The article substantiates the influence of agrophysical factors and climatic conditions on yield protein gluten content in winter wheat grain. Agrophysical factors, soil moisture during sowing period, tillering phase for various methods basic tillage years Lower Volga region are analyzed. data obtained three (2018–2020) show that a small (by 10–12 cm) black fallow reduces its by 0.25 t/ha (10.6...
wheat grain yield is adversely affected by post-anthesis drought stress conditions in most wheat growing areas of iran. to evaluate the effect of late drought stress on wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of collage of agriculture, shiraz university during 2009-2010 growing season. ir...
Genotypic diversity within host-plant populations has been linked to the diversity of associated arthropod communities, but the temporal dynamics of this relationship, along with the underlying mechanisms, are not well understood. In this study, we employed a common garden experiment that manipulated the number of genotypes within patches of Solidago altissima, tall goldenrod, to contain 1, 3, ...
in order to evaluate some morphological traits of durum wheat genotypes, 18 elite lines selected from advanced regional durum wheat yield trials. these materials along, with two checks dena (durum wheat) and parsi (bread wheat) were examined using rcb design with three replications at isfahan research station in two consecutive cropping season. during the cropping season some trials such as the...
The effects of irrigation water salinity (12 dS m−), imposed at maximum tillering (35−40 days after sowing, DAS) or booting (50−60 DAS) or grain filling (75−85 DAS) stage of wheat, on growth and yield of the crop was demonstrated. The experiment comprised four treatments – I1: irrigation by fresh water (FW) at all three growth stages (control), I2: irrigation by saline water (SW) at maximum til...
The lesion nematode, Pratylenchus thornei, was clearly demonstrated as a parasite of wheat. It reduced plant stands and stunted plants in the field under the environmental conditions found in Sonora, Mexico. Other soil organisms also may have contributed to the problem. The nematode is widely distributed throughout the wheat-growing region, and may be a problem each growing season. Nematicides ...
to investigate the prevalence of cryptosporidium infection in horses, a total of 200 fecal specimens were collected randomly from five farms in tehran. samples were taken during a year, 50 specimens each season. of these specimens, 57 were obtained from caspian pony. the presence of oocysts in the samples was confirmed by modified ziehl-neelsen staining of direct smears of the fecal material fr...
10 The dry and wet deposition of radionuclides released into the atmosphere can be 11 intercepted by vegetation in terrestrial ecosystems. The aim of this study was to quantify the 12 interception of wet deposited Cs and Sr by spring oilseed rape (Brassíca napus L.) and 13 spring wheat (Tríticum aestívum L.). The dependency of the intercepted fraction (f) on total 14 above ground plant biomass,...
Canine Babesiosis is an important worldwide, tick-born disease caused by apicomplexan hemoparasitic from genus Babesia. The aim of the present survey was to identify the current state of Babesia infection in urban and rural dogs in Ahvaz district, southwest of Iran. For this reason, 200 rural dogs from 5 village around Ahvaz and 200 urban dogs (stratified random sampling) referred to the veteri...
wheat root and crown rot known as take-all disease caused by gaeumannomyces graminis var. tritici is one of the most important diseases of wheat worldwide. in iran,the disease has been reported from provinces such as markazi and golestan. in recent years, symptoms of the disease such as stunted and yellow plant, rotted roots and whitened/empty heads have been observed in wheat fields in various...
