The attitude of policymakers and designers of green space is increasing toward to native-ornamental species to plant in the urban space because of their adaptation and resistance against severe weather and ecological conditions which can result in cost minimization and long-term survival in green spaces. Hence, the current study was carried out in the west of Mazandaran Province on three wild a...

مراتع حدود نیمی از خشکی های جهان را در بر دارند و پوشش گیاهی آن در نتیجه تأثیر متقابل محیط و موجودات زنده به وجود آمده است و به عنوان یک اکوسیستم طبیعی مدیریت می شوند. علاوه بر مراتع، راه ها در عصر حاضر نیز از اجزا مهم و زیرساخت های اصلی زندگی نوین و توسعه کشورها به شمار می روند. جاده ها ساخته دست بشر هستند و جوامع گیاهی کنار جاده تحت تأثیر ساخت و ساز قرار دارند. پوشش "رودرال" به مجموعه ای از پ...

introduction: cloning an individual by transferring somatic nuclei into enucleated recipient oocytes has already been well established. this technology also offers new opportunities to restore threatened species with interspecies somatic cell nuclear transfer (scnt). however, few mammalian species have been studied for their reproductive biology whereas huge differences have been observed betwe...

in order to study the tolerance level of different wild barley (hordeum spontaneum) populations to clodinafop propargyl (topic®), a pot dose response experiment was conducted in a completely randomized design with three replications at ferdowsi university of mashhad greenhouse in 2009. cultivared barley (hordeum vulgare) and three wild barley populations (shiraz, boshroyeh, and torogh) were stu...

Drought stress is one of the most important environmental factors affecting growth, development and production of crop plants. Drought tolerance in germination and seedling growth stage is very important especially for crop production in dry regions. Sufficient genetic diversity in cultivated species of safflower is limited and seems to be of potential benefit in search of wild species. In this...

In this study, the karyo-systematic studies on the Iranian wild almond species A .communis L., A. corduchoruom Bornm., A. trichamygdalus woronow, Amygdalus lycioides Var. horrida Spach were done by the karyological methods. The meristem cells of the root tip were used for these studies. In each species, ten suitable metaphase plates were chosen and photographed so that the morphology of the chr...

this experiment was conducted to evaluate the drought tolerance of cultivated (carthamus tinctorius l.) and wild safflower (c. oxyacanthus bieb) populations at research farm of college of agriculture, isfahan university of technology located at lavark-najafabad in 2008. a randomized complete block design with 3 replications was used in each of irrigation levels after 80, 130 and 180 mm evaporat...

Due to genetic erosion over evolution events, the genetic diversity of domesticated safflower species for drought tolerance is limited. Wild species has been considered as useful genetic resources for improvement of abiotic stress tolerance. In this study, a cultivated species (C. tinctorius) was crossed by two wild species (C. palaestinus and C. oxyacanthus) and the genotypes were purified unt...

Wild goat (Capra aegagrus) is one of the most prominent mountain mammals dispersed in many habitats in Iran. However, few studies on the relationship between this species and its habitat have been conducted. This species is recognized as one of the main food source for highly endangered species such as cheetah and leopard. In this study which lasted from fall 2009 through summer 2011, seasona...
