this study was conducted to quantify germination response of annual savory (satureja hortensis l.) to temperature and water potential. for this purpose, seeds were exposed to different temperature (12, 15, 20, 25, 30, 35, 37 and 40°c) and water potential (zero, -0.1, -0.3, -0.5 and -0.7 mpa) treatments in seed research lab., gorgan university of agricultural sciences and natural resources in 20...

This research was conducted to assessment effect of different concentrations of sodium hypochlorite along several times on quantitative parameters of wheat seeds affected by Aspergillus flavus fungus via factorial experiment according randomized complete block design with four replications. The treatments consisted four concentrations of sodium hypochlorite or NaClO (C1= 2%, C2= 4%, C3= 6%, and...

in order to study effect of seed weight on germination and growth of wheat seedling, an experiment in seed technology laboratory of aboureihan paradise university of tehran in 2005 has been done. in this experiment, at first stage, the seeds separated by longitude step, latitude step and set frequency parameters of gravity separator set. in second stage, 10 treatments of 1000 seed weight entere...

the effects of environmental factors on germination and emergence of hoary cress seeds were examined in laboratory and field experiments. germinability of hoary cress under light/dark conditions (90%) was significantly higher than when seeds were incubated under continuous dark (78%). hoary cress could germinate in a broad range of temperatures (15/6, 20/10, 25/15, 30/15, and 35/20?c). the germ...

present study was conducted to investigate the effects of different osmotic potentials (0.0 mpa, -0.4 mpa, -0.8 mpa and -1.2mpa) induced by nacl and polyethylene glycol-6000(peg) as salinity and drought stress respectively on germination and early growth of two inbred lines of maize (mo17 and b73). the objective was to compare the germination ability between tow maize inbred lines in salt and d...

abstract this experiment, conducted to examine the effects of temperature and photoperiod on seed germination of watergrass (echinochlo aoryzoides) as a new-introduced and barnyardgrass (e. crus-galli) as a common weed species in rice fields of guilan province. this study was consisted of two separate experiments. at the first study, germination responses of two species to different temperature...
