To investigate the influence of salinity and calcium (Ca) on some properties of Plantago ovata, a pot factorialexperiment based on randomized complete block design with three replicates was conducted in Jiroft, south of KermanProvince, Iran. Three salinity levels of 0, 100 and 200 mM NaCl and Ca levels of 0, 5 and 10 mM Calcium nitrate wereapplied as the first and second factors, respectively. ...

In order to analyze variation and find an efficient selection approach, we used crossing results between two wheat cultivars, Azar2 and 87-Zhong291. F3 plants (374 lines) and four check cultivars planted in the form of augmented experiment. For germination, seeds were irrigated once. After using multiple statistics methods such as cluster analysis, 79 different lines were selected and used for ...

The past growth of the central black hole ~BH! might have enhanced the density of cold dark matter halo particles at the galactic center. We compute this effect in realistic growth models of the present (223) 310M ( BH from a low-mass seed BH, with special attention to dynamical modeling in a realistic galaxy environment with merger and orbital decay of a seed BH formed generally outside the ex...

The narrow genetic variation of bread wheat is one of the limitations to improve it for drought-tolerance. The research carried out to study the responses of different genotypes and traits to imposed moisture stress. The plant material comprised of 10 Aegilops tauschii accessions as well as a tolerant (BW2) and a susceptible (BW1) bread wheat cultivar. To assess the root and shoot-traits, two s...

In order to evaluate the growth indices and effective morphological and physiological traits of spring wheat (Triticum aestivum L.) using the multivariate statistical method, an experiment was conducted on the basis of randomized complete block design with three replications in Meshkin Shahr, Ardabil province in 2007. During and at the end of the growth season some physiological and morphologic...
