Finding the appropriate parents for breeding programs is the main aim of selecting in drought tolerant crops and landraces under stresses conditions. In present survey, eigthey wheat landraces and varieties from different areas of Iran were evaluated in Gorgan agricultural research station (as a normal or potential yield) and Mazrae-Nemoneh (as under stress condition) during two years (1999-200...

Canola (Brassica napus L.) as one of the oilseed crops has recently received lots of attention due to its suitable oil quality and high oil percentage. To evaluate the effect of water deficit stress on canola genotypes with regard to yield, drought tolerance quantitative indices and identify drought tolerant genotypes, an experiment was conducted in research farm of seed and plant improvement I...

Half-sib mating is an appropriate approach to estimate additive variance component of quantitative traits. This research was conducted to estimate genetic parameters of physiological traits and their response to drought stress in Dactylis glomerata. Twenty five half sib families derived from poly cross of 25 parental genotypes were evaluated under two moisture environments (normal and drought c...

Water shortage is one of the most important limiting  factors for  crop production, that affected growth and yield by changing physiological conditions. This study was carried out to investigate effect of oxidative stress on antioxidant defense mechanism in Research greenhouses of Birjand University in 2014. A factorial arrangement of treatments based on randomized complete block design (Due to...

this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...

Evaluation of varieties and soybean lines under drought stress helps to breeders for detecting of stable and high-yielding genotypes. In this regard an experiment was conducted in randomized complete block design with three replications under normal and drought stress conditions across two locations (four environments). The results of combined analysis of grain yield/plant revealed effects of s...

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...
