Estimation of genetic variation is very important in breeding programs and existing of high genetic variation lead to increase the response to selection. The objective of this study was to investigate genetic variation for agronomic traits and yield components in 12 alfalfa half-sib families. Thirty five individuals of each half-sib family were grown and analyzed basis of completely randomized ...

To investigate the effect of applying different amounts of municipal solid waste compost (MSWC) and sewage sludge (SS) on yield and concentration of some heavy metals including nickel (Ni), chromium (Cr), cadmium (Cd) and lead (Pb) in organs of green pepper plant, a pot experiment was conducted as a completely randomized design with seven treatments and four replications. Treatments included co...

A soilless cultivation experiment, in a medium containing sand, perlite and peat, based on Hoagland nutrient solution, was designed and carried out to investigate the growth and postharvest response of Zinnia to different concentrations of nitrogen (N) and calcium (Ca). Treatments included control 1 (without nutrient solution), control 2 (nutrient solution without N and Ca), and the mixtures of...

     Mutations induced by gamma irradiation are part of improving some important agronomic traits in crops.  Identifying the optimal mutagenic dose is considered to be the most crucial step in trials and generating mutated genetic materials. The goal of this study was to evaluate the effect of different doses of gamma ray (0, 150, 200, 250 and 300 Gy) on some plant early stages traits and bioch...

Sentence determine the stability mechanisms to stress in Agropyron trichophorum at test with four different levels of osmotic potentials resulted from PEG 6000 including 0, -3, -6 and -9 executed in factorial and accidental manner with four interactions in hydroponic environment. Three genotypes of Agropyron trichophorum pasture types were used Arak (3755), Semirom (3.13), and Faridan (4007) an...
