the present experiments is deciding to study the effect of hematite and volcanic ash on growth and physiological traits in sorghum factorial in a randomized complete design with  treatments and replications treatments consisted of volcanic ash concentrations (0, 0.25 and 0.5 g), hematite at three concentrations (0, 0.25 and 0.5 g), respectively. the results showed that the largest radicle and p...

salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...

In order to evaluate effect of salinity on germination and early seedling growth of lentils a laboratory experiment was conducted at Biotech Research Center of the University of Zabol, in 2011. The experimental design was a completely randomized with five NaCl solution, together with seven replicates. The seeds were germinated in Petri dishes, on with 10 mL of either double-distilled water (con...

in order to investigate the effects of seed inoculation with plant growth promoting rhizobacteria (pgpr) on germination components and seedling growth of corn (zea mays l.), a factorial experiment based on randomized complete block design with three replications was conducted at the seed technology laboratory of mohaghegh ardabili university, iran, during 2008. studied factors were: corn cultiv...

To determine the effect of salt stress on seed germination of Leymus species, seeds of Leymus racemosus (Lam.) Tzvel., Leymus angustus (Trin.) Pilger, Leymus multicaulis (Kar. et Kir.) Tzvel., Leymus duthiei (Stapf) Y. H. Zhou et H. Q. Zhang and Leymus secalinus (Georgi) Tzvel. were treated with NaCl solutions of different concentration: 0 mmol/L, 100 mmol/L, 200 mmol/L, 300 mmol/L, 400 mmol/L ...

to study the effects of sowing dates on seed germination and on seed vigor of 12 spring rapeseed cultivars, an experiment was performed in years 2005-2006. during the first year, 12 cultivars of spring rapeseed were planted in the research field of seed and plant improvement institute, karaj, iran. during the second year, standard germination test was conducted to study the performance of the s...

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...

due to extent of zinc (zn) deficiency in soils of iran and its deficiency in human diet, this study investigated the effect of zn sulfate foliar applications (non-foliar application, 0.5 g/l at stem elongation stage, 0.5 g/l at stem elongation and grain filling stages, 0.5 g/l at stem elongation and 2 g/l at grain filling stages) on yield and its components (farm sector) and influence of grain ...
