In order to investigate of genetic diversity in sainfoin based on seed yield and related traits, 36 ecotypes including foreign and Iranian ecotypes, an experiment was conducted using a lattice design with two replications in researches station in Natural Resources and Agricultural Researches Center of East Azerbaijan province. Analysis of variance revealed significant genetic diversity among ec...
the present study has tried to accomplish an analysis of margaret atwood’s novels oryx and crake, and the year of the flood in the light of posthuman and cyborg theories. considering posthumanism as a critical reading of some notions of humanism focus of which in this thesis has been identity, new definitions for humanity and human identity are formed. haraway’s cyborg, as one possible new figu...
german chamomile (matricaria chamomilla) is one of the most important industrial medicinal plant. inthis experiment the effects of foliar application of salicylic acid in different levels (0, 10-2, 10-4, 10-6) wereinvestigated on the floral traits and essential oil content of three ecotypes (italian, tehran, zabol) ofgerman chamomile. the results showed that maximum percentage of essential oil ...
in his last years of life americans had almost forgotton steinbeck, and those who had not, occasionally criticized him for supporting and praising the u. s. military intervention in the vietnam war. althought ateinbeck incorporates different themes into his works, each one bears many signs of his concern and sympathy for america and the american common people in particular. steinbecks to a god ...
Phenotypic mosaic trees offer an ideal system for studying differential gene expression. We have investigated two mosaic eucalypt trees from two closely related species (Eucalyptus melliodora and E. sideroxylon), which each support two types of leaves: one part of the canopy is resistant to insect herbivory and the remaining leaves are susceptible. Driving this ecological distinction are differ...
چکیده: جنس مریم گلی(salvia.l) از تیره نعناعیان با حدود 900 گونه گسترش وسیعی در سرتاسر دنیا دارد. مراکز اصلی تنوع جنسsalvia نواحی مدیترانه ای آسیای مرکزی آمریکای و جنوب آفریقاست. این جنس دارای 58 گونه علفی و پایا در ایران است که 17 گونه آن انحصاری است. اعضاء این جنس دارای متابولیت ثانویه بسیاری نظیر اسانس ها و ترکیبات فنلی است که دارای خواص دارویی بوده و در مقابل علف خوارها وپاتوژن ها نقش های ت...
Endophytic fungi live their whole life within host tissues usually without any visible symptoms. Their vertical transmission (seed-plant-seed) has been well described and documented. However, horizontal transmission (plant-plant) needs more clarification. The aim of this study was to assess the extent to which endophytes move vertically in ecotypes of perennial ryegrass and whether there is evi...
during 2010-2011 a faunistic survey was carried out for collection and identification of edaphic mesostigmatic mites (acari: mesostigmata) in jiroft and suburb. mites were extracted from soil samples by berlese funnel. the mites were cleared in nesbit fluid and were mounted in hoyer medium on microscopic slides. in this study 43 spices from 26 genera and 16 families were collected and identifie...
Bacteria from the Bacillus cereus group exhibit genetic and physiological diversity through different ecotypes. Here, we present the draft genome sequences of 20 bacterial strains belonging to the contrasted psychrotolerant and thermotolerant ecotypes.
The genus Salvia is a valuable origin of structurally diverse terpenoids. In a project directed at structurally interesting bioactive metabolites from Iranian Salvia species, we studied Salvia reuterana. Two new labdane diterpene, 6β,14α-dihydroxy-15-acetoxysclareol (1), and 14α,15- dihydroxy sclareol (2), were isolated from the aerial part of the plant. Their structures were established mainly...
