the effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...

this experiment was conducted in germinator in order to study the effects of water potential on seed germination, rate of germination and seedlings growth of four medicinal plants (coriandrum sativum, plantago psyllium, discorinia sophia and portulaca oleracea). four water potential inclouding distilled water as control (0), -0.37, -0.59 and –0.81 mpa which made by different salts (nacl, cacl2 ...

laboratory experiments were performed to determine the effect of various scarification treatments at four temperature regimes on germination of licorice seeds . a randomized complete block design with four replications was used. germination counts were made every day for 2 weeks. at 50c, none of the chemically and mechanically scarified and non scarified seeds germinated. at 15, 25, and 350...

germination response to temperature is different among plant seeds. germination rate and percentage is maximal at optimum temperature (s), and then reach to zero at base and ceiling temperatures. the objective of this research was (1) to evaluate germination response of snail medic seeds to temperature and (2) to determine cardinal temperatures of germination rate and percentage. therefore, see...

low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...

in order to evaluate the effects of methanol on germination percentage, germination speed index, plumule and radicle length, plumule and radicle dry weigh, vigor index and consumed endosperm of bean in condition of water deficit, a factorial experiment done based on completely randomized design with three replications. the first factor was different levels of methanol included 0 (control), 5, 1...

this research was carried out to investigate allelopathic effect of peganum harmala on seed germination of bromus tectorum. aboveground and underground tissues of peganum harmala in addition to its seeds were collected from bijar rangelands. collected materials of root, leaves, stem, seeds and a complex of mentioned parts were dried and powder. the research was performed at the greenhouse condi...
