tall fescue is a cool season grass widely distributed and adapted to different environmental conditions of iran. superior seed-yielding potential of the plant is an important criterion during the seed reproduction phases of breeding new cultivars and as well under commercial seed production conditions. in order to evaluate germplasm and investigate the pattern of genetic variation of seed trait...

abstract to assay the effect of acetylsalicylic acid pretreatment on enhancement of yield and yield components of barley (reihan-03) under water stress condition, an experiment was conducted as a spilt-plot arrangement based on randomized complete block design with four replications at the research field of shahid bahonar university of kerman, iran, in 2012-2013. irrigation condition was arrang...

High grain protein content (GPC) is a frequent target of wheat breeding programmes because of its positive effect on bread and pasta quality. A wild wheat allele at the Gpc-B1 locus with a significant impact on this trait was identified previously. The precise mapping of several senescence-related traits in a set of tetraploid recombinant substitution lines (RSLs) segregating for Gpc-B1 is repo...

To evaluate the effects of O3 on the net photosynthetic rate in flag leaves of rice (Oryza sativa L.) based on stomatal O3 flux and reactive oxygen species (ROS) scavenging enzyme activities, the Japanese rice cultivar Koshihikari was exposed to O3 for 1 month after heading in O3-exposure chambers. During the exposure period, rice plants were exposed to charcoal-filtered air or O3 at 60 or 100 ...

in order to providing selection indices using heritability and correlation effective traits on yield and multiple regression an experiment was conducted by 265 f3 families as well as parents and f1 related to gharib × khazar population in 2009 at gonbad high education center fields. days to repining (0.97) and panicle number and flag leaf length (0.66) had maximum and minimum heritability, resp...

to evaluate the response of wheat to drought stress and salicylic acid, this field experiment was carried out at the experimental farm of college of agriculture, university of shahid bahonar kerman, iran in 2011-2012, in a split-plot arrangement using completely randomized block design with four replications. main plot was irrigation (normal irrigation and cut off at flowering) and sub plot was...

Senescence is a highly regulated process which is under genetic control. In monocarpic plants, the onset of fruit development is the most important factor initiating the senescence process. During senescence, a large fraction of plant nutrients is reallocated away from vegetative tissues into generative tissues. Senescence may therefore be regarded as a highly effective salvage mechanism to sav...

Stagonospora nodorum blotch (SNB) caused by Stagonospora nodorum is a severe disease of wheat (Triticum aestivum) in many areas of the world. S. nodorum affects both seedling and adult plants causing necrosis of leaf and glume tissue, inhibiting photosynthetic capabilities, and reducing grain yield. The aims of this study were to evaluate disease response of 280 doubled haploid (DH) individuals...
