During the period from 1997 to 1998, samples of wheat leaves were collected from different wheat farms in Fars and Kohgiluyeh & Boyrahmad provinces to identify the causal agent of wheat leaf blight. On the basis of LOPAT tests and production of fluorescent pigment on KB medium, 181 bacterial isolates were recovered from the samples. Based on biochemical, physiological and pathogenicity tests, t...
Proof of species existence in different regions can be useful for studying the migration pattern of the species. The use of non-invasive methods such as eDNA can be very effective in tracking and dispersing and improving the management of water resources and species. In this study, 15 water samples were taken from different areas of the southern Caspian Sea basin. Amino-modified silica-coate...
the aim of this experiment was the study of dry matter and nitrogen (n) accumulation, remobilization and harvest index in different wheat cultivars. five bread wheat cultivars (darya, kuhdasht, shiroudi, tajan and zagros) and two durum wheat cultivars (arya and dena) were studied under optimum growth conditions during 2008-2009 at research field of gorgan university of agricultural sciences and...
growth analysis is a valuable method in the quantitative analysis of crop growth, development and crop production. there are many regression models to describe the sigmoid growth patterns. by considering that, the parameters of non-linear regression models have physiological meanings, they are preferable relation to linear regression models. the aim of this study was to collect and evaluate the...
objective: in order to investigate effects of different concentration of gibberlic acid (ga3), kentin and putrescinepoly amine, on germination of three cultivars of wheat under salinity stress. methods: the experiment was carried out as factorial based on completely randomized design with four replicates in laboratory of agronomy and plant breeding, department of agriculture in islamic azad uni...
in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...
objective: in order to investigate effects of gibberlic acid (ga3) and sprimidin poly amine on germination of three cultivars of wheat under salinity stress. methods: the experiment was conducted as factorial based on completely randomized design with four replicates in agronomy and plant breeding laboratory of agricultural department of islamic azad university, varamin-pishva branch in spring ...
genetic diversity is necessary for breeding program and increasing genetic gain of selection in crop plants. with the onset of spring growth, spring cold stress is a problem for wheat crops at heading and also may be damaged some other parts of this plant. the aim of this study is the investigation of genetic diversity duo to artificial cold stress on the physiological traits, chlorophyll a, ch...
in order to investigate the effects of different levels of nitrogen rate on yield and seed yield components of wheat cultivars, an experiment was conducted on araghi mahalleh (gorogan) research farm in 2008. treatments, nitrogen in the form of urea (0, 90, 180 and 270 kg/ha) and cultivars (tajan, falat and n81-18) were arranged as factorial based on randomized complete block design with four re...
تخم ها و لارو های شب پره مدیترانه ای آرد، ephestia kuehniella (zell.)، به طور وسیعی در برنامه های کنترل بیولوژیک به منظور پروش پارازیتویید ها و شکار گر ها مورد استفاده قرار می گیرند. در این تحقیق، واکنش های تغذیه ای، فعالیت پروتئولیتیک و آمیلولیتیک گوارشی لارو های سن پنجم همراه با برخی پارامتر های زیستی e. kuehniella روی آرد نه رقم گندم تحت شرایط آزمایشگاهی بررسی شدند. طولانی ترین دوره ی لاروی ...
