in order to induce of genetic variation and selection of genotypes with desirable traits, seeds of three varieties of rapeseed sarigol (pf), rgs003 and zarfam were treated with different doses of gamma ray 500, 700 and 900 gy. to confirm the stability of the induced genetic traits, 66 mutant lines from m4 generation were studied in a randomized complete block design with three replications. twe...

One of the factors which can kill or decrease the viability of bioleaching bacteria is the creation of toxicity due to the process of metal release from mine stone. This toxicity is partly due to the presence of arsenic in mine stone. In the present study mutagenesis method was used to improve the bioleaching process performance by using UV and gamma rays. The influence of radiations (UV& gamma...

Trichoderma species have been famous for production of cellulases with relatively high enzymatic activity. However, attempts to use their cellulolytic enzymes in the bioconversion of cellulosic wastes have not been successful because of high cost of production and low enzymatic yields. This study aimed to obtain gamma-induced mutants of T. viride with enhanced extracellular cellulase production...

  Yrast states in mirror nuclei 55Co and 55Ni have been populated with a radioactive ion beam using the Isotope Separator On-Line method. A shielded array of 7 Compton suppressed germanium detectors recorded reaction gamma-rays. For channel selection, an array of 128 independent silicon detectors was used to differentiate exit channels with different number of proton and alpha particles emitted...

The objectives of the present research were to evaluate the variability induced by gamma-irradiation among a population of M8 sunflower mutant lines and to identify molecular markers associated with different seed germination traits. Experiments were carried out under well watered and water-stressed conditions using a randomized blocks design, with three replications. The studied traits consist...

Lectin protein is considered as an important anti-nutrient factor in soybean seed. A low quality soybean proteins is associated whit the presence of lipoxygenase protein due to its unfavorable flavor. This research was conducted at the Sari Agricultural Sciences and Natural Resources University, during 2008-2009 to evaluate the effect of Gamma rays on anti-nutrient protein of Hill cultivar. M1 ...

 Wheat is regarded as a strategic product among the cereals in the world. The bread quality of this product is affected by the physical and chemical properties of wheat gluten. In order to achieve lines with superior qualitative characteristics, gamma irradiation was applied on Roshan cultivar with high cultivation area in a cooperation between Atomic Energy Organization of Iran and the Interna...

Studies on physical induced mutagenesis, gamma rays were performed by exposing the healthy and dry seeds of cowpea variety CO 4 to gamma rays 20, 30, 40, 50, 60 and 70 kR. The study was to evolve economically important mutants with varied seed coat colour as against dark grey coloured seed coat of CO 4. The LD50 value was found at 50kR for 60 Co gamma rays. Under field conditions, germination, ...
