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

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

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

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

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
