In this study, effects of extracts Lavander (Lavandula angustofolia M i l l e r.) seed and leaf on Zea mays L. and Lens culinaris M. seed germination percentage and postgermination seedling growth were investigated. Seeds were germinated in Petri dishes at 25 degrees C. Seed germination, seedling elongation was determined at day 14. In this study, the n-hexane extracts of the seeds and leaves of industrially grown lavender (Lavandula angustofolia M.) plant was used. After completing the mandatory pre-conditioning phases, the applications were initiated in order to determine their effects on the germination physiology on corn (Zea mays L) and lentil (Lens culinaris M.) by diluting the plant extracts by 5, 10 and 15% folds. Regarding the lentil seed, while the 15% lavender seed extract showed germination rates, it was observed that the plant extracts had significant effects on the germination of the seeds. As the result, the fact that the extracts of those plants show different allelopathic effects on the germination of the corn and lentil seeds indicates that such extracts may be utilised towards different goals in terms of agricultural, ecologic and physiologic aims.
