Isabgol (Plantago ovata Forsk) seed germination and emergence in response todrought (Polyethylene glycol 8000) and salinity stress (NaCl), temperature, pH andplanting depth were studied in laboratory and greenhouse experiments. Base,optimum and ceiling germination temperature were estimated as 3.35, 21.24 and35.04 oC, respectively. Isabgol seed is rather tolerant to low water potential and high...

in order to investigate factors affecting on seed germinating of london rocket (sisymbrium irio), lab experiments were set up in 2011 at the payamenoor university, mashhad, khorasan razavi province. effect of different concentrations of gibberellic acid (ga3) and cytokinin, wet and dry prechilling duration, hydrogen peroxide duration, ethanol, salt and osmotic stress and burial depth on seed ge...

response of seed germination of a crop to different environmental conditions is one of the most important determination factors to indicate its ability in competition with weeds. in order to evaluate the effects of water depth and temperature on the germination of different varieties of rice and barnyard grass, an experiment was conducted in the seed laboratory, faculty of agriculture, ferdowsi...

the response of tomato genotype cal-ji  against five salinity levels (distilled water as control, 25, 50, 75 and 100 mm) were studied at germination and early seedling stages. an experiment with conducted by using a completely randomized design (crd) with three replications. shoot and root length, shoot and root fresh weight, seed vigor, mean germination time, germination percentage and rate me...

in order to assess the genetic variability for seed germination parameters under salt stress in sunflower and corresponding qtl locations, an experiment was conducted using a population of 80 recombinant inbred lines obtained from a cross between pac2 and rha266. the experiment was arranged under a randomized complete block design with three replications in control and saline conditions. severa...

abstract- this experiment was carried out during the growing seasons of 2010 and 2011 at the agricultural research farm of bu-ali sina university, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. experiments consisted of two sets of treatment...

Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...
