The ability to reconstruct and identify intracellular protein signaling and biochemical networks is of critical importance in biology today. However, the ability to dynamically measure and collect data from every protein/node within the network is impossible with current methodologies. Consequently, approaches are needed that can use experimentally collected data to accurately reconstruct and e...
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...
to study the impact of growth factor bacteria , humic acid and alga extract in drought stress condition a test is established in form of completely random blocks and spilt plot in 4 replications in a field in mahallat in arak province in 1389. two primary plots including irrigation and stress and secondary plots including growth factor bacteria ,humic acid and alga extract, ascophylu...
Condition factor of fish species is very important parameter for understanding fish biology and pathology. For that purpose, we sampled 120 fish individuals from the Sava River at four locations (Posavina region), where most of them belongs to the Cyprinidae family while the others belonging to the families: Percidae, Siluridae, Ameiuridae, Esocidae and Gobiidae. In total fish sample we found t...
In this study, the chronic toxic effects of Pb (II) on common carp, Cyprius carpio were investigated using several biomarkers at different levels of biological functions for assessing changes in ecosystem quality. In a bioassay, common carp juveniles were individually exposed to different dose of heavy metal, Pb II (0, 0.45, 0.89, 1.34 mg.l-1) for 28 days. Morphological indices such as hepat...
Wheat is mostly cultivated at rainfed condition in Iran, so, water deficit stress has much effect on yield reduction. Hence, breeding activities are necessary for introduction of wheat tolerant genotypes to water deficit stress. In order to estimate the heritability and genetic correlation between traits of 36 wheat genotypes, an experiment was conducted in two separate conditions (water stress...
The present study describes the length-weight relationship (LWR), length-length relationship (LLR) and condition factor of the wild population of the shrimp Macrobrachium macrobrachion from the rivers of Côte d’Ivoire (West Africa). Samples were randomly collected from small-scale shrimp fisheries using bamboo traps. Of the thirteen analyzed morphometrics characters, only the second pleura widt...
