Sesame is one of the oldest and most important oilseeds in Iran and the world due to its nutritional value. In the present study, 25 sesame landraces collected from different regions of the country were evaluated in terms of phenological, morphological and physiological traits in Urmia climate. The ANOVA results showed that there was a statistically significant difference between the landra...
We conducted a glasshouse experiment as a factorial in randomized study with six replications on pasture species of Schoenoplectus triqueter in Gonbad Kavoos University from 2012-2013. Treatments included height waterlogging in four levels (control, equal to the water surface, 10 cm below the water surface, 20 cm below the water surface) and waterlogging period over three levels (10, 20 and 30...
Drought stress is a critical and inevitable phenomenon damages successful crop production in various intensity every year in different parts of the world during different times. This research was done to evaluate the effects of drought stress on some traits related to leaf (leaf weight, leaf area and chlorophyll content) root (root weight) and shoot (weight and length) further enzymatic antioxi...
Predictions of forest succession, diversity and function require an understanding of how species differ in their growth, allocation patterns and susceptibility to mortality. These processes in turn are affected by allometric constraints and the physiological state of the tree, both of which are coupled to the tree's labile carbon status. Ultimately, insight into the hidden labile pools and the ...
هدف از این تحقیق یافتن ارتباط بین نحوه نگرش زبان آموزان به موفقیت و شکستشان و نوع شخصیت آنها است. 216 زبان آموز، 111 پسر و 105 دختر، در سطح متوسط که در آموزشگاه زبان انگلیسی شکوه مشغول به تحصیل بودند در این پژوهش شرکت کرده اند. شرکت کننده ها دو پرسشنامه neo-ffi و atfll را تکمیل کرده اند. نتیجه نشان داد که: احساسات با توافق پذیری و وظیفه شناسی ارتباط مثبت و با روان نژندی ارتباط منفی دارد. تصور ا...
in order to have a successful breeding program, it is important to determine the relationship among the traits. this study was conducted at research farm of isfahan university of technology to evaluate relationships among some of the agronomic and physiological traits and grain yield of ten bread wheat cultivars in optimum and stress moisture (irrigation after 70±3 and 130±3 mm evaporation from...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
Safflower oil with high oleic acid content has a great value for both food and non-food uses. The trait is mainly controlled by recessive alleles at the Ol locus, although the influence of modifying genes has been suggested. The objective of the present research was to study the inheritance of very high oleic acid content (>85%) and its relationship with other traits such as nuclear male steril...
Now days, turf management has encountered with water deficit, mostly due to low precipitation also industrial, agricultural and household demand and consumption. So, the objective of this project was to identify drought tolerance of warm and cool season turfgrass cultivars to different levels of regulated-deficit irrigation. The field experiment was set out in a split-plot based on completely r...
Theory predicts that physiological costs of producing elaborate phenotypes assure the honesty of sexually selected traits. It is generally assumed that these physiological processes drive sexually selected displays. However, a recent study by Safran and colleagues demonstrates that the manipulation of plumage ornaments in barn swallows alters the temporal course of circulating androgens, thus r...
