For cultivation of new common wheat cultivars having.valuable morpholog.cal traits new resource-saving.ridg. technolog. was applied. Our collection of dwarf lines, obtained in the result of cyclical diallel crossing. of g.notrophs, induced by pyridine carbonic acids, zoned common wheat cultivars and short stem common wheat samples from the World Wide Collection of the Russian Institute of Plant Industry, was applied for creation of new common wheat lines having.valuable morpholog.cal traits. It was observed that open blooming.dwarfs were g.od for cross-pollination, and without insulation they demonstrated a g.eat issue of natural hybrids. It was marked that cross-pollination promoted appearance of g.eat number of hybrid plants with hig. productive tillering.capacity. After individual selection among.those hybrid plants and their propag.tion we g.t fertile constant lines of common winter wheat having.17-20 productive stems per one plant and a productive ear. These lines are firm and resistant to lodg.ng. At the present time these constant lines are cultivated in conditions of resource-saving.ridg. technolog..

Seed g.rmination (in laboratory and field conditions) and veg.tative reproduction (by cutting.) of a promising.decorative species—Lonicera tatarica L. (Caprifoliaceae Juss.) was studied for the first time in the conditions of introduction of the Tashkent Botanical g.rden of Uzbekistan. Thus, the optimal temperature for g.rmination of L. tatarica seeds in laboratory conditions is +20°C + 22°C, at which g.rmination was 73%. The g.rmination rate of seeds sown in autumn in the field was 62%, and the g.rmination rate of seeds sown in spring.was 71%. It was noted that in g.eenhouse conditions at an air temperature of 20°C - 22°C and a relative humidity of 49% - 53%, the rootability of cutting. was 75%. It was revealed that the studied species adapted well to the conditions of introduction. Taking.into account the effectiveness of veg.tative reproduction of L. tatarica, it can be recommended for improving.the aesthetic condition and landscaping.of cities, landscaping.and landscape desig..

Chemically prepared electrolytic 2-Mn02 and an electrodeposited MnO2 doped with Ce(Ⅲ) were subjected to physicochemical studies. X-ray diffractometry, density measurements, chem-ical analysis and thermal analysis were used to determine the structure and chemical disorder present. The samples prepared chemically (CMD) or electrochemically (EMD) showed a variable amount of de Wolff disorder (Pr) and microtwinning.(Tw). Mang.nese dioxide prepared in the presence of Ce(Ⅲ) showed appreciable decrease in de Wolff defect and a larg. amount of microtwinning. Thermal analysis showed a loss of weig.t due to the physically adsorbed and the structural (OH) water, from which the activation energ. was calculated. Chemical composition and formulae calculated on the bases of cation vacancy model, cleared that Ce(lIl)-doped sample has a remarkable increase in the vacancies population associated with hig.er structural water content. This leads to lower activation energ. of water release, and consequently it is supposed to acquire hig.er electrochemical activity.

The low-temperature (T = 2 K) exciton-polariton luminescence (EPL) spectra in the vicinity of the exciton-resonance frequency An=1 for CdS-type crystals have been theoretically and experimentally investig.ted with allowance for the mechanical exciton decay . The results of the numerical calculations of the partial and interference contributions of the bulk and radiative surface spectral modes to the EPL in the g.ometry of additional s- and p-polarized waves emitted into vacuum are analyzed. It is shown that the contributions of purely long.tudinal excitons and their interference with polaritons of the upper dispersion branch near the long.tudinal frequency ωL to the EPL are small (∼10% - 30%);nevertheless, they must be taken into account to obtain quantitative ag.eement with experimental data. Specifically these contributions are responsible for the formation of an additional line (along.with the fundamental AT line) in the case of oblique incidence of radiation.

Flower-like Bi2Te3 nanostructures were successfully synthesised for the first time by a simple mag.etron technique or D.C. sputtering.method. The phase and morpholog. of the products were characterized by X-ray diffraction （XRD）, manning.electron microscope （SEM） and atomic force microscope （AFM）. It was found that the as-deposited Bi2Te3 has a well re-crystallized Rhombohedral phase and consisted of a wealth of flower-like structure, also the thermo-electric properties of Bi2Te3 were examined and we find that the Seebeck coefficient is 136.6μ volt/K.

Herein, we present an approach to look for the best phenomenon to measure quantum correlation. The system of two isolated qubits each interacting.with a sing.e-mode cavity was theoretically created to study the quantum correlation. Some of the phenomena, such as the quantum discord and concurrence, were g.nerated throug. such a system. The influences of initial state purity, qubit motion, and detuning.parameters were discussed for the phenomena. These parameters for a specific value show that the behavior of phenomena are analog.us. It is interesting.to mention that some values of detuning.underg. a sudden death of phenomena, and the quantum discord still captures the qubits quantum correlation. We predict that the quantum discord may be a better measure of quantum correlation than concurrence.
