ABSTRACT: Lathyrus aphaca is an aggressive dicotyledonous weed. The effect of different agroecological components/factors on the germination ecology of this weed was explored under a glasshouse and laboratory condition in 2014. The germination response of L. aphaca was lower at high temperature while maximum seed germination was found at 15/12 oC (day/night). Light significantly stimulated L. aphaca germination; nevertheless, substantial germination occurred under dark conditions. More than 86-90% of L. aphaca seeds germinated at pH level of 6.2-7.5. A significant quantity of seed germinated at 250 mM NaCl. There was no germination at -1 MPa. When the temperature was lower than 20/15 oC (day/night) initiation time of germination and germination index (GI)...
