Wheat is a crop with spring and winter types and wide adaptability to different climate conditions. The wide adaptability of wheat is mainly controlled by three groups of genetic factors and among them vernalization (VRN) genes play pivotal role in determining spring and winter types. In this study, 395 Iranian wheat landraces were characterized with specific primer pairs designed based on VRN-...

Nitrogen (N) losses negatively impact groundwater quality. Spring wheat genotypes varying in N-fertilizer recovery were studied (by using lysimeters) for their potential to minimize NO3-N leaching during spring and summer, over a three-year period. Additionally, we examined to what extent root growth and NO3-N leaching explain the well-known difference found between apparent and isotopic N reco...

in study was conducted in two separate experiments in 2011-2013 in seeds and plant improvement institute. in the first experiment, status growth scion and resistance to spring late frost and content proline in 10 genotypes and cultivar almond, grafted on gf677 rootstock included touno, non pariel, shokofeh, sahand, mamayi, shahrood 12, a200, 1-25, 1-16 and 13-40 with 10 replication as a complet...

The effect of short- and long-term cold treatment on the abscisic acid (ABA) and cytokinin (CK) metabolism, and their main biosynthesis- and signaling-related genes were investigated in freezing-sensitive and freezing-tolerant wheat genotypes. Varieties Cheyenne and Chinese Spring substituted with the 5A Cheyenne chromosome, which represented freezing-tolerant genotypes, were compared with the ...

Wheat is able to cold acclimate in response to low temperatures and thereby increase its frost tolerance and the extent of this acclimation is greater in winter genotypes compared to spring genotypes. Such up-regulation of frost tolerance is controlled by Cbf transcription factors. Molybdenum (Mo) application has been shown to enhance frost tolerance of wheat and this study aimed to investigate...

18 1 (mean 28 mg kg). Spring wheat cultivars pos19 sessed higher Fe-grain concentrations than winter 20 wheats. By contrast, winter wheats showed higher 21 Zn-grain concentrations than spring genotypes. 22 Within spring wheat, a strongly significant positive 23 correlation was found between Fe and Zn. Grain 24 protein content was also significantly (P < 0.001) 25 correlated with grain Zn and Fe...

potato (solanum tuberosum l.) cultivation in two different climates causes difference in its growth process.the most frequently used indicators of growth for plants are the tuber growth rate (tgr), crop growth rate (cgr) and leaf area index (lai). shoot dry weight is the easiest, quickest and least costly component to measure the competitive features of plants.the results of some studies showed...

in order to compare the agronomic characteristics of developed iranian spring wheat genotypes (selective cultivars from: endemic landraces of wheat, interal hybrid wheat and international centers) and also the identifying traits affecting grain production under different concentration of iron in the soil solution, a randomized complete block design with a split-plot arrangement with 30 wheat ge...

In this study, 321 winter and spring wheat genotypes were analysed for twelve nutritionally important minerals (B, Cu, Fe, Se, Mg, Zn, Ca, Mn, Mo, P, S and K). Some of the genotypes used were from multiple locations and years, resulting in a total number of 493 samples. Investigated genotypes were divided into six genotype groups i.e., selections, old landraces, primitive wheat, spelt, old cult...
