evaluation of genetic diversity is a considerable approach to screen within indigenous rhizobial population for compatible, highly effective strains, which can be further utilized as rhizobial inoculums. genetic diversity of rhizobium isolates from three clover species grown in soil samples of seven different geographical regions in iran was investigated by repetitive extra genomic palindromic ...

There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...

abstract in this study, two wild iranian crocus species (crocus speciosus and crocus cancellathus) were examined using 16 morphological characters and 13 issr primers on 250 and 25 plant samples, respectively. the highest and lowest coefficient of variations were belonged to the thickness of the petals (71.25%) and the leaf length (15.08%), respectively. cluster analysis based on morphological ...

Genetic diversity between fifteen commercial cultivars of rose were evaluated, using Ten decamer primers (A-J). All primers detected polymorphism among the cultivars. In total, 126 bands were produced, 73 of which were polymorphic. Primers E and F produced the highest, while primer H produced the lowest number of bands. The percentage of polymorphic bands ranged from 37% to 81% with an average ...

To validate the credibility of diversity evaluation metrics, a number of methods that “evaluate evaluation metrics” are adopted in diversified search evaluation studies, such as Kendall’s τ , Discriminative Power, and the Intuitiveness Test. These methods have been widely adopted and have aided us in gaining much insight into the effectiveness of evaluation metrics. However, they also follow ce...

There have been many theoretical and experimental investigations on polarization diversity reception characteristics at base stations. The diversity gain was evaluated based on the distribution of the instantaneous received power in these investigations. The mainstream mobile communication systems are shifting to standardized IMT-2000 systems and the W-CDMA system is one of them. The effect usi...

introduction: the scientific, technological and economic development of a society is closely related to its public health. therefore; improvement of health service quality along with increasing the number of health facilities is one of the main concerns of health care authorities in developed countries. this study was designed to compare accreditation models of health care organizations in euro...
