a breeding hexaploid salt tolerant wheat line (ms-81-14) was produced from crossing of an iranian salt tolerant wheat line (1-66-22) with inia cultivar (from cimmyt) at karaj research station in 1991-92 cropping season. the f1 plants were grown at karaj in 1992-93 cropping season, furthermore f2-f6 populations were evaluated under salinity stress conditions (ecsoil&water; = 8-12 ds/m) in isfaha...

In a recent paper of Akhunzhanov and Shatskov the two-dimensional Dirichlet spectrum with respect to Euclidean norm was defined. We consider an analogous definition for arbitrary norms on $\mathbb{R}^2$ prove that, each such norm, set improvable pairs contains badly approximable pairs, hence is hyperplane absolute winning. To this we make careful study some classical results in geometry numbers...

In 1946 Hale described a method for demonstrating acid mucopolysaccharides in sections based on the affinity of these compounds for colloidal iron oxide in acid solution. The combined iron was demonstrated by conversion to prussian blue. It has been found that bacterial capsules and slime are very well stained by Hale's method. This is possibly due to their content of acid mucopolysaccharides, ...

oligonychus afrasiaticus mcg is a key pest on kabkab and khasi date cultivars in behbehan. this research was conducted based on randomized complete block designs with 9 cultivars and 3 replications in behbehan agricultural research station during 2008 and 2009. the main idea of the investigation was the response assessment of these cultivars to the spider mite. the cultivars included kabkab, kh...
