چکیده مجموعه حاضر با هدف معرفی و ارائه ی توصیفی برای اصطلاحات رایج در دانش معنی شناسی تهیه شده است. برای دستیابی به چنین هدفی سعی بر آن بود تا صرفاً به واژگان نقش مند در شاخه ی عمده ی معنی شناسی زبانی توجه شود. در حوزه معنی شناسی زبانی، به اصطلاحات در شاخه ای از این دانش، یعنی معنی شناسی نظری (theoretical semantics) و آنچه معنی شناسی کاربردی (applied semantics) نامیده ایم، اشاره شود. و هدف از ت...
soil and water salinity is a major constraint in arid and semi-arid regions. in order to study the impact of water salinity on physiological characteristics and dry matter production of six linseed genotypes, a 4-replicate factorial randomized complete block pot experiment was conducted. salinity consisted of four levels: 0 (control), 35 (low salinity), 70 (intermediate salinity) and 105 mm (se...
Nematodes are important pests of soybean throughout the world and cause high yield losses. As a control strategy, the identification of resistance genes is an important aim of breeding studies. Plants possess resistance genes (R), which are responsible for the recognition of pathogens and activation of the defense system. R genes and resistance gene analogs (RGAs) possess conserved domains, fro...
Sixteen genotypes developed through hybridization and mutation breeding techniques were evaluated during the year 2003-04 on nine locations covering most of the area of Punjab province including Faisalabad, Toba Tek Singh and Jhang. NIAB-IRRI-9, Jhona-379 salt tolerant genotypes and super Basmati, a salt sensitive variety were included as standard checks. The tested material (six genotypes) was...
To evaluate seed germination and seedling growth of safflower in moisture stress, germination of 15 genotypes at four water potential levels (ψ: 0, -0.4, -0.8 and –1.2 Mpa) was tested by Polyethylene glycol (PEG6000). Maximum germination (Gmax), germination rate index (GRI), time length to reach 50% germination (T50), rootlet length (RL) and shootlet length (SL) were investigated. Effects of wa...
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...
In order to determine the most effective indices for quantifying drought tolerance and identify genotypes that are tolerant to water stress in bread wheat, 50 bread wheat genotypes were compared in a randomized complete block design with three replications under both the non-stress dry farming with two complementary irrigation and the water stress dry farming conditions in Khorramabad, Iran. An...
background and aims: rotaviruses are the main cause of gastroenteritis in the young of human and a variety of animals in the world. rotavirus g6 and g10 are the most prevalent genotypes in cattle worldwide, but are also found in human with possible origination from animals. materials and methods: in this work, we have detected the g6 and g10 genotypes of bovine rotaviruses isolated from diarrhe...
To evaluate the phenological stages and yield of wheat cultivars in response to the change of planting date and application of paclobutrazol, a field experiment was conducted in two years, 2020-2021 and 2021-2022, in Izeh city located in the northeast of Khuzestan, Southwest Iran. The experiment had three replications in a split factorial randomized complete block design. The main factor includ...
