Background: Aflatoxins are toxic fungal metabolites enable to contaminate a wide range of natural substrates. This contamination can be host-specific for different plant species. In this study, the ability of a toxigenic Aspergillus parasiticus to produce various aflatoxins on major Iranian cereals was evaluated with special focus on plant susceptibility to toxin production at cultivar level. M...
Response of Iranian Rice Recombinant Inbred Lines (Oryza sativa L.) to Salt Stress in Seedling Stage
Study of the morphological genetic diversity of 114 lines, which have been derived from the crosses between Tarom Mahalli and Khazar cultivars, has been performed at seedling stage as completely randomized design at the normal condition and salinity stress of 8 dS.m-1 in a hydroponic system. Significant differences were detected between genotypes for all traits. Mean of comparison demonstrated ...
The development and production of genotypes with high quality is one of the important purposes in the plant breeding programs. In order to evaluate the qualitative traits, 77 lines of rice (F12 generation) in comparison to five control cultivars (including TaromMahalli, Sang-e-Tarom, NokSeyah, Fajr and Deilamani) were studied in the Biotechnology Laboratory of Sari Agricultural Sciences and N...
The study area is located about 25 km northwest of Takestan city, within Tarom-e-Sofla metallogenic belt. This area is covered by a widespread Eocene andesite to dasite volcanic rocks affected by Oligo-Miocene monzogranite to granodiorite igneous bodies which altered them to silicic, argillic zones as long as hypogene sulfide vein-veinlet mineralization (e.g. galena, sphalerite, pyrite, rare ch...
The studied area is a part of Tarom Mountains and is located in 40 km north of Zanjan. The area is formed mainly by Tertiary volcano-sedimentary and plutonic rocks, which are mostly altered. Based upon geological setting, the hydrothermal alterations in the area are divided into two groups: (1) Regional alterations consisting of potassic, sericitic and propylitic types. (2) Structurally control...
In order to develop a high yielding rice cultivar with optimum cooking quality, a cross was conducted between two rice cultivars Khazar, high yielding and resistant to blast disease and Daylamani Tarom, with good cooking quality in 1990. Forty pure lines were selected and compared for high grain yield in 1996. Ten selected lines together with two check cultivars Dasht and Onda were tested in ...
in order to investigate rice competition ability against weeds in direct-seeding and transplanting systems afield experiment was conducted at mahmud abad region of mazandaran province on 2011 growing season. experimental treatments were studied in a split plot factorial design based on randomized complete blocks with three replicates. direct-seeding and transplanting of rice in wet seedbed were...
abstract striped rice stem borer, chilo suppressalis walker (lepidoptera: pyralidae) is one of the important pests in rice fields of mazandaran. therefore, almost the farmers of northern iran apply several pesticides in nurseries for the pest control; while it is causes environmental risks and damages to human. in this research two different items including, 1- study of egg masses density in nu...
شوری آب و خاک هر ساله موجب کاهش قدرت تولید اراضی و عملکرد محصولات زراعی از جمله برنج در نواحی خشک و نیمه خشک و همچنین اراضی ساحلی می گردد. جهت مطالعه خصوصیات رشد (مورفولوژیکی، فنولوژیکی، فیزیولوژیکی) و عملکرد ارقام و لاین های منتخب برنج در شرایط شوری تحقیقی درسال زراعی1392 با استفاده از آزمایش تجزیه مرکب در قالب طرح بلوک های کامل تصادفی با سه تکرار در مزرعه ای واقع در آمل (مزرعه نرمال) و جویبار...
it is very important to analyze the rice market structure in mazandaran province, as this province is competent to produce rice. mazandaran rice market was analyzed by completing 55 questionnaires in producer, wholesaler and retailers level, randomly in 2009. results show that marketing margins of two varieties namely- local (tarom) and multi-product- were 5850 and 3700 rials, respectively; als...
