A field experiment was carried out during the 2013-2014 growing season in Lorestan Province (Iran) to evaluate the effect of three planting densities (30, 55, and 83 plant.m-2) on growth indices and grain yield of four chickpea cultivars (Azad, Hashem, Arman and ILC482) under the fall dry land farming condition. The experiment design was factorial based on a randomized complete block design (RC...
Antioxidant activities in the leaves and fruits of wild Vaccinium arctostaphylos (locally named Qare-Qat) from diff erent regions of Iran were evaluated using the stable 1, 1-diphenyl-2-picrylhydrazyl free radical and ferric reducing/antioxidant power methods. Variations in antioxidant activity, total phenolic, anthocyanin, and fl avonoid content in fruit samples among genotypes was much greate...
in agricultural meteorology, the growing season is the period within each year when crops can be grown from a view of thermal conditions. this period is in general, between the last and first frost dates in spring and autumn when temperature is above a specific threshold. there are two other definitions when using a 5 °c as threshold. one of the methods employed in studying future climate is us...

Using daily minimum air-temperature (Tmin) data from the state of Illinois, the dates of spring and fall freezes – and the resulting growing-season length – are examined for trends during the period 1906–1997. Of the stations in the Daily Historical Climate Network, most show trends toward earlier spring freezes; however, trends in fall freezes are not consistent over the station network. Altho...
the objective of this study was to obtain relationships between plant leaf area (cm2plant-1) with leaf dry weight (g plant-1), vegetative dry weight (g plant-1) and plant height (cm) in faba bean (vicia faba l.). the experiment was conducted at the research farm of gorgan university of agricultural sciences in 2011-2012 growing season. the experimental design was a randomized complete block des...
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
Onion thrips, Thrips tabaci Lindeman, is a worldwide pest of onion whose feeding damage and transmission of Iris yellow spot virus (IYSV) may reduce onion yields. Little is known about the seasonal dynamics of T. tabaci dispersal, the distance of dispersal, or the movement of thrips infected with IYSV during the onion-growing season. To address these questions, T. tabaci adults were collected u...
tomato is one of the most important vegetables in iran and throughout the world with crop loss caused by several viruses. this survey was carried out to detect the viruses causing mosaic symptoms on tomato in yazd city (iran). a total of 451 samples of tomato leaves showing mosaic symptoms were collected from fields and greenhouses during 2012-2013 growing season. collected samples were analyze...
