the genetic diversity of a large number of pistachio genotypes grown in iran is not exactly known. most of the studies on genetic diversity of iranian pistachio varieties are based on morphological characteristics or isozyme markers. in the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by amplified fragment length polymorphism (...
Low productivity of pilosae type lentils grown in South Asia is attributed to narrow genetic base of the released cultivars which results in susceptibility to biotic and abiotic stresses. For enhancement of productivity and production, broadening of genetic base is essentially required. The genetic base of released cultivars can be broadened by using diverse types including bold seeded and earl...
Drought stress is one the most limiting factors for crop production worldwide. The wide ecological and environmental dispersion of crop wild relatives, generates a high potential of their adaptive diversity to abiotic stresses such as drought. In this study 21 (including 10 cultivated and 11 wild barley (Hordeumvulgaressp. spontaneum))genotypes were evaluated under three soil water conditions f...
to evaluate and compare the chlorophyll content, carotenoid, protein, peroxidase and polyphenol oxidase in different barley species in iran, 49 genotypes belonging to 5 barley species were employed in a completely randomized design with three replications in greenhouse conditions. a high level of within and between species variation was detected. in all the species, significant positive correla...
pears (pyrus spp.) belongs to the rosaceae family, which have been cultivated formore than 3000 years. pears are among the most important fruits in all the temperateregions in about 50 countries of the world. the objectives of this study were to classifypear genotypes based on qualitative and quantitative characteristic and determination oftheir genetic distance. evaluation of genetic diversity...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
The wild relatives are important sources of genes for some desirable traits and adaptation to environmental conditions that can be exploited to enrich the cultivated safflower gene pool. In this study, genetic relationship and finding chance of specific markers between three species of the genus Carthamus, including tinctorius, lanatus and oxyacantha were evaluated by 9 ISSR primers. The s...
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...
کنه¬های شکارگر زیر راسته پرواستیگمای مرتبط با عرصه¬های جنگلی و مرتعی منطقه الشتر طی سال¬های 1391-1392 مورد مطالعه قرار گرفت که در این برسی جمعاً 15 گونه متعلق به 11 جنس از 7 خانواده جمع-آوری و شناسایی شد. که یک خانواده برای اولین بار از ایران که با علامت(*) مشخص شد و 3 گونه برای اولین بار در دنیا شناسایی و توصیف شد. که با علامت(**) مشخص شد. لیست گونه¬ها در ذیل ذکر شده است family stigmaeidae: ge...
Since the recognition of hantavirus as the agent responsible for haemorrhagic fever in Eurasia in the 1970s and, 20 years later, the descovery of hantavirus pulmonary syndrome in the Americas, the genus Hantavirus has been continually described throughout the World in a variety of wild animals. The diversity of wild animals infected with hantaviruses has only recently come into focus as a resul...
