Vegetation Composition Related to Environmental Factors along the International Highway-West Alexandria, Egypt

The present study aimed to characterize the ecological features of the vegetation along theinternational coastal road from El-Ajami to Ras El-Hekma, West Alexandria, Egypt. The clusteranalysis of 60 stands was performed using the Community Analysis Package program and Detrended Correspondence Analysis (DCA). Canonical Correspondence Analysis (CCA) was used to identify the ecological relationships between the vegetation and the environment along the roadside. The total number of the recorded p...

Vegetation and Species Diversity in the Northern Sector of Eastern Desert, Egypt

The study aims to assess the vegetation and plant diversity in relation to edaphic factors at three sites (Cairo- Suez, Ain Sokhnia-Makattam desert roads and Wadi Hagul) in northern sector of Eastern Desert. The results revealed that northern sector of Eastern Desert (The Galalah Desert) harbors had 95 species (36 annuals, two biennial and 57 perennials) with high taxonomic diversity (species/genera = 1.17 and genera/families = 3.12). The largest families were Asteraceae comprising 22 species...

Seed dormancy in palms

Seed dormancy in palms, date palm inclusive have continued to be challenging especially when cultivating through seeds. This study evaluated different methods of breaking dormancy and seed germination rate in P. dactylifera. Using Completely Randomize Design, two varieties of P. dactylifera were treated with three treatments comprising sulphuric acid, hot water, cold water and control. Result showed that all the three treatments significantly (p < 0.05) affect the germination rate and ear...

Enhancing Food Supply Through Genetic Engineering

ABSTRACTGreat progress has been made over the past decades with respect to the application of genetic engineering to increase food supply and to generate nutritionally improved food crops. The role of genetically modified (GM) crops for food security is the subject of public controversy. Genetically engineered crops could contribute to food production increase and higher food availability. They also impact on food quality and nutrient composition. This work discusses the challenges of food in...

Biological Control Using Trichoderma harzianum against Penicillium purpurogenum, Causal Agent of White Yam Tuber (Dioscorea rotundata Poir) Rb

In vitro assessment of biological control of Trichoderma harzianum against Penicillium purpurogenum isolated from rotted yam tubers (Dioscorea rotundata Poir) in storage was conducted in the Advanced Plant Pathology Laboratory, Federal University of Agriculture, Makurdi, Nigeria. The antagonist and the pathogen were paired in dual culture at different times (antagonist same time with the pathogen, 2 days before the inoculation of the pathogen and 2 days after the inoculati...

Influence of Pedological Regimes on Plants Distribution in a Lacustrine Wetland in Uyo, Akwa Ibom State, Nigeria.

 Studies on the influence of pedological regimes on plant distribution in a lacustrine wetland in Uyo, Akwa Ibom State, Nigeria revealed variations in density and frequency of plant species as a function of the soil parameters. A quadrat size of 5m x 5m through systematic sampling was used to sample the vegetation spaced at regular intervals. The vegetation parameters determined were density and frequency. Soil samples were collected at different depths (0 – 15 cm and 15 – 30 cm) and ana...
