this research was investigated to study relationship among seed yield, seed yield components and morphological traits and their direct and indirect effects on seed yield of 100 safflower genotypes in two water environments (normal and drought stress) at research farm of isfahan university of technology during 2012. seed yield had positive correlation with number of head per plant, seed per head...
The purpose of present study was identifying superior cotton varieties (Gossypiumhirsutum L.) under drought stress and normal conditions using GGEBiplot and GTBiplot. The experiment was conducted in a randomized complete block design with three replications and 14 treatments under normal and stress conditions in the research station of Birjand University in 2013-2014. Cotton genotypes were: Arm...
climate changes due to global warming is affecting world agriculture adversely. heat stress due to global warming has turned to one of the most important factors reducing quantity and quality of plants production such as tomato. despite of wide cultivation of tomato and high temperature effects on its production, unfortunately; research in this area is scarce. this study was conducted to invest...
Drought stress is one of the major abiotic stresses that limits rice productivity in the world. In this study 83 diverse rice genotypes were evaluated under reproductive-stage drought stress and non-stress conditions in a completely randomized design with three replications. Eleven well known stress tolerance and susceptibility indices were calculated based on the grain yield under stress and n...
In order to evaluate intra-genomic variation and regression analysis of grain yield and its components using two wheat substitution lines series including substitution lines of ‘Timstein’ and ‘Red Egyptian’ into genetic background of ‘Chinese Spring’ and their parents in a randomized complete block design with four replications under water-stress and non-stress conditions in a greenhouse at 201...
In the sub-tropics, water and nitrogen are the most important factors limiting the grain yield of maize. The effect of nitrogen (N) rates and drought stress at different growth stages of maize were investigated. Nitrogen treatments consisted of 100, 150, and 200 kgN.ha-1 from the urea source while water stress treatments were composed of irrigation-off since the early 10-leaf stage to emergenc...
to evaluate canola cultivars response to physiological characteristics and grain yield end seasonal drought stress in weather condition of ahvaz, farm experiments were done at research farm of khuzestan agriculture and natural resources center. during 2007-2008 and 2008-2009 crop years. farm test comprised drought stress was done as split plot form with randomize complete block design with four...
mprovement of N2 fixation might be an effective strategy in peanut breeding for high yield under drought stress conditions. However, under water limited conditions peanut varieties having high water-use efficiency (WUE) are favorable. A pot experiment was conducted under greenhouse conditions at Khon Kaen University, Thailand during December 2002 to May 2003, and repeated during June 2003 t...
This research was conducted to study relationships among yield and yield components in Orchard grass (Dactylis glomerata). For this purpose 25 half sib families derived from poly cross of 25 parental genotypes were evaluated under two moisture environments (normal and drought conditions) according to a randomized complete block design at the research farm of Isfahan University of Technology. Th...
Increasing the yield of wheat (Triticum aestivum) requires choosing resistant and compatible cultivars to different climatic conditions. In order to study the effects of salinity and drought stress on grain yield, Study of stress tolerance indices and identification of tolerant genotypes to salt and drought stress, 20 different Wheat (Triticum aestivum) genotypes were assessed in a Randomized ...
