Gundelia tournefortii L. is adapted to mountains area climate, and the germination of this plant is not easily. This researchconducted to study the effect of different seed treatments in various treatment durations in two experiments in petri dish in thelaboratory and in seedling tray in the lath house to breaking seed dormancy and germination stimulus. Results indicated thatthere is significant enhancement of germination by all treatments and the maximum germination percentage was obtained byseed freezing 99.17% in the laboratory and 93.33% in the lath house for all treatment durations 12, 14, 48 and 72 hours. Theother parameters of seed germination like germination speed, peak value, mean daily germination, mean germination time,germination value, radicle length, radicle elongation velocity, plumule length, plumule elongation velocity, seedling freshand dry weight escalated by seed freezing and seed soaking in tap water at all soaking durations 12, 24, 48 and 72 hours.Gundelia tournefortii L. germinated seed was an anatomically examined by paraffin method and calculated diploid number ofchromosomes 2n=2x=18 by aceto-carmine squash methods
