        D. Hassanpanah H. Hassanabadi
        In this research potato cultivars including Savalan, Agria and Kaiser and its promising clones (397009-3, 397008-10 and 397009-7) were examined in three irrigation regimes in a split plot design based on randomized complete blok design with three replications in Ardabil More
        In this research potato cultivars including Savalan, Agria and Kaiser and its promising clones (397009-3, 397008-10 and 397009-7) were examined in three irrigation regimes in a split plot design based on randomized complete blok design with three replications in Ardabil Agriculture and Natural Resources Research Station during 2008 and 2009. Irrigation treatments (irrigation rate of 50, 75 and 100 percent of water required) were assigned to main plots and promising clones and cultivars to sub-plot. Analysis of variance showed that there were significant differences among irrigation levels and cultivars in for total and marketable tuber yield, tuber number, tuber weight per plant, years and years × cultivars interaction of total tuber yield, irrigation levels × cultivars interaction in all traits except total tuber weight per plant and main stem number per plant. All of the clones and cultivars at 100 percent required water, 397009-3, 397008-10 and 397009-7 clones, Savalan and Kaiser cultivars at 75 percent required water and 397009-3, 397008-10 clones and Savalan cultivar at 50 percent required water produced higher marketable tuber yields. Clone No. 397008-10 produced high marketable tuber number and tuber weight per plant in all of irrigation levels. Clones 397008-10 and 397009-3 and Savalan were selected under mild and severe water deficit conditions, and Agria as susceptible to water deficit. Manuscript profile

        Tree growth has a great ecological and economic importance and stem analysis is one of the reliable and widely used methods which is used to study the growth of different attributes of the trees. In the present study, we evaluated diameter, basal area, and height and volume growth of two fast growing species (namely Populus deltoides and Taxodium distichum). After falling down the trees, 5 centimeter thick disks at 2 meter intervals were collected and transported to the laboratory. The thickness of the annual rings was measured in two perpendicular directions up to1millimeter precision. The results showed that the highest value of the current growth of diameter of Populus deltoides and Taxodium distichum occurred in 4 and 6 year ages, respectively, equal to 1.5 and 5.4 cm and the highest value of the current basal area growth of Populus deltoides and Taxodium distichum occurred in 9 and 10 year ages, respectively, equal to 0.1 and 0.14 square meters. Furthermore, the highest value of the current growth of height of Populus deltoides and Taxodium distichum occurred in 6 and 9 year ages, respectively, with value of 1.3 m 3.1 m and the highest value of the current growth in the volume of Populus deltoides and Taxodium distichum occurred in 8 and 12 year ages, with a value of 0.094 and 0.1 cubic meters, respectively. Finally, there would be concluded that both of these species in such sites can meet the environmental needs such as green spaces as well as economic goals such as commercial wood product.

        Background & Objectives: Staphylococcus epidermidis is one of the main causes of urinary tract infections and second cause of respiratory infections in human. The aim of this study was genotyping S. epidermidis strains isolated from nosocomial infections and detection of genetic clones using Multilocus Sequence Typing (MLST) method. Materials & Methods: In this cross-sectional study, 16 S. epidermidis isolates were selected and PCR products from amplification of seven housekeeping genes were sequenced. The nucleotide sequences of each gene in each isolate were analyzed in the MLST database and, besides identifying different clones, gene - specific alleles in each sequence types (ST) were determined. Results: A total of 3 clones including ST22, ST88 and ST153 were identified from 16 isolates, which was classified into two gene clusters of A and B. ST22 clone with a frequency of 50%, ST88 with 31.25% and ST153 with 18.75% were identified. The most dominant S. epidermidis clone isolated in 16 isolates is ST22. Conclusion: Dendrogram analysis of the isolates showed the homology of all isolates to alleles previously reported. Furthermore, our results suggest the genetic diversity of the isolates.

        Background & Objectives: Acinetobacter baumannii is a Gram-negative coccobacillus that is widely distributed in nature and considered as one of the important causes of hospital infections. The present study was conducted to genotype Acinetobacter baumannii strains isolated from blood infections using Multi Locus Sequence Typing (MLST) method. Materials & Methods: A total of 36 Acinetobacter baumannii strains were isolated from blood infection samples collected from Baqiatalah and Payambaran hospitals, Tehran, Iran. The PCR products obtained from amplification of seven housekeeping genes were sequenced. The nucleotide sequences of each gene in each isolate were queried against the reference sequence in the MLST database. In addition to characterization of the alleles specific to each gene, thesequence types (ST) of all isolates were determined. Results: A total of 5 clones including ST25, ST136, ST307, ST327, and ST328 were identified in 36 isolates. ST of 2 isolates were not identified in MLST database. The identified STs were placed into 5 genetic clusters including A, B, C, D, and E. Conclusion: Identifying an acceptable level of genetic diversity among the isolates using MLST technique shows that this method is useful for studying and typing of Acinetobacter baumannii isolates. Therefore, it is possible to cluster isolates with diverse origins in different groups. Manuscript profile
