Abstract Amphibole-dominated dehydration melting of gabbro is the primary process responsible for genesis adakites, low-K tonalites, modern trondhjemites, and plagiogranites as well Archean tonalite-trondhjemite-granodiorite suites that represent earliest examples continental crust. Previous literature has mostly focused on role Al-rich amphibole during anatexis a mafic source many these studie...

abstract due to limited water resources in agriculture, application of each strategy to economize water use and increase area under cultivation is very important. one such strategy is deficit irrigation. for optimal planning of deficit irrigation, it is necessary to determine different sensitive stages of plant water shortages. in this study the effect of deficit irrigation on growth and yield ...

By studying the type specimens and field works from locus classicus, it became clear that the two species of Silene eremicana and S. goniocaula which are considered as conspecific in the Flora Iranica are distinct species. Silene commelinifolia var. isophylla is considered as a synonym of S. eremicana. The numbers of herbarium specimens (voucher) are emended and the descriptions of each species...

heat stress is one of the main obstacles for crop production in many areas of the world including southwest of iran. in order to evaluation the effect of heat stress on yield, yield component, and mopho-phenological traits of wheat, an experiment was conducted during 2010-2011 under normal (optimum sowing date) and heat stress (late sowing date) conditions on 11 wheat genotypes including yavaro...

one of the most important forms of preharvest damage to wheat is caused by sunn pests. the insects insert their mouth parts into the immature grain and while injecting their saliva suck the milky juices. flour from damaged wheat results in low baking performance due to the bug proteolytic enzymes’ injected which cause the breakdown of gluten structure in the dough. in the present study three wh...

iran is widely drought prone, considering its semi-arid climate. eleven wheat cultivars differing in yield potential and drought resistance were employed to determine the possible relationship among grain filling rate and duration, stem reserves remobilization and grain yield under either irrigated (ir) or non-irrigated (nir) conditions at gerizeh research station in sanandaj for a duration of ...

this research was carried out for the purpose of urea fertilizer, organic matter and pgpr bacteria effects on yield and some growth indices on winter wheat (triticum aestivum c.v alvand). this research was carried out with factorial experiment on completely randomized design with 4 replication in greenhouse. treatments included bacteria 4 levels, without bacteri, a. brasilense, a. chroococum, i...
