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 Ⅱ.
