to evaluate the reaction of some wheat advanced lines and cultivars to yellow rust at seedling stage, seeds of 200 accessions were planted in 5cm diameter pots (4-6 seeds per pot) in greenhouse. the seedlings were inoculated with fresh harvested urediniospores of two different races of puccinia striiformis f.sp. tritici (134e134a+ from karaj and 134e142a+ from maragheh, iran) when the first see...
Sagitaria trifolia, Alisma plantago-aquatica and Echinochloa spp. are among the most important damaging weeds in paddy fields. In this research, Alternaria pellucida was isolated from the weeds and then its pathogenicity effects was examined on these weeds and five other rice cultivars, including two bred (Sepidroud and Khazar) and three landraces (Ali Kazemi, Hashemi and Binam), in a completel...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
For evaluation of the reaction twenty of spring wheat cultivars under complete irrigation (control) and drought stress condition starting before booting stage, an experiment was conducted in split plot basis of Randomized Complete Block Design with 4 replications in two cropping years (2010-2011 and 2011-2012) in research farm of Agriculture Faculty, University of Tabriz. The results of varianc...
In order to study the physiological and morphological characteristics of canola cultivars at different planting dates, an experiment was carried out in 2008-2009 at the Agriculture Research Station of Yasouj. A factorial with Randomized Complete Block Design with four replications was conducted. Four planting dates (September 12, September 22, October 2 and October 12) and four cultivars (Zarfa...
Ten cultivars and 13 germplasms of white clover (Trifolium repens) were evaluated in the greenhouse for resistance to the southern root-knot nematode, Meloidogyne incognita race 4. One hundred plants of each cultivar or germplasm were rated for percentage of the root system galled (PRSG) at 60 days after inoculation with root-knot nematode eggs. Tillman (9%) and SRVR (19%) had the highest perce...
This research was conducted to study the role of phenology in wheat cultivars’ reaction to salinity stress. The experiment was carried out as factorial, based on a randomized complete block design with three replications, in Bu-Ali Sina University, Hamadan, Iran. Treatments included four wheat cultivars (Alvand, Toos, Navid and Sayson) and five levels of water salinity (0, 4, 8, 12 and 16 dS/m)...
Insertion-deletion (indel) polymorphisms, such as simple sequence repeats, have been widely used as DNA markers to identify QTLs and genes and to facilitate rice breeding. Recently, next-generation sequencing has produced deep sequences that allow genome-wide detection of indels. These polymorphisms can potentially be used to develop high-accuracy polymerase chain reaction (PCR)-based markers. ...
abstract this research was conducted in hamadan province for evaluation of potato cultivars reaction to cultivation date. this experiment was performed in split plot design based on randomized complete block in thee replication with two factors, containing, i. main plots are planting date including: 9 april, 25 april, 10may, 26may, 10 june, 26 june 2. and subplots are cultivar with three levels...
BACKGROUND Korean ginseng (Panax ginseng) is one of the most important medicinal plants in the Orient. Among nine cultivars of P. ginseng, Chunpoong commands a much greater market value and has been planted widely in Korea. Chunpoong has superior quality "Chunsam" (1st grade ginseng) when made into red ginseng. METHODS A rapid and reliable method for discriminating the Chunpoong cultivar was ...
