Abstract: To test the sound’s effect on plant and its contribution in drought tolerance, plants were subjected to various sound frequencies for an hour. After 24 h sound treatment, plants were exposed to drought for next five days. During the experiment it was observed that sound initiated physiological changes showing tolerance in plant. Sound frequency with ≥ 0.8 kHz enhanced relative water content, stomatal conductance and quantum yield of PSII (Fv/Fm ratio) in drought stress environment. Hydrogen peroxide (H2O2) production in sound treated plant was declined compared to control. ThermaCAM (Infra-red camera) a software which was used to analyze the plant images temperature showed that sound treated plant and leaf had less temperature (heat) compared to control. The physiological mechanism of sound frequencies induce tolerance in rice plants are discussed.
Key words: Frequency, Sound, Drought, Infra Red, Images.
