopia), South-eastern Tigray, Northern Ethiopia. Semi-structured interviews, observation and guided field walks with informants were employed to obtain ethnobotanical data. A total of 35...

Comparative study on physicochemical variation for different samples of Cassia grandis Linn. leaves
The present study is intended primarily to confirm changes with respect to quality of the drug. The variability in proper production unit, supply unit, methodology of collection and storage conditions were used to change the crude herbal drugs. The lack of knowledge of proper methodology, availability and more demands of herbal drugs for better treatment are promoting the practices of adulteration and...

Seed coating of safflower (Carthamus tinctorius L.) in order to delay germination
The idea tested was the restriction of water uptake as a means of influencing the germination rate of the coated seed. This led to the choice of an acrylic plastic polymer to be used as coating material. Assembled spinning disc equipment was used for coating the seeds. The germination tests of the coated seeds were performed in Petri dishes in a randomized complete blocks design with five replications. With...
