Abiyotik stres faktörleri arasında yer alan farklıses dalgalarının oluştuğu ses alanlarının meydana getirdiği ses stresleri,alternatif mekanik bir stres olarak bitkilerin büyüme ve gelişmelerine etkietmektedir. Çalışmada tıbbi amaçlı olarak değerlendirilen ikifarklı tıbbi ve aromatik bitkiler (Lavandulaangustifolia, Rosmarinus officinalis) sabit tutulan 1000 Hz frekansdeğerinde 3 farklı ses şiddeti düzeyinde (95dB, 100dB,105dB) ses dalgalarınamaruz bırakılmışlardır. Farklı şiddetteki ses stresine tabi tutulan bitkilerde;bitki boyu (cm), yaprak sayısı (adet/bitki), gövde çapı (mm), bitki taze vekuru herba ağırlıkları (g/bitki) ile kök taze ve kuru ağırlıkları (g/bitki)ölçülmüş ve bitki kuru herbada uçucu yağ oranları (%) belirlenmiştir. Sonuç olarak;Lavandulaangustifolia, Rosmarinusofficinalis ses stresi bitki büyüme parametrelerini ve uçucu yağ oranlarınıetkilemiştir.

Sound stresses included in abiotic stress factorscreated by the sound areas in which sound waves form affect growth anddevelopment of plants as an alternative mechanic stress. In this study, twomedicinal and aromatic plants (Lavandulaangustifolia, Rosmarinus officinalis)which have an important place in human health, were exposed to sound waves at 3different dB values (sound intensities are 95 dB,100dB,105dB). During theperiod of application the frequency values 1000 Hz adjusted as constantly.Sound stresses that created by the sound fields in which sound waves that havedifferent dB values affect growth and development of plants as an alternativemechanic stress. In this research, plant height (cm), number of leaves/plant,diameter of stem (mm), fresh and dry weight of root, fresh and dry weight ofshoot (leaves + stem) were measured and essential oil rate (%) were determined.The results indicated that growth parameters and essential oil of, Lavandula angustifolia, Rosmarinus officinalis were affected bysound intensities.
