| 以草莓为供试材料,研究其生长性状及叶绿素光系统Ⅱ的荧光参数对声频处理的响应。试验结果表明:声频处理35 d后,草莓的开花数、结果数和叶绿素含量均有所提高,其光系统Ⅱ的初始荧光F0、反映电子传递能力的ΦPSⅡ略有升高,最大荧光Fm及反映光化学效率的Fv/Fm值、反映光下开放的PSⅡ反应中心原初光能捕获效率的F'v/F'm均显著上升。表明声频处理后,PSⅡ反应中心的潜在活性增强,原初光能转换效率提高,电子传递和光化学效率上升。 |

| Abstract: |
| In this thesis, changes of growing and fluorescence parameters of strawberry by application of sound frequency treatment were explored. The results showed that the number of the flowers, the fruits, as well as the content of chlorophyll were increased after 35 days of sound frequency treatment. The maximal fluorescence(Fm), photochemical efficiency of PSⅡ(Fv/Fm),non-photochemical quenching(NPQ) increased markedly under sound frequency treatment after 35 days, while change of the initial fluorescence (F0), photochemical quenching (qP) were not prominent. These results suggested that acoustic frequency treatment could improve the activity of PSⅡ reaction centers, enhance the electron transport and the photochemical efficiency of PSⅡ. |
