Introduction: One of the requirements of the environmental risk assessment of hot rolling industry is the evaluation of the performance of equipment and devices in the industry and identifying subsequent environmental risks. Methods: This was a quasi-experimental study. After classification of the equipments in the production hall of hot rolling at the Kavir Steel Complex, some operations we...

سطح زیر کشت جو به­علت تحمل به خشکی و شوری در سال­های اخیر در ایران افزایش یافته است. به­منظور ارزیابی تعدادی از لاین‏های امیدبخش جو تحت شرایط شور و معرفی لاین‏های برتر، آزمایشی مزرعه‏ای در دو سال کشت پیاپی (1390-1389 و 1391-1390) در شهرستان زرین‏دشت انجام شد. در این آزمایش، رقم نیمروز به­عنوان شاهد به­همراه سیزده لاین امیدبخش جو در قالب طرح بلوک‌های کامل تصادفی با سه تکرار مورد مقایسه قرار گرفت...

به منظور بررسی سازگاری ژنوتیپ‌های متحمل به شوری جو، تعداد 10 ژنوتیپ این گیاه طی سال زراعی 82-1381 در شش ایستگاه تحقیقاتی اصفهان،کرمان،یزد،قم،مشهد وگناباد در قالب طرح بلوک‌های کامل تصادفی در3 تکرار موردارزیابی قرارگرفتند. حداقل هدایت الکتریکی آب آبیاری و خاک در کلیه مناطق اجرای آزمایش به ترتیب 8 و 10 دسی زیمنس برمتر بود. نتایج حاصل ازتجزیه مرکب داده‌ها نشان دادکه اثرمتقابل ژنوتیپ ومکان در سطح اح...

     To improve a complex characters such as grain yield with low heritability, indirect selection through other characters and selection index based on different effective traits were used. For this purpose, 96 F3 families derived from Roshan and Kavir crossing, together with parents, F1 and F2 progenies were cultivated. In lattice design with 2 replications under drought stress conditions in ...

Breeding programs strategies depends on genetical mechanism of selection traits. In the present research, generation mean analysis with joint scaling test was performed to determine the gene action. F1, F2 and F3 generations, derived from Roushan and Kavir cross along with their parents were sown in a partial Lattice design with two replications under stress condition at the research field of S...

A generation mean analysis was conducted to study genetic of yield and yield related traits of bread wheat in drought stress condition. In this research F1, F2, BC1 and BC2 generations were developed created using Kavir and Roushan as parents. The generations and parents were evaluated in a randomized complete block design with three replications and the traits including yield, flag leaf area, ...

Kernel hardness is one of the most important characterizations on end-use quality of bread wheat and also used for their marketing classification. Kernel texture, mainly controlled by one major locus (Ha) located on the short arm of chromosome 5D. Two tightly linked genes as puroindolin a , and b covered by this major locus and designed as Pina and Pinb respectively. When both puroindolines are...

Zilu is a flat heat resistance cotton rug, which was used in hot and dry parts around Iran’s Dasht-e Kavir like Yazd, Meybod, Ardakan, Ardestan, Kashan, and Semnan in order to protect places like Mosques, public and religious places, and houses from the heat. But these days the creation and usage rate of this native art is decreasing and only a few weavers are still in this business. Due to the...

Drought, an abiotic stress, considered as one of the factors limiting food resources. The plant responses to adaptive to such a condition are accompanied with changes in the expression pattern of some functional as well as regulatory genes. The MYB proteins include a big family of transcription factors which are highly important in regulating development process and immunizing responses of plan...
