Understanding the reaction form and biochemical response of wheat cultivars about the salinity stress can help to better understand the defense mechanisms and identify the indicators and biomarkers of tolerance screening for salinity stress in this strategic plant and other field crop. For this purpose, biochemical traits related to salinity tolerance of wheat cultivars were evaluated as a f...
A factorial experiment with forty one triticale genotypes and two wheat cultivars (‘Kavir’ bread wheat cultivar and ‘Dipper-6’ durum wheat cultivar as salt-tolerant genotypes) as the first factor and six salinity levels of 0, 0.5, 1, 1.5, 2 and 2.5 percent (0, 85, 170, 255, 340 and 425 mM) of NaCl as the second factor was conducted. Results indicated that the increase of salinity level has lead...
to evaluate the role of effective factors on competition of two wheat cultivars against two species of narrow leaf and broad leaf weeds this study was conducted as two separated experiments based on a randomized complete block design with 3 replications at agricultural faculty of bu-ali sina university, in 2008-2009. in both experiments, alvand and sayson cultivars were planted with densities o...
Fusarium head blight (FHB) is a serious disease of wheat and barley that is best controlled by host resistance. In KSU Extension publications, the reaction to FHB for winter wheat cultivars is reported to producers using a 1-9 scale where 1-3 = resistant, 4-6 = intermediate, and 7-9 = susceptible. This research sought to determine how many location-years are needed to accurately determine the r...
The effect of drought stress and abscisic acid (ABA) applied at tillering stage (55 days after sowing) was compared in 2 wheat cultivars differing in drought tolerance. The activities of superoxide dismutase (SOD) and peroxidase (POD) and contents of endogenous ABA in plants were measured at 3 days of drought stress in cv. Chakwal-97 (drought tolerant) and cv. Punjab-96 (drought susceptible). A...
Fusarium head blight (FHB), primarily caused by Gibberella zeae (anamorph1⁄4Fusarium graminearum), is a devastating disease that causes extensive yield and quality losses to wheat and barley throughout the world. Antagonists that suppressed FHB in earlier greenhouse studies were tested in a series of field experiments at different geographical locations in the United States in 1998–2000. In mos...
the experimental was split plot in a randomized complete block design with three replications. in this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 n) kg.ha-1 urea and wheat varieties, including cultivars, sepahan and sw were placed in the subplots. results showed that nitrogen fertilizer and cultivar were significant effects on maximum lig...
tak-ab is a new winter bread wheat cultivar developed from evaluation of icarda-turkey-cimmyt international bread wheat germplasm to supplementary irrigation areas. study of new cultivars under supplementary irrigation in maragheh and ardebil research stations (2005-2012) showed that, tak-ab had high grain potential under supplementary irrigation conditions. based on results means of grain yiel...
the eggs and larvae of the indian meal moth, plodia interpunctella (hübner), are widely used in mass rearing of parasitoids and predators. feeding indices and some biological parameters of p. interpunctella were studied on bran of different wheat cultivars ('back-cross roshan', 'khooshe pishgam', 'khoshki line 9', 'arg', 'alvand', 'pishtaz', 'ws-89-2', 'sepahan' and 'bam') when incorporated int...
