This study was conducted to evaluate the effects of water stress on growth indices and phenological traits and growth indices of Thymus kotschyanus during 2010 and 2011 growing seasons. A field experiment was carried out with three irrigation regims (T20, T50 and T80 representing irrigation after 20, 50 and 80% soil water depletion, respectively) using a randomized complete block design with f...
In the rangelands of Iran, the lack of appropriate grazing management is one of the major problems ultimately leading to untimely and excessive grazing intensity of forage. Accordingly, most of the rangelands show a retrogression trend and poor conditions. In forage species, phenological stage is one of the most important criteria for range management. Bromus tomentellus species is an ...
This study was conducted to determine the chemical composition, metabolizable energy, digestibility and ability of gas production of Poa trivialis. Samples was collected at three phenological stages including: vegetative growth, flowering and seedling on two different elevations of 1300 to 1500 m and 2000 to 1800 m asl in Neor and Hir region as the first and second sites, respectively. Testing ...
Studies dedicated to understanding the behavior of pathogens in relation to their hosts are the starting point for any breeding program aimed to develop resistant cultivars. The objective of this study was to analyze the resistance to Septoria tritici Rob in 77 F11 progenies of wheat derived from the three-way cross Tadinia × (Yecora rojo × UC554) in the phenological stages of seedling, tilleri...
Phenology is a broad science topic of Ecology. Study of phenology for regulating of animal grazing programs and determining of palatability and nutritive value of plant species at different stages of vital in range is important. This study was carried out to determine the chemical composition and nutritive value of Salsola vermicolata and Suaeda fruticosa that are halophyte plants, in three phe...

چکیده کنه تارتن دو لکه ای tetranychus urticae koch یکی از چندخوارترین آفات شناخته شده محصولات کشاورزی دنیا به حساب می آید. در این بررسی جمعیت تخم و مراحل فعال این کنه در شرایط آلودگی طبیعی و مصنوعی در برگ های 8 رقم لوبیا در سال 1392 در گلخانه و مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه ارومیه موردمطالعه قرار گرفت. آزمایش به صورت طرح کاملاً تصادفی برای شرایط مزرعه در10 تکرار و برای شرایط گلخانه ای...
Development of wheat (Triticum spp.) is primary driven by temperature, but is also affected by other factors such as vernalization and photoperiod. Crop growth and development are often described in terms of calendar days. However, determining the development in terms of thermal time or physiological time is more accurate because it is an accumulation of the caloric energy needed for the o...
desert and marginal lands of playas which are covered with halophyte shrubs, play a great role in supply of forage for livestock as winter rangelands. in this research, plant samples were collected from four palatable halophyte species for zandi sheep of qom desert rangelands including seidlitzia rosmarinus، halocnemum strobilaceum، alhagi camelorum and tamarix passerinoides in two phenological...
abstract foreign and iranian cultures are far distinct in the constraints imposed on writing and translating for children, since the iranian literary system is mainly concerned with cultural and religious instructions which lead to manipulation of translated texts. this study sought to identify the cultural and social constraints and norms which determined the strategies applied in the transl...
