To evaluate genetic diversity and to determine the relationships between yield and other importante traits among bean genotypes, an experiment was conducted in Random Completely Block Design (RCBD) with three repetitions under both normal and drought stress conditions in 2015-2016 crop season on 30 bean genotypes at Tehran University research farm. The results of variance analysis indicated hi...
Safflower (Carthamus tinctorius L.) is one of the multi-purpose oilseed crops which has a high adaptation to different conditions such as resistance to drought and it is suited to be grown in arid and semi-arid regions such as Isfahan province. Root rot disease is an important soil-borne disease of safflower in Isfahan, which can be caused by different pathogens. The objective of this study was...
Extended Abstract Introduction and Objective: Brassica napus (L.) one of the most important oilseeds in temprate climates. In the most breeding programs, especially when comparing several genotypes in different environments, due to the interaction of genotype×environment, genotypes show different performances in different environments. Therefore, to accurately estimate grain yield, multi-envir...
به منظور بررسی و ارزیابی شاخصهای تنش خشکی در روش آبیاری قطرهای نواری بر عملکرد و اجزای عملکرد دانه، عملکرد روغن، درصد روغن دانه و کارآیی مصرف آب دانه، آزمایشی در دو سال زراعی 90-1389 و 91-1390 در ایستگاه تحقیقات کشاورزی بهبهان اجرا گردید. آزمایش به صـورت کرتهای یکبار خـــــرد شده در قالب بلـوکهای کامل تصادفی با 4 تکــرار اجرا شد. فاکتور اصلی شامل مقدار آب در آبیاری قطرهای نواری در چهار سط...
نقش قارچ اندوفیت Pirifomospora indicaبر برخی صفات فیزیولوژیک گیاه توتفرنگی تحت شرایط کشت هیدروپونیک
Microbial endophytes, which are considered as the most important soil microorganisms, increase the yield of their host plants by creating changes in their genetic, physiological and ecological traits. Pirifomospora indica fungus is a member of Sebacinales order, which increases plant biomass and resistance to living and non-living stresses. In this study, effect of different concentrations [0 (...
In this paper, we emphasize the need for data cleansing when clustering large-scale transaction databases and propose a new data cleansing method that improves clustering quality and performance. We evaluate our data cleansing method through a series of experiments. As a result, the clustering quality and performance were significantly improved by up to 165% and 330%, respectively.
Conservation tillage is an energy efficient and low cost tillage system to improve soil environment compared with conventional tillage systems. However, the rice residue management becomes an "impossible to achieve" task due to high soil moisture content at harvest time and the thickness of rice straw. Disc type furrow openers are used for both seed drilling as well as straw cutting during no t...
Background :The cag pathogenicity island includes a number of genes, including cytotoxin-associated protein A (cagA) and vacuolatingcytotoxin (vacA) genotypes, which are associated with bacterial virulence. Although the role of cagA and vacA in the virulence of Helicobacter pylori (H. pylori) is well-established in epidemiological studies, the relationship between the cagA and vacA genotypes ...
Nowadays, the root characteristics as one of secondary traits along with grain yield are used to response evaluation of rice genotypes under deficit irrigation. Thus, to evaluate the root traits of 40 irrigated rice genotypes to water limited condition a pot experiment was performed in 2014 at Rice Research Institute (Rasht), Iran. Irrigation treatment was applied in two levels include con...
Salinity tolerance of four grape genotypes [GharaUzum, Hosseini, AghUzum and Keshmeshi] was studied under various salinity levels (25, 50 and 100 mM NaCl). As a result, growth indices were significantly (P<0.05) reduced by salinity, whereas Cl- and Na+ contents in the plant parts were increased. Cl- accumulation exceeded than that of Na+ in all treatments. Among the genotypes studied, GharaUzum...
