Pulsed power technology shows novel effects in the fields of biotechnology. Pulsed electric field (PEF) has been studied on biological cells for a decade. Many investigations have done using mammalian cells, whereas there are less studies carried out using plants. In this study, various pulsed electric fields (PEFs) were applied to roots of the lettuce, the results show that it is able to control the growth rate by controlling input energy to the lettuce. Also, chlorophyll fluorescence measurement was employed to reveal PEF effects to the leaf lettuce, when PEF was applied to the lettuce leaf. Hence, the technique of chlorophyll fluorescence has become ubiquitous to reveal photosynthesis mechanism or stress reactions of photosynthetic organisms in ecophysiology studies in recent years. In the experiments, some parameters were measured by chlorophyll fluorescence from the leaf lettuce.
