Strategies of seed germination in some medicinal and oleaginous plants

The aims of this investigation were to study the strategies of germination behaviors and metabolic responses of two shrubs Simmondsia chinensis; Moringa oleifera and one tree Cassia fistula)seeds affected by single factor as salinity sodium adsorption ratio and temperature or / and their combinations. Also the present work was to run a comparative study between three species of different ecological affiliations. Comparison is mainly concerned with the means of adjustments during the process of germination to major ecological stresses mentioned.
