Plant Acoustic Frequency Technology (PAFT) aims to impose the plant with sound wave in special frequency which accords with plant meridian system so that it can increase plant production and decrease the use of fertilizer. The objective of this study was to identify indicators which relate to the effects of PAFT through analysis of photosynthetic processes and chlorophyll fluorescence traits in strawberry (Fragaria ananassa) leaf. The results showed that all these indicators were affected by sound wave frequency treatment. The number of flowers and fruits as well as the content of chlorophyll augmented. The net photosynthetic rate (PN) also remarkably increased. The maximal fluorescence (Fm), maximum photochemical efficiency of photosystem II (Fv/Fm), and non-photochemical quenching (NPQ) increased markedly under PAFT of 35 days while the change of the initial fluorescence (F0) and photochemical quenching (qP) showed actual but unobvious increases. These results further revealed that the acoustic frequency treatment could improve the activity of photosystem reaction center, and enhance the electron transport and the photochemical efficiency of photosystem I
