Prosopis cineraria is a native species in the south of Iran and it include of compatible species in this area. This species contains has been a wide distribution but discrete in the past, but it's limited regions in now. This research done in investigating possibility of plantation development for Mesquite (Prosopis cineraria) in Rahmatabad watershed of Rigan county, the East Kerman province. The aim of this study was to site location and identify suitable land for development and implementation of the ecological requirements of the species, according to the ecological characteristics of the study area in the East of the province. For this purpose, the method of multi-criteria evaluation has been based on Analytical Hierarchy Process. During this process were identified the natural characteristics and specific requirements of Mesquite and then calculate the weight of each characteristic by weighted analytic hierarchy process (AHP), the final map of the habitat area was prepared for the development of Mesquite trees. The results showed that the total area of 37286 ha, about 3423 ha of the land where good capability, 13521 ha the average capability, 17343 ha low capability and 2999 ha for the plantation of Mesquite has without capability. Using the results of this study can recognized prone areas of Mesquite using the MCE method in GIS and for the plantation of this species in places with good habitat can be planned in the future.

The aim of this study was to investigate the antimicrobial activity of Prosopis farcta L. and Datura stramonium L. extracts on Salmonella thyphimurium isolated from poultry in Zabol. The P. farcta and D. stramonium were collected from Collection of medicinal plants, Institute of Agricultural Research at University of Zabol. Strains of Salmonella thyphimurium were isolated from poultry droppings. Antibiotic resistance pattern was determined by Kirby Bauer method. Finally, the minimum inhibitory concentration (MIC) and minimum bactericide concentration (MBC) were determined by microdilution method. The results of this study showed that the lowest inhibitory concentration of Datura extract against Salmonella typhimurium was 3.1 ppm; While the minimum inhibitory concentration for Prosopis extract was 6.5 ppm. Also, the minimum bactericidal concentration of Datura extract was 6.25 and Prosopis extract was 12.5. The results of this study showed that Datura extract was more effective in inhibiting Salmonella bacteria than Prosopis extract. Evaluation of Pearson correlation coefficient between total phenol content, total flavonoids and MIC, and MBC showed an inverse relationship between these parameters. So that the Datura extract, which contained higher total phenol, and total flavonoid, had lower MIC and MBC and therefore was more effective in inhibiting bacteria. The results of our experiments showed that Datura and Prosopis extracts have good antimicrobial effects and can be used to treat infections caused by Salmonella typhimurium in poultry.

Plants are valuable sources of different antioxidant and antimicrobial compounds. The composition and structure of the functional groups of essential oils and extracts play an important role in their antioxidant and antimicrobial activity. Prosopis farcta is a spice of Leguminosae family and Mimosoideae subfamily, an aborigine to the dry and semi-dried regions of Asia, Africa and America. In this study, the root extract of Prosopis farcta prepared by the soxhlet extractor and ethanol 70% solvent. The extraction yield was estimated at 1.85%. Total phenol and flavonoids compounds were calculated 178.14 ± 0.17 mg Gallic acid/g and 94.33 ± 0.77 mg Quercetin/g, respectively. Phenolic compounds comprised 11.98% of the total chemical composition of the extract. IC50 for root extract and BHT (synthetic antioxidant) was determined 2.45 μg/ml and 1.98 μg/ml, respectively. In the β-carotene-linoleic acid system, the average antioxidant activity reported 39.25% for root extract and 57.13% for the BHT. Among 250, 500 and 1000 ppm concentrations of the extract, 1000 ppm showed the best antioxidant effect in soybean oil for 12 days storage at 50°C. Staphylococcus aureus (with MIC 200 µg/ml and MBC 350 µg/ml) showed the most sensitivity in comparison with the two gram-negative bacteria, Salmonella Typhimurium and Escherichia coli. The results of this study showed that the hydro-ethanolic root extract of Prosopis farcta had suitable antimicrobial and antioxidant activity.

Effect of explants source, plant growth regulator and NaCl on organogenesis and proline accumulation in prosopis Kolziana, salt tolerant species, were studied. Meristem, young leaf, and cotyledon separated from in vitro seedling. Then explants were cultured on MS medium supplement with different plant growth regulators. Multiple shoot regeneration was observed in meristem explants. In contrast leaf callus did not produce any shoot and root. The best treatment for shoot regeneration was MS Medium containing 1 mgl-1 6-benzylaminopurine and 0.1 mgl-1 naphtalenacetic acid. Auxins promoted callus and root regeneration. In contrast cytokinin hormones induced shoot formation. Effect of different concentrations of NaCl (2, 4, 6, 8, 10 gl-1) on organogenesis and proline accumulation were investigated. The result showed salt stress tends to decrease of organogenesis. But it had less effect on callus induction. Although, high content of NaCl inhibited both callusing and shoot regeneration. Proline content was significantly increased by increasing the NaCl. Increasing the NaCl concentration from 8 mgl-1 to 12 mgl-1 did not enhance proline content. It is suggested proline had an important role on salt resistance in this species.
