in order to investigate the effect of water stress at heading stage on grain yield and yield components of eight wheat cultivars, in 2008 year a research was conducted in the two regions esfahan and ardestan by using split plot in a randomized complete block design with three replications which that two irrigation treatments included custom and late season water stress were main factor and 8 wh...

one of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. in order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...

for evaluation of drought tolerance of sugar beet genotypes by assessment of the drought tolerance indices under mild and severe stresses, furrow irrigated field experiments were carried out at zarghan research station in 2002 and 2004, and at motahari research station (located inkaraj) in 2002, 2003, and 2004. the experimental design was split plot, with a randomized complete block arrangement...

the aim of this study was to investigate the effect  of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named bp mashhad, bp karaj and 191. the experiment was in a split  plot  based on randomized complete block  design , carried out  at motahari research station of sugar beet seed research institute ...

to study general combining ability (gca) and estimation of heterosis in sunflower inbred lines for seed yield and other three agronomic traits, 68 inbred lines crossed with open pollination variety lakumka. in next year inbred lines along with topcrosses were planted in rcbd with 2 replications under two moisture conditions in sararood agricultural research station. analysis of variance in both...

background : occupational stress is a psychosocial dimension of occupational health concept on social determinants of health, especially, job & environmental condition. recently, staff network of different government universities of thailand have called higher education commission, and ministry of education, thailand to resolve the issue of gov-ernment education policy (e.g. wage inequity, poor...

to evaluate the effects of water deficit stress in barley germplasm collection of national gene bank ofiran, 25 genotypes collected from arid and semi arid provinces of iran and 3 sample cultivars werestudied in two environments including: non-stressed and water deficit stress. agronomical, phenologicaland morphological traits were measured. stress indices were calculated to determine tolerant ...

future climate changes are expected to increase risks of drought, which already represent the most common stress factor for stable barley (hordeum vulgare l.) production in iran. up to now, extensive research projects have been done to study effects of drought stress on the antioxidant enzyme activity. while there is a few works of such studies on the field condition. in order to study of water...
