The study included the gross general morphological and micromorphological characters, the Pollen grains also studied and the chemical compounds, Ecological and geographical distribution and taxonomic treatment have done.Also botanical key was putted to separate the species. General survey for the Phytogeographical districts where the taxa spread in, and the result was a large crowds of samples, and new locations of taxa distribution were recorded. The specimens studied, and correct the mistake naming, specimens were identified and reidentified some miss identified specimens in the Iraqi herbaria. A comparative morphological study was undertaken to all plants parts of taxa appeared from habit and duration of taxa to the quantitative and qualitative attributes the members of the vegetative and floral parts included the roots, stems, leaves, stipules, flowering parts and fruiting parts and drew charts diagrams, tables and accompanying with natural images for different morphological characteristics, as well as the field images. This study showed that all species was herbs, shrubs and succulent and semisucculent annual and perinnal, the major taxonomic importance was for flowering parts includeing the specific Inflorescence, installation of a cupped and its regularity on the branches of the plant, glands forms, numbers, presence or lack of appendages, bractes and bracteoles shapes, dimensions and color fruits shape, indumentum and seeds forms, dimension and her surface sculpturing; and the presence or lack of caruncle, as well as the qualities of roots, stems and leaves, and the morphological characteristics of all plant parts mentioned above have a taxonomic importance in identification and separation of the studied taxa. The study of the micromorphological characters of hairs, leaves epidermal cells and the stomatal complex which included anomocytic, paracytic, anisocytic and tetracytic, have a taxonomic importance of supporting the morphological characters in separation and identification of the genus taxa.The pollen grains have a taxonomic importance because their different in shape, dimensions of polar and equatorial view, the wall thickness and their ornamentation. They are mostly of Tricolporate except two species were Hexacolporate, also the differences in their shape in the polar and equatorial view.They were spheroidal, ovoid and oblate - spheroidal in the polar view and oblate, spheroidal, subprolate and oblate - spheroidal in the equatorial view.The ornomentation they were reticulate, microreticulate and foveoate.The chemical study also importance in separation of the genus taxa four compounds Flavonoids diagnosed in all the studing species but different in concentrations, by using HPLC, they are Myriscetin, Quercetin, Kaempferol and Coumarin esculetin and this confirms that there are a common evolutionary link between the species in terms of their chemical properties, which suggests belonging species to the genus Euphorbia.Through field surveys and information installed on the herbarium samples, the taxa where distributed on their growth areas, and maps have been drawn for taxa distribution in the Iraqi natural geographical districts. the species of Euphorbia were distributed in all Iraqi districts especially in LCA, MSU, MRO, and DWD and some species were farmed in gardens and nurseries either to the beauty of their bractes colors or because their acceleration to the environmental changes such as succulent species, As well as wild species were spread in mountainous areas, oak, nuts forests, in orchards, cultivated fields, flat plains and desert areas in loam soils, clay, gravel, and sand. Through this study some new taxa where founded in Iraq and they are E. cyparissias Kunth ; E. maculata L. ; E. serpens L. ; E. tirucalli L., and this study suggests to recorded them for the first time in Iraq.

The four laboratory experiments carried out to measure less inhibitory concentration MIC in the growth and the number of bacteria Azotobacter and fixation of atmospheric nitrogen and produce GA3 from bacteria. Fifth experiment pot experiment to study the effect of two types of bacteria Azotobacter and interference with water drainage in the growth and yield plant wheat (Triticum aestevium L.) type (Aba 99).Isolate and diagnose the bacteria Azotobacter : The screening showed and diagnostic results that 11 isolation is a subsidiary of the type A.chroococcum, and 5 isolates belonging to the sensitization A.vinelandii.The isolates (A10, A2, A6, A8) was chosen from A.chroococcum and (A9, A5, A16, A14) was chosen from A.vinelandii was chosen as local isolate used in laboratory experiments based on the measurement of the soil salinity isolated ones, and selected isolates A10, A8, A5, A14 local isolate used as biofertility to the experience of pots because of their ability to nitrogen fixation by measuring the amount of nitrogen fixation in the third experiments. Laboratory experiments : The first and second experiment : Two trials were conducted Laboratory by using randomized complete block design (RCBD), each experiment included (120) experimental unit for each lap. Resulted from (8) isolates bacterial and five Trakizmn salt NaCl (0, 1, 3, 5, 7)% and (3) replicates, and incubated for three periods lap (1.3, 6) days to calculate the (MIC) in the growth and cell numbers bacterial. The results showed that the number of bacteria cells A.vinelandii rate increase all isolates A.chroococcum regardless of the concentrations of NaCl and extended incubation. Although isolates (A16, A14) isolated from soil salty surpassed isolates (A9, A5) isolated from soil is salty, and isolates (A8, A6) A.chroococcum of bacteria isolated from soil salty surpassed isolates (A10, A2) isolated from non - saline soil. The highest values of the numbers of bacteria are isolates A8, A16, amounting to (11.13, 11.0) * 104.cfu g - 1 dry soil. The increase in the concentration of NaCl led to a decrease significantly in the growth and the number of bacteria Azotobacter cells as the decline amounted to 17.13%, 45.52%, 59.50%, 76.99% at concentrations of 1%, 3%, 5%, 7%, respectively, and recorded the lowest numbers in the values of focus 7%, reaching 3.80 * 104. Cfu g - 1 dry soil. The growth and numbers of bacteria Azotobacter increased treatment effect when increasing the extended cuddling and all concentrations of NaCl. In a period of one lap on all isolates were grown in 1% NaCl concentration of the MIC for all isolates focus is 1%, while the two lap 3 days, all isolates growing focus recorded (3%, 5%) excluding A16 isolation of bacteria A.vinelandii was able to focus on growth until 7%, so the damper the MIC for this isolation focus is to concentrate 7%, while the rest of the isolates the MIC have 5%, which indicates that this isolation is more resistant to salinity of the isolates.The third experiment : The results showed that the rate of nitrogen fixation bacteria Azotobacter between (0.008 - 0.04%), but an increase in local concentrations led to a decline in moral decline as nitrogen fixation rate of 50.0%, 77.5%, 95.0%, 98.0% at concentrations of 1% salinity, 3%, 5%, 7% respectively.All isolated of bacteria Azotobacter can nitrogen fixation in the all salinity level. although A.chroococcum isolates isolated from non - saline soil surpassed isolates isolated from soil salty and all levels of salinity. Fourth experiment : A laboratory Conducted experiment by using a randomized complete block design (RCBD), included the experiment (12) experimental unit. Resulted from (4) bacterial isolates and three concentration of salt NaCl (0, 3, 5)% to calculate the MIC in the production of bacteria gibbereline Azotobacter. The results showed that the production rate of bacteria gibberline Azotobacter and all isolates ranged from 0.996 - 3.6 mg. L - 1, regardless of the concentration of added NaCl. And increasing salinity levels have led to a reduction in the production of Aljprlin, recorded A8 isolation from A.chroococcum isolated from soil salty higher values in the production of Aljprlin and all levels of salinity Experiemet of pots : The experiment was Carried out in the College of Agriculture, University of Diyala in the soil of a fusion sand using a design full sectors randomized (RCBD) in the winter season of the year (2013 - 2014). The experiment included on (60) experimental unit, resulting from the overlap between the four isolates bacterial treatment compared without the addition of bacterial vaccine and four concentrations of water drainage. The results showed that the addition of the vaccine bacterial gave a significant increase in plant height, dry weights of grouped shoot and root, leaf area, chlorophyll content, holds grains, protein and the concentration of elements of N and decrease the concentration of Na elements, Cl and proline.The addition of the vaccine bacterial and all isolates used led to a significant increase in plant height, dry weights of grouped shoot and root, leaf area, chlorophyll content, holds grains, protein and the concentration of elements of N, and decrease the concentration of Na elements, Cl and the preparation of bacteria Azotobacter in the soil compared to non - bacterial vaccine in addition to all the concentrations of water drainage. The isolates were isolated from soil salty gave an increase in traits higher than isolates isolated from non - saline soil.
