A local leaf burning causes variation potential (VP) propagation, a decrease in photosynthesis activity, and changes in the content of phytohormones in unstimulated leaves in pea plants. The VP-induced photosynthesis response develops in two phases: fast inactivation and long-term inactivation. Along with a decrease in photosynthetic activity, there is a transpiration suppression in unstimulated pea leaves, which corresponds to the long-term phase of photosynthesis response. Phytohormone level analysis showed an increase in the concentration of jasmonic acid (JA) preceding a transpiration suppression and a long-term phase of the photosynthesis response. Analysis of the spatial and temporal dynamics of electrical signals, phytohormone levels, photosynthesis, and transpiration activity showed the most pronounced changes in the more distant leaf from the area of local stimulation. The established features are related to the architecture of the vascular bundles in the pea stem.

豌豆植物局部刺激诱导的电和光合作用活动及植物激素含量的时空动态

局部叶片燃烧会导致豌豆植物中未刺激的叶片中的变异电位（VP）传播，光合作用活性降低以及植物激素含量的变化。VP诱导的光合作用分为两个阶段：快速失活和长期失活。随着光合作用活性的降低，豌豆叶片中的蒸腾作用受到抑制，这与光合作用响应的长期阶段相对应。植物激素水平分析显示，在蒸腾抑制和光合作用长期响应之前，茉莉酸（JA）浓度增加。分析电信号的时空动态，植物激素水平，光合作用，蒸腾作用表明，离局部刺激区域较远的叶片变化最为明显。建立的特征与豌豆茎中维管束的结构有关。
