due to the use of secale montanum for different rangelands reclamation across the country, management of these ecosystems need to be aware of its ability to environmental stresses. this research investigated the effect of pollutant element of cu and pb on seed germination and growth of this species in laboratory. therefore, the effect of five treatments (control, 50, 100, 150, 200ppm) of pb (no...

Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...

tall fescue (lolium arundinaceum (schreb) sj darbysh.) is one of the fescue species that widely used as forage grass. tall fescue is self-incompatible and wind cross pollination. this study was conducted to study agronomic and morphological characteristics of 25 polycross families of tall fescue during 2011 and 2012 at research station farm in isfahan. number of days to pollination, height of p...

this study was carried out to evaluate the association between laboratory seed characteristics and seedling emergence of canola cultivars that it's were produced under different irrigation regime and planting date. the treatments were included two planting date and two levels of irrigation (main factors) and seeds of five canola cultivars (sub factor) which in first year (2006-2007) had be...

Too often crop production is facing with different intensity of cold damage. In some years the damage is severe and has a large social and economic consequence. Therefore, selection and introduction of cold tolerant cultivars is very effective in reducing cold damage and increasing crop production. Frequently, in winter safflower yield trails in Isfahan province, depending on the intensity of w...

Twelve cultivars of bambara groundnut were sown for evaluation of variability and genetic correlation among agronomic characters and seed yield in 2004 and 2005 in a randomized complete block design with three replications. Combined analysis of variance revealed highly significant effects (p<0.05) for genotypes (G), year (Y) and G x Y interaction for most characters evaluated. Estimates of geno...

in order to evaluate the effects of seed priming and different levels of nitrogen on yield and yield components of two corn (zea mays) hybrids, an experiment was carried out as split plot factorial based on a randomized complete block design (rcbd) with four replications in agricultural research station of shahrood university of technology. the treatments were urea levels (150, 250, 350 kg/ha) ...
