This reaserch study germination for three species from Zyophyllaceae family : Fagonia bruguieri (shuika) , Peganum harmala (harmal) , Tribulus terresteris ( kutob) .

The experiment condected by repeated three times and emergenc of radicale indication of germination .

So two sets of seeds have used in study , one set after ripining season directly and other six month later .

First stage planted in natural inviroment by soil bringing from plant,s inviroment in pots in room temperature in three times periods in January , February and April .The result: germination has failed with new ripining seeds but Peganum harmala has small percentge of germination , when the other set of seeds have succeeded germination at same three periods with different percentage among three species .

The other experiment conducted in laboratory under physical conditions to breaking dormancy of seeds .

The result: three species have different ranges for germination under different inviromental conditions .
