2018 | الكلمات المفتاحية Moringa, nutritional value, medicinal uses, mineral elements, SSR, diversity,
Nutritional, chemical and molecular characterization of Moringa oleifera and Moringa peregrina genotypes
This work aimed to characterise _Moringa oleifera_ (Mo) and _Moringa peregrina_ (Mp), grown in Saudi Arabia, based on nutritional and molecular markers. Seven genotypes per species were evaluated using 1-year-old trees. The nutritional characterisation included chlorophyll, protein, macronutrients, micronutrients, and heavy metals. Simple sequence repeat (SSR) was applied using nine primers for genetic characterisation. Significant differences in nutritional content were ... إقراء المزيد

Morphological and genetic diversity of Moringa oleifera and Moringa peregrina genotypes
This study aimed to assess the diversity of _Moringa oleifera_ and _Moringa peregrina_ in Saudi Arabia. Seven genotypes per species were characterized morphologically using 14 morphological characteristics and genetically using 10 ISSR primers. The studied genotypes were classified according to each characterization, and the correlation between morphological and genetic diversity was investigated. _M. oleifera_ genotypes were distinguished by long, thick ... إقراء المزيد

Essential factors for in vitro regeneration of rose and a protocol for plant regeneration from leaves
_In vitro_ propagation of _Rosa hybrida_, L. cv. ‘Eiffel Tower’ was improved by the addition of thidiazuron (TDZ) and silver nitrate (AgNo3) to the culture medium. The combination of auxin and cytokinins was indispensable for inducing response from leaf discs. Maintaining cultures under dark was better than light for callus formation and quality. The source of explants was vital in ... إقراء المزيد

2017 | الكلمات المفتاحية Life tree, Moringaceae, Sowing, Temperature,
Evaluation of seed germination and growth characteristics of Moringa oleifera and M. peregrina under laboratory, greenhouse and field conditions
This work aimed to evaluate production of Moringa peregrina and M. oleifera, in the central region of Saudi Arabia. Seed germination using seven temperature regimes in laboratory showed that 20°C is the optimum temperature for both species allowing the germination of 87-90% of cultivated seeds within 5 days, mainly from the fourth to seventh days of sowing. Satisfied germination (80%) ... إقراء المزيد

2017 | الكلمات المفتاحية Desert plants, Abiotic stress, Osmotic potential, Tolerance,
Mechanisms of stress tolerance in some important wild plants grown in the Arabian desert
This work aimed to investigate mechanisms of stress tolerance for various wild plants widely distributed in the desert of central Saudi Arabia. The study included nine permanent herbaceous or sub shrubby species of different families and various morphological characteristics. The studied species were _Anthemis pseudocotula_,_ Citrullus colocynthis_,_ Heliotropium bacciferum_,_ Heliotropium supinum_,_ Plantago coronopus_, _Rhazya stricta_,_ Rumex vesicarius_, _Scorzonera intricata_ and ... إقراء المزيد

2016 | الكلمات المفتاحية Gardening, Landscapimg, Green Surfaces,
Comparative Study on the Design and Landscape of Gardens in Different Regions
This study aimed to compare the design and landscape of Egyptian and Saudi gardens to provide information about similarities and differences, and evaluate them for improvement. Two representative gardens were investigated in each country. The Egyptian gardens were Al-Kawsar and Garaman at Sohag Governorate, and the Saudi ones were Al-Escan and King Khalid at Qassim region. All characteristics related to ... إقراء المزيد

2016 | الكلمات المفتاحية Caraway, Spices, Reclaimed Soil, Organic, Biofertilizer,
Growth, Yield and Seed Quality of Caraway under Chemical, Organic or Biological production in New Reclaimed Soil of Upper Egypt
The study was achieved to investigate the production of caraway (_Carum carvi, L._) in new reclaimed soil using organic and biological fertilizers as alternatives for partial or full replacement of chemical fertilization. Experiments were carried out in new reclaimed soil at the Agriculture Experimental Farm of Sohag University, Egypt during two successive seasons. Twelve fertilization regimes were evaluated for their ... إقراء المزيد

The optimum conditions for quantitative and qualitative flowering in chrysanthemum and the endogenous hormones associated with Flowering
The work aimed to determine the optimum conditions for the production of chrysanthemum flowers all the year, and identify the endogenous hormones associated with flowering. Three factors, including plant age, photoperiod and cultivar, were studied on potted chrysanthemum under fiberglass house conditions. Plants were used 1.5 months after the pruning of mother plants (old plants) or after propagation via terminal ... إقراء المزيد

2015 | الكلمات المفتاحية Trees, Germination, drought, Water Stress, Arid Regions, Irrigation Interval, Seed Treatment,
Assessment of Some Important Tree Species for Production under Arid Zones Conditions
This work aimed to investigate seed germination and growth of five tree species under water stress conditions of arid zones. Two separated experiments were carried out to assess their seed germination and water stress tolerance. The first one studied the effect of four seed treatments, including scarification, soaking in water, soaking in ethanol and control with no treatment, on the ... إقراء المزيد

2015 | الكلمات المفتاحية Chrysanthemum, drought, Irrigation Interval, Fertigation, Arid Zones, Water Stress,
Effects of Irrigation and Method of Fertilization on Growth and Flowering Responses of Potted Chrysanthemum
Influences of irrigation frequency and method of fertilization on the growth and flowering of chrysanthemum grown under restricted root volume were tested. To study the effect of water regime, chrysanthemum cuttings were grown in pots and plants were irrigated regularly at 1, 2, 4 or 8 week intervals during growth period. In another pot experiment, the effect of fertilization method ... إقراء المزيد
