| 摘 要： | 研究了声频处理对番茄品种"合作918"植株生长性状以及光合、荧光参数的影响。结果表明:声频处理不仅可以显著提高番茄的开花数、结果数、茎粗以及叶片叶绿素含量,而且对光合、荧光参数也有一定的积极影响,其中胞间CO2浓度、蒸腾速率、光系统Ⅱ效率、电子传递速率、水分利用率以及羧化效率等显著升高,气孔限制值显著下降。说明声频控制技术对番茄的生长及光合作用具有一定的促进作用。

| Abstract: | The effects of acoustic frequency treatment on the growth character, photosynthetic and chlorophyll fluorescence pa- rameters of tomato variety ＂Hezuo 918＂ were studied. The results indicated that acoustic frequency treatment could not only enhance the flowering number, fruit number, stem diameter and leaf chlorophyll content of tomato, but also improve the photosynthetic and fluorescence parameters, specially it could obviously increase the content of inter - cell CO2 concentration, transpiration rate, efficiency of photosystem 11, velocity of electron transport, water utility efficiency and carboxylation efficiency, and significantly reduce the stomata limited value. It was concluded that the acoustic frequency treatment played an important role in promoting the growth and photosynthesis of tomato. |
