The aim of the present study was to examine the influence of photosynthetic pigments composition in Zygophyllum, Tribulus and Fagonia plants in Saudi Arabia. We have selected Zygophyllum, Tribulus and Fagonia genera of Zygophyllacea family were collected from several geographical regions in Saudi Arabia. We have performed the pigment determination and total protein tests. It has been shown from our experiment that, leaves of studied plants were greatly varied in their photosynthetic pigments between different genera and within the same species from different location.

The aim of the present study deals with the pollen morphology of Zygophyllum simplex, Zygophyllum migahidii, Tribulus terrestris, Tribulus macropterus, Fagonia glutinosa, Fagonia indica in the species of Saudi Arabia. In this study, we have performed the scanning electron microscopy method for the analysis of pollen grains by herbarium species. Pollen grains were squashed and mounted under the microscope. The results of this study specifies the observation of pollen grains in all the species collected from Saudi Arabia region.

Synthetic seed technology is an alternative to traditional micropropagation for production and delivery of cloned plantlets. Synthetic seeds were produced by encapsulating nodal segments of C. angustifolia in calcium alginate gel. 3% (w/v) sodium alginate and 100 mM CaCl2 · 2H2O were found most suitable for encapsulation of nodal segments.

Many plant species may be used for the production of herbal preparationscontaining phytochemicals with significant anti-oxidant and antiinflammatorycapacities and health benefits. Citrullus Colocynthis spp is among the most known for the medical plants. The aim of our approach was to study the morphological and taxonomical parameters for Citrullus Colocynthis in the Saudi Arabia.
