In order to study the response of rice genotypes to different levels of nitrogen (N), an experiment was conducted to evaluate growth and development of 28 selected rice genotypes (improved and local from north of Iran, and cultivated in Central Iran) under two levels of N including 2.85 mM (N concentration of Yoshida solution) and 1.42 mM (half the N concentration of Yoshida solution) from ammo...
Rice bacterial blight caused by Xanthamonos oryzae pv. oryzae is one of the most destructive bacterial diseases of rice in some areas of rice cultivation in the world, especially in the tropics of Asia. The low efficiency of disease management methods, especially chemical methods, has led to more research on recognizing resistant cultivars and understanding resistance mechanisms through the stu...
using a wide range of techniques, including differential scanning calorimetry, x-ray diffraction, rapid visco analyser and fourier transform infera red spectroscopy, some physicochemical properties of the starch fraction of six iranian rice cultivars (tarom, tarome hashemi, neda, ramezani, fajr and kamfirouzi) [1]were studied and compared. dsc data showed that starch granules of different rice ...
Zn deficiency is one of the most important nutritional disorders after macro-nutrients in rice. There are considerable genotypic differences among rice genotypes in response to Zn deficiency. Determination of such differences and introduction of efficient genotypes could lead to significant reduction of fertilizer use for rice production. In this research, some of the most frequently cultivat...
Cold stress is one of the most important environmental stresses for rice especially in temperate and high elevation areas. In present study, the effect of different temperatures, as the main plot, including 25 (control), 10 and 5°C on 12 rice cultivars (including Champa Yasouj, Gerde, Lenjan Askari, Kaamfirouz, Kohsar, Shafagh, Domsiya Mamassani, Dular, Gharib, Hasan saraei, Mosa Tarom and 304)...
Background and Objective: Radon is highly regarded because of its impacts on public health. Northern regions of Iran have a high potential for radon emissions. This research aimed to measure residential radon concentrations in Tarom country- Zanjan and to compare the results with international standards and acceptable values. Materials and Methods: Passive diffusive samplers, Solid State Nuc...
Background and purpose: Transgenic rice is a type of rice that its genetic sequence has been changed to improve its quantity and quality. Bt (Bacillus thuringiensis) transgenic rice expresses Cry1Ab protein and is named Tarom Molaii. There are no studies on the effect of this type of transgenic rice on gastrointestinal health in Iran, so, this study investigated the effect of Tarom Molaii tran...
background and objectives: rice plant requires abundant water during its growth cycle and usually faced with water deficit. drought stress alters the allocation assimilate , root and shoot growth during the vegetative period and also lower tillering, death tillers, lower plant height and flowering delay. the aim of this study was to screen different iranian genotypes and some lines from irri w...
introduction the aqkand cu occurrence, 48 km north of zanjan, is located in the tarom subzone of the western alborz-azerbaijan structural zone. apart from small scale geological maps of the area, i.e., 1:250,000 geological maps of bandar-e-anzali (davies, 1977) and 1:100,000 geological maps of hashtjin (faridi and anvari, 2000) and a number of unpublished perlite exploration reports, prior to t...
there are many problems in yield, quality and and persistence regular bearing in olive trees, one of these problems is nutritional imbalances. this study carried out in order to evaluate nutritional status of olive orchards in tarom region of zanjan province. samples of soil and leaf were taken from 79 olive orchards in june 2012 and 2013 and were analyzed by using appropriate laboratory method...
